Dr. Torrey, in making the rectification, proposes to call Newberrya, in honor of the distinguished vegetable paleontologist and geologist who discovered it. The principal differences between these two genera appear in the subjoined synopsis. That of the seven genera of the group, all but the Linnæan one should rest upon single species, is not altogether satisfactory to contemplate; but their characters are so marked that it does not seem possible to combine any two of them.*

DOUGLASIA MONTANA: subglabra; foliis secus ramos imbricatis subulato-linearibus acutiusculis glabris ciliolatis; floribus plerisque solitariis; calyce basi vix truncato unibracteato, segmentis acutissimis tubo paullo longioribus corollae tubum adæquantibus. Rocky Mountains, Montana Terr., Winslow J. Howard, M. A. Brown. Nearer to D. arctica than to D. nivalis. To Douglasia belongs Gregoria, Duby, apparently founded in the same year, Lindley referring to Brande's Journal of January, 1828, for his original character of Douglasia. But it is really in the volume for 1827, which gives this name a clear priority.

PRIMULA SUFFRUTESCENS: cæspitosa, glabra; caudicibus elongatis humifusis incrassatis sublignosis; foliis confertissimis spathulato-cuneatis basi longe attenuatis apice 5 – 9-dentatis crassis fere aveniis; scapo foliis 2-3-plo longiore 3-7-floro; involucri foliolis lineari-subulatis pedicellis brevioribus; calyce minutim glanduloso (cum pedicellis), segmentis lato- seu ovato-lanceolatis tubo brevissimo duplo longioribus corollæ rubro-purpureæ tubo subdimidio brevioribus; lobis corollæ leviter obcordatis. — California, Lobb, in herb. Hook. Sierra Nevada, on Silver Mountain, alt. 10,500, near the snow, Brewer. Leaves about an inch long, resembling those of Saxifraga cuneifolia, but narrower and thicker. Lobes of the calyx varying from lanceolate to almost ovate. Corolla about half an inch long.

PLANTAGO HIRTELLA, HBK., var. CALIFORNICA (P. Urvillei, var. Californica, Fisch.), occurs along the coast at Monterey and San Francisco, and, more interior, at Los Angelos (Dr. Peckham). It accords very well with Fendler's Pl. Venez. No. 768, and perhaps was introduced into California.

PHELIPEA TUBEROSA: nana, superne pruinoso-puberula; caule basi tuberoso-incrassato squamis strobilaceis imbricantibus tecto superne breviter confertissime ramoso densifloro; calyce bibracteolato profunde inæqualiter 5-fido (-inubus 2 anticis fere ad basim usque, lateralibus et posticis ultra medium extensis), segmentis æquilongis lanceolatis corolla lutescente tubulosa paullo brevioribus; antheris glabris vel ad suturas parce lanigeris.-On a high and dry ridge of the Gavilan Mountains, in sandy soil, Brewer. A span or less in height; the much-crowded flowers barely half an inch in length. Nearly related to

PHELIPÆA PINETORUM (Orobanche pinetorum, Geyer in Hook. Kew Jour. Bot. 3, p. 297): caule ramisque pubescentibus; squamis inferioribus angustioribus; calyce vix ad medium æqualiter 5-fido, lobis subulatis. Char. from fructiferous specimen collected in the valley of the Columbia by Dr. Lyall, comm. Royal Gardens, Kew.

PHELIPEA ERIANTHERA, Engelm. MSS. (Orobanche multiflora Nutt. Pl. Gamb. p. 179, ex char.): P. Ludoviciana peraffinis; floribus majoribus; antheris crassioribus maxime lanigeris; calycis segmentis vulgo gracilioribus. - New Mexico, Fendler (585), Wright (1449, anthers less woolly), J. M. Bigelow, Parry (147, coll. 1867); Pachitiga, Chihuahua, Thurber, cited in Bot. Mex. Bound. Survey as P. Ludoviciana. Apparently a quite distinct species, but the woolliness of the anthers must not be too implicitly relied on.

* ANTIRRHINUM, Tourn.

On a survey of our North American species, which in California are now rather numerous, it seems inevitable that Antirrhinum should include the personate species of Maurandia, also Nuttall's Gambelia. propose the following arrangement: —

I

§ 1. ORONTIUM, Benth. I have seen no indigenous species.

A. CYATHIFERUM, Benth., by the description, and still more by the figure, has a rather prominent palate to the ringent corolla.

A. CONFERTIFLORUM, Benth., from Coulter's collection, I suspect to be Mohavea viscida, which is No. 616, in fruit only, in Coulter's Californian collection.

§ 2. SÆRORHINUM.

Corolla palato prominente extruso faucem haud vel vix claudente. Filamenta apice pl. m. dilatata. Capsula inæqualis. Semina Antirrhinastri. - Herbæ annuæ, Californicæ, plerumque alternifoliæ, nunc strictæ, nunc diffusæ et ramulos filiformes sæpe prehensiles proferentes. Pedicelli breves vel subnulli. Flores sæpissime parvi.

A. glandulosum and A. Virga are the species in which the palate is most appressed to the upper lip. In the diffuse species the corolla more and more approaches that of the following section. Their slender branchlets, mostly produced from the same axil with a flower, are evidently sensitive to contact in the same manner as the petioles and peduncles of Maurandia. In specimens of A. vagans and A. Breweri they are not rarely found with one or two close turns around some slender object, and the coil thickened and hardened in the manner of most petiole-climbers. The similar twining branches of the erect and spicate A. Coulterianum have been noticed by Dr. Parry or Prof. Thurber. A case of special interest, as a step in the transition from leafy branch to tendril, occurring in a genus of which some species do not climb at all, while others climb by tendril-like petioles and peduncles.

* Axilliflora; axillis fere a basi ad apicem caulium simplicium vel basi simpliciter ramosorum floriferis sine ramulo. Folia oblongo-linearia, obtusa, subpetiolata, conformia, flores parvos brevissime pedicellatos plerumque superantia. Calyx subæqualis, segmentis linearibus. Capsula stylo rigido subulato superata. Caulis erectus, strictus.

ANTIRRHINUM CORNUTUM, Benth. Pl, Hartw.: viscoso-villosum, subglandulosum; caule subpedali basi ramoso; corollæ tubo calyce labiisque suis longioribus, sacco prominente scrotiformi; filamentis omnibus apice oblique obovato-dilatatis; stylo capsula parum longiore; seminibus echinulato-favosis. Known as yet only from Hartweg's No. 1888, from the valley of the Sacramento.

ANTIRRHINUM LEPTALEUM: viscoso-villosum, fere eglandulosum; caule sesquipedali simplicissimo vel basi parce ramoso; corollæ ut videtur alba tubo calycem vix superante labiis (superiori alte bifido) subæquilongo, lobis fere æqualibus obovatis leviter eroso-crenulatis, sacco angusto scrotiformi; filamentis longioribus apice oblique obovatodilatatis, brevioribus vix dilatatis; stylo capsulæ subæquilongo; seminibus rugoso-foveolatis. Mariposa Co., at Clark's Ranch, Bolander. Flowers shorter and more crowded than in A. cornutum; the tube only 2 or 2 lines long. Leaves at most an inch long.

* Spicata; floribus folia floralia diminuta superantibus densius spicatis. Folia angusta, pleraque sessilia. Caules erecti ramosi, in sp. ultima ramulis prehensilibus instructi.

ANTIRRHINUM VIRGA: glaberrimum; caule simplicissimo stricto (ultrabipedali); foliis caulinis angustissime linearibus suberectis (imis ignotis), floralibus parvis subulato-setaceis calycem adæquantibus ; racemo spiciformi virgato densifloro (subpedali); floribus secundis mox horizontalibus; corollæ tubo labiis calycisque segmentis vix inæqualibus ex ovato-lanceolata subulatis duplo longioribus, sacco mammæformi, palato barbulato, lobis brevissimis; filamentis viscoso-hirsutis, longioribus præsertim apice dilatato anthera latioribus. California, No. 191, in collection of the late Thomas Bridges, distributed by the Smithsonian Institution. Lowest leaves of the specimen about 13 inches long, barely a line wide, tapering upwards. Corolla seemingly white or whitish, half an inch long, the tube cylindrical. The fruit of this very peculiar species not seen.

ANTIRRHINUM GLANDULOSUM, Lindl.: elatum, undique pilis glandulosis viscosissimum, late ramosum; foliis lanceolatis, floralibus flore paullo brevioribus, racemo spiciformi itaque folioso; corollæ roseæ tubo

lato labiis æquilongis calycisque segmentis inæqualibus lato-lanceolatis paullo longioribus; filamentis conformibus sursum leviter dilatatis; stylo longo; seminibus fimbrillato-favosis. Apparently very common around Santa Barbara, Santa Cruz, Santa Clara, &c. No filiform branches accompanying the flowers; these over half an inch in length.

ANTIRRHINUM COULTERIANUM, Benth. caule gracili 2 – 4-pedali glaberrimo erecto vel ope ramorum prehensilium sustento; foliis glabris linearibus vel inferioribus oblongis subpetiolatis, floralibus minutis ; racemo spiciformi conferto viscoso-piloso sæpius glanduloso; corollæ tubo calycis segmentis paullo longiori, sacco mammæformi magno, labio inferiori maximo tubo duplo longiori, superiori parvo patentissimo bifido; filamentis sursum dilatatis; stylo persistente capsula dimidio breviore; seminibus foveolatis. Found only in the southern part of California. "Stem supporting itself on other plants by its twining slender branches." Some of these appear in the raceme, from the same axils with the lower flowers, are tendril-like, flexuous or spirally incurved; the minute leaves at their apex also recurved, forming hooks.

* Axilli-ramulosa; floribus secus ramos diffusos sparsis, axillis floriferis sub flore sæpius ramulo filiformi nunc tortili prehensili instructis. Folia petiolata, flore plerumque longiora. Calyx inæqualis, sepalo postico majore.

← Pedunculi calyce longiores: filamenta sursum sensim dilatata. ANTIRRHINUM NUTTALLIANUM, Benth.: viscoso-pubescens; foliis ovatis imisve subcordatis, floralibus superioribus flore brevioribus ; calycis segmentis subovatis, postico fere enervi cæteris modice majoribus tubo corollæ violacea paullo brevioribus; labiis tubo longioribus, superiore suberecto emarginato-bilobo palatum adæquante; seminibus longitudinaliter undulato-costatis. (Sairocarpus Californicus, Nutt., in herb.) Collected apparently only near San Diego and Los Angeles, by Coulter, Nuttall, Wallace, and Dr. Cooper. Flower 4 or 5 lines long.

← ← Pedunculi calyce breviores: filamenta apice oblique spathulato-dilatato. Calyx pilis longis laxis hirsutus.

ANTIRRHINUM BREWERI: tenuiter viscoso-pubescens; ramis gracillimis dissite floriferis; foliis ovato- seu oblongo-lanceolatis obtusiusculis, superioribus retusis, summis flore brevioribus; calycis segmentis linearibus seu lineari-lanceolatis, postico parum latiori tubo corollæ paullo breviori subuninervi; corollæ pallide violacea, labio superiori
