denticulatis subtus ad venas venulasque ochraceo-hirtellis utrinque setulis basi papillatis asperis, petiolo muricato; calycis glabri lobis ovalibus obtusissimis foliaceis tubum elongato-obconicum æquantibus; corolla 24-pollicari curvata.-Oahu. (Leaves of one or two seemingly allied species were collected, without flowers or fruit.)

3. CYANEA? PILOSA (sp. nov.): caule frutescente; foliis subpedalibus membranaceis obovatis utrinque acutis vel acuminatis eroso-crenatis pilis brevibus mollibus hirsutis; racemis brevibus in pedunculo 1-2pollicari hirsutissimo paucifloris; floribus "parvis griseo-cæruleis" pedicellisque glabris; lobis calycis linearibus foliaceis ovario oblongo æquilongis. Mouna Kea, Hawaii. This and the preceding are doubtless related to Chamisso's Lobelia calycina, ambigua, and pinnatifida,— obscure species, referred by Presl and De Candolle to Delissea, but by their foliaceous calyx-lobes apparently effecting a transition to Cyanea. The next species, of which materials are also incomplete, is equally ambiguous.

4. CYANEA? ROLLANDIA (Rollandia crispa, Gaud. Lobelia calycina, Cham.?): fruticosa; foliis sesqui- tripedalibus obovato-lanceolatis inferne longe attenuatis breviter petiolatis membranaceis fere glabris margine serrulatis undulatis vel integerrimis; pedunculo petiolum adæquante superne bracteato paucifloro; floribus cinereo-uberulis; calycis lobis oblongis seu lanceolatis foliaceis ovario æquilongis; corolla sesquipollicari; fructu pyriformi pollicari. - Oahu.

5. CYANEA TRITOMANTHA (sp. nov.): caule simplici arborescente orgyali; foliis lato-lanceolatis membranaceis subintegerrimis fere glabris basi acutis tripedalibus (incl. petiolo crasso 5-8-pollicari); floribus "confertis" magnis; calyce pubescente, lobis linearibus pollicaribus foliaceis ovario cylindraceo longioribus; corolla tripollicari extus tomentoso-pubescente in segmentą 3 longo-linearia mox divisa.- Mouna Kea, Hawaii.

6. CYANEA SUPERBA, Lobelia superba, Cham. bus, Presl.-Oahu.

Macrochilus super

7. CYANEA LEPTOSTEGIA (sp. nov.): glabra; foliis ad apicem caulis simplicis arborei confertis lanceolatis subsessilibus integerrimis undulatis (bipedalibus et ultra); racemis brevissimis confertifloris; calycis segmentis prælongis e basi latiori angustissime linearibus patentibus corolla gracili longioribus persistentibus. - Upper edge of the forest near the tabular summit of Kauai. Calyx-lobes fully two inches long, and, except at their broader base, less than half a line wide!

Of Clermontia, Gaud., the specimens examined are reducible to two species, viz.:

1. CLERMONTIA GRANDIFLORA, Gaud., with its several varieties, Var. a. BREVIFOLIA (C. grandiflora, Gaud. Bot. Voy. Freyc. p. 459, t. 73): foliis membranaceis ovalibus leviter obovatis ovatisve utrinque angustatis vel acutatis modice serratis bi-tripollicaribus, petiolo gracili pollicari.-The flowers are evidently amplified or exaggerated on Gaudichaud's plate.

Var. B. OBLONGIFOLIA (C. persicafolia and C. oblongifolia, Gaud. 1. c. t. 71, 72): foliis oblongis seu elongato-oblongis sæpe obtusis deorsum attenuatis repando-serratis 4-6-pollicaribus, petiolo bi-tripollicari.

Var. y. LONGIFOLIA (C. grandiflora, Hook. & Arn. C. Kakeana, Meyen in Presl. Lob. C. macrophylla, Nutt. C. macrocarpa, Gaud. Bot. Voy. Bonite, t. 49. C. viridis, Gaud. ined. in herb. Mus. Par.): foliis subcoriaceis vel membranaceis oblongo-lanceolatis seu anguste oblongis creberrime serrulatis 3-9-pollicaribus basi in petiolum 1 – 2pollicarem attenuatis.

2. CLERMONTIA PARVIFLORA, Gaud. ined. (C. oblongifolia, Hook. & Arn., non Gaud. C. Byroni, pyrifolia, seu parviflora, Gaud. in herb. Mus. Par.): fruticosa, glabra; foliis membranaceis lanceolatovel subspathulato-oblongis breviter acuminatis crebre repando-serrulatis; pedunculo paucifloro pedicellisque brevibus petiolum haud superantibus; floribus vix pollicaribus gracilibus leviter curvatis "cæruleis"; calyce breviter 5-lobo corollam hinc alte fissam æquante. — Hawaii (and Oahu ?), first collected by Macrae:

There are three species of true, fleshy-frutescent Lobelias, viz. : — 1. LOBELIA MACROSTACHYS, Hook. & Arn. Bot. Beech. Voy. p. 88; Gaud. Bot. Voy. Bonite, t. 46.- Oahu and Hawaii. Gaudichaud's plate exhibits flower-buds only. These when fully formed are 14 to 2 inches long and mostly recurved; the developed corolla 2 or 3 inches long, "pale" or "white with the summit lilac."

2. LOBELIA GAUDICHAUDII, A. DC.; Gaud. 1. c. t. 45. · Oahu. Var. KAUAENSIS: racemo puberulo; calycis viscosi lobis brevioribus, i. e. tubo paullo longioribus. - Kauai. "Corolla pale, with pink veins."

3. LOBELIA NERIIFOLIA (sp. nov.): caule fruticoso crasso medulla farcto; foliis confertis elongato-linearibus utrinque angustatis in petiolum attenuatis coriaceis transverse venosis margine integerrimo revolu

tis supra glabris subtus incanis; racemo virgato densifloro; bracteis lobisque calycis subulato-setaceis; corolla rectiuscula cærulea. East Maui. Leaves a foot or less in length, only a third or half an inch long. Capsule dehiscent through the short and obtusely conical vertex. Scævolæ Polynesia. The collection contains,

1. SCEVOLA LOBELIA, Linn., De Vriese. Coast of all the coral islands, and of the Feejees, &c.

2. SCEVOLA SERICEA, Forst., of which S. plumerioides, Nutt., of the Sandwich Islands, is a variety with ample and almost glabrous leaves. Tonga, Samoan Islands, &c.

3. SCEVOLA CORIACEA (Nutt.): fruticosa, decumbens; axillis brevissime barbatis; foliis parvulis carnoso-crassis obovato-spathulatis in petiolum brevem attenuatis aveniis sæpe retusis; pedunculis axillaribus uni- (raro tri-) floris; calycis limbo truncato vel obscure quinquelobo; corollæ lobis lineari-lanceolatis, alis angustis. - Sandwich Islands. Var. a. (S. coriacea, Nutt. in Trans. Amer. Phil. Soc. n. ser. 8, p. 253) cinereo-puberula vel glabella; foliis integerrimis; corolla extus glabra vel pilosula, lobis intus piloso-barbatis. Kauai and Maui, on sand-hills.

Var. B. corolla intus imberbi extus foliisque glabris. — Nihau, Remy. Var. y. foliis cinereo-tomentulosis apice 3-5-denticulatis; corolla extus pubescente, lobis intus glabris. - Molokai, Remy. To this species probably belongs the Sandwich Island specimen referred by De Vriese to S. montana, Labill. ; but that species is an upright shrub, with well-developed calyx-lobes.

4. SCEVOLA GAUDICHAUDI, Hook. & Arn. (non Gaudichaudiana, Cham.), includes S. montana, Gaud., non Labill., and apparently S. Menziesiana, var. glabra, Cham. It will probably prove to be only an extreme form of the following polymorphous species; but it has a less developed inflorescence, narrower and somewhat fleshy-thickened, nearly veinless, more entire, and smaller leaves, a more slender and usually glabrous corolla, &c. The flowers of this and the following species are white, not yellow as De Vriese implies. De Vriese's genus Temminckia, founded on these Sandwichian species, is said to differ from Scævola in the inflorescence not being cymose, nor the filaments bearded, nor the fruit fleshy (baccate). But it would be difficult to find a more purely cymose inflorescence than in these species whenever the peduncle is several-flowered; the filaments are equally beardless in the original and perhaps in every known species of Scævola, and the mature fruit is a baccate drupe.

5. SCEVOLA CHAMISSONIANA, Gaud. (a form with pubescent corolla), Hook. & Arn., Cham. (corolla, &c. glabrous), clearly includes S. Menziesiana, Cham. (excl. var.), a small-leaved form, either glabrous or pubescent; S. ciliata, G. Don; S. ligustrifolia, Nutt. 1. c. (a form with small and almost entire leaves); S. pubescens, Nutt. 1. c.; S. pu bescens, Gaud. in the Paris herb. (with the younger leaves beneath and the inflorescence softly pubescent, the corolla externally pubescent); S. intermedia, Gaud. 1. c. (with the corolla and the lanceolate nearly entire leaves glabrous); S. Dielliana, Gaud. 1. c., with larger, puberulent, and sparingly serrate leaves, the peduncle elongated. All are forms of one species, which has more veiny and toothed leaves than the foregoing, mostly slender and often several-flowered peduncles, and broader, broadly wing-margined lobes to the corolla.

6. SCEVOLA MOLLIS, Hook. & Arn., of Oahu, also on Kauai with the leaves not so downy, is well marked by the soft and dense canescent pubescence or close tomentum of the lower surface of the large, oblonglanceolate leaves, short-peduncled inflorescence, and outside of the corolla. The latter has not a particularly long tube, nor are its lobes unusually pointed.

7. SCEVOLA (CAMPHUSIA, De Vr.) GLABRA, Hook. & Arn. The limb of the more or less curved yellow corolla is nearly equally fivecleft, although some of the lobes are apt to be conglutinate; and the anthers are normal for the genus. The connective is similarly produced in the following species, and, as figured by Labillardiere, in S.

montana.

8. SCEVOLA FLORIBUNDA (sp. nov.): fruticosa, orgyalis; ramis puberulis mox glabratis, axillis vix barbatis; foliis lanceolato-oblongis subspathulatis submembranaceis repando-dentatis obscure penninerviis glabris basi attenuata sessilibus vel subpetiolatis ; cymis multifloris ex axillis supremis et terminali thyrsum amplum efficientibus; calycis lobis ovatis oblongisve ovario brevioribus; corolla extus incana, lobis intus glabris oblongis; stylo glabro; indusio ciliato extus piloso.- Feejee Islands, where it was also collected by Professor Harvey.

Of Campanulaceae the only thing of interest is

WAHLENBERGIA PERUVIANA (sp. nov.): hirtella, humilis; caulibus ramosis diffusis; ramis usque ad apicem foliosis; foliis alternis parvis spathulatis subintegerrimis sessilibus, summis florem bracteantibus; calycis tubo hemisphærico hirsuto lobis oblongis brevioribus; corolla brevi-campanulata ultra medium quinquefida; capsula semisupera, parte libera conico trivalvi. - Andes of Peru above Baños.

3. Enumeration of a Collection of Dried Plants made by L. J. Xantus, at Cape San Lucas, &c. in Lower California, between August, 1859, and February, 1860, and communicated to the Smithsonian Institution. By ASA GRAY.

Such scanty knowledge as we have hitherto possessed of the botany of Lower or Peninsular California was nearly all supplied by the notes and hasty collection made by the late Mr. Hinds, in the voyage of the British surveying ship Sulphur, which touched at the Bay of Magdalena, Cape San Lucas, &c., late in the autumn of 1839. These notes, and an account of the collection, with descriptions of the new species by Mr. Bentham, were published in the Botany of the Voyage of the Sulphur, in 1844. The present collection was made by the indefatigable Mr. Xantus, at San Lucas and the vicinity, while in the employment of the U. S. Coast Survey in charge of a station for tidal observations. Small as this collection is, it contains not a few novelties, and I trust is an earnest of many more. Where the coast furnishes so large a percentage of new species, the interior, and especially its mountains, may be expected to yield a richer harvest to future explorers. Mr. Xantus has already made one successful visit to the mountains within his reach, with very interesting zoological results. At the same time he made a good botanical collection, which has most unfortunately been lost.

The numbers in the ensuing list are those under which the specimens have been distributed, as far as the extent of the collection allowed, among leading herbaria, the full set being reserved for the national collection in charge of the Smithsonian Institution.
