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. pubescens, 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.

1. ARGEMONE MEXICANA, Linn.

2. LYROCARPA COULTERI, Hook. & Harv. in Lond. Jour. Bot. 4, p. 76, t. 4. - Radix annua. Folia inferiora cordato-oblonga, repanda,

petiolo longo submarginato, superiora brevi-petiolata, dentata vel incisa. Petala latiora quam in exemp. Coulterianis, elongato-spathulata, rosea? post anthesin purpurascentia. Fructus haud maturus.

3. POLYGALA XANTI (sp. nov.): nana, cinereo-pubescens; caulibus adscendentibus e caudice perenni usque ad racemum densiflorum foliosis; foliis ovalibus subaveniis breviter petiolatis; floribus (majusculis) mox recurvis; pedicellis bractea sepalisque angustis æquilongis; alis ovali-oblongis; carina imberbi; fructu ovato sinu profundo emarginato 20

3. POLYGALA PUBERULA, Gray, Pl. Wright. 1, p. 40; floribus minoribus.

4. IONIDIUM FRUTICULOSUM (Benth. Bot. Voy. Sulph. p. 6, t. 2): var. DENTATUM: caulibus herbaceis 9-pollicaribus; foliis lanceolatis seu linearibus, majoribus argutissime dentatis. This must belong to Bentham's I. fruticulosum, a bad name; for in our plant the stems are wholly herbaceous, and I am not sure that the indurated and stout root is really perennial. The leaves vary from linear to broadly lanceolate, and the larger ones especially are beset with sharp salient teeth. The short peduncles, flowers, &c., accord with the published character and figure.

Sulph. p. 17? non Camb. rower than in the figure above cited, and the small intermediate lobes of the petals are three instead of four; otherwise there is no obvious difference, and No. 698 of Coulter's Mexican collection (from Zimapan) is intermediate in appearance. Without examining the petals the plant might naturally be taken, as I suppose it was by Bentham, for a Spergularia.

10. SPHÆRALCEA INCANA, Torr. in Gray, Fl. Fendl. p. 23, & Bot. Mex. Bound. p. 39. One of the less canescent forms.

11. HIBISCUS (BOMBICELLA) RIBIFOLIUS (sp. nov.): fruticosus, humilis, fere glaber; stipulis setaceis persistentibus; foliis rotundatis subcordatis crenato-dentatis sæpe trilobis chartaceo-membranaceis venulis reticulatis; pedunculis axillaribus unifloris folio longioribus sub apice articulatis; involucello 8-9-phyllo, phyllis lineari-setaceis calycis lacinias ovato-lanceolatas subsuperantibus corolla (purpurea?) triplo brevioribus capsulam subglobosam æquantibus; seminibus in loculis

plurimis laxe crinitis.

Caulis subpedalis. Folia semi-sesquipollicaria. Corolla sesquipollicaris. Most allied perhaps to H. phoeniceus; but the leaves are all rounded and obtuse, mostly lobed, and resembling those of a Ribes, the corolla much exceeding the calyx and involucel, &c. The young stems and petioles are slightly pubescent; the leaves perfectly glabrous.

12. GOSSYPIUM, foliis omnibus integris cordato-ovatis, Benth. 1. c. Like the specimens noticed by Bentham from the same district, destitute of fruit. The leaves of one specimen, however, begin to show lobes. It is probably a cultivated Cotton run wild.

13. MELOCHIA TOMENTOSA, Linn. "A common West Indian and Central American species, of which this is probably the northern limit."

14. KALLSTREMIA GRANDIFLORA, Torr. in Pl. Wright. 1, p. 28: var. DETONSA, Gray.

15. GALPHIMIA ANGUSTIFOLIA, Benth. Bot. Voy. Sulph. p. 9, t. 5. Apparently G. linifolia, Gray, Gen. Ill., is the same species, which extends across the continent on the southern border of the U. S. 16. KARWINSKIA HUMBOLDTIANA, Zucc.; Gray, Pl. Wright. 1, p. 32. ( = Berland. coll. no. 820, 889, 689, 906, 2340, 2359, 1230, &c.)

17. MAYTENUS PHYLLANTHOIDES, Benth. Bot. Voy. Sulph. p. 54. This has also been found on the eastern side of the continent, on the lower part of the Rio Grande, and at Key West.

18. CARDIOSPERMUM MOLLE, H. B. K.? A single specimen without fruit.

19. CARDIOSPERMUM? sp. nov. A shrubby species, with the habit of Bentham's Cardiospermum tortuosum, from the same district, but wholly glabrous and with a different foliage; the fruit unknown, and therefore the genus uncertain.

20. DODONEA VISCOSA, Linn. ? Destitute of flowers or fruit.

21. BURSERA MICROPHYLLA (sp. nov.): foliolis 14-16-jugis cum imparri 2-3 lin. longis oblongo-linearibus seu oblongis obtusis sessilibus in rhachi superne marginata; pedunculis 2-3-floris brevibus. (In Sierras Tulè, Sonora, leg. A. Schott, ex herb. Torr.) Frutex rigidus. Folia ad apicem ramulorum brevissimorum conferta. Flores hermaphroditi, an polygami? Petala 5. Stamina 10. Discus 5-lobus. Ovula ex cl. Torrey in loculis solitaria suspensa. Cotyledones contortuplicatissima. — Mr. Schott collected this with a few flowers and young fruit. Mr. Xantus, with fruit only, which is that of a Bursera.

22. DALEA CHRYSORHIZA (sp. nov.): pilosula; caulibus perplurimis e radice annua? filiformibus procumbenti-diffusis; foliolis 7-10jugis parvis (sesquilineam longis) obovato-linearibus emarginatis subtus nigro-glandulosis; stipulis minimis; pedunculis folia superantibus apice capitato-plurifloris; calycis pubescens dentibus oblongo-linearibus obtusis tubo fere æquilongis. — Radix perpendicularis, ut videtur annua, cortice aurantiaco. Caules pedales et ultra, tenues, parce pilosuli. Spica breves circiter 12-floræ; rhachi inter flores glandulis? singularibus fusiformibus acutis obsita. Calyx inter costas glandulosus, lobis cum bractea ovata calyce breviori foliaceis glandula acuta apiculatis. Corolla brevis, violacea. Legumen pilosulum. A well-marked species of this large, prevailingly North Mexican genus.

23. PHASEOLUS FILIFORMIS, Benth. Bot. Voy. Sulph. p. 13. But the whole plant is puberulent. The root is certainly annual.

24. Phaseolus (MACROPTILIUM) ATROPURPUREUS, DC. Fl. Mex. Ic. ined., & Prodr. 2, p. 395; Torr. in Mex. Bound. Surv. 2, p. 50; var. SERICEUS. I do not possess any specimen of Dr. Torrey's P. atropurpureus, which, described as a new species, may well be identical with its homonyme of De Candolle. Our South California specimens are identical with those of Mr. Schott, from the Rio Grande, dubiously appended to this species by Dr. Torrey, only they are for the most part still more silky-downy. The plant is of the section Macroptilium, but has a short calyx. The wings are deeply colored. The root is perennial.

25. COURSETIA? GLANDULOSA (sp. nov.): foliis ramisque glabratis, petiolo in setam desinente, foliolis ellipticis mucronatis; racemis sæpe fasciculatis sessilibus brevibus plurifloris cum calyce viscoso-glandulosis.

Rami tortuosi, nodosi, nascentes cinereo-villosi. Stipulæ setaceæ, persistentes. Foliola 7-9-juga, haud stipellata, petiolulata, 6-9 lin. longa, 3-4 lin. lata, parce appresso-puberula, mucrone conspicuo. Flores ex axillis foliorum annotinorum orti; racemi brevissimi sæpius bini vel terni; pedicelli conferti, 3 lin. longi. Bractæ parvæ, caducæ. Calyx ebracteolatus, breviter campanulatus, 5-fidus, pilis capitato-glandulosis viscosus; lobis triangulari-lanceolatis acutis, 2 superioribus paullo brevioribus et connatis. Corolla ut videtur pallide lutea; vexillum latissimum, emarginatum, basi biauriculatum, auriculis parvis; carina obtusa alis paullo breviori. Stamina diadelpha; antheræ conformes. Ovarium subsessile, lineare, glanduliferum, 10-12-ovulatum, continuum. Stylus gracilis a medio ad apicem subunilateraliter villosus: stigma capitatum. Legumen ignotum.
