very dwarf G. dichotoma, rlesirable for cultivation on account of its 

 abundaut and vaiiously colored flowers of comparatively large size for 

 the pygmy growth, the corolla being fully half an inch long, indeed 

 longer than the earlier stems. At the suggestion of Mr. Lemmou, this 

 dainty plant is dedicated to Mrs. Dr. Parry, one of the botanical party 

 who passed the last winter and spring in the San Bernardino district 

 ■ — making many interesting discoveries — and whose services to botany 

 well merit this recognition. 



G. BiFLORUS, Nutt. in herb. DC. ; Torr. 1. c. Chthamalia biJJora, Decaisne. 

 In this tlie corolla is rotate and deeply 5 cleft ; the corona tleeply lobed ; and 

 the canaliculate cre.st ailnate to each lobe is connected at base with the cobimn, 

 wliile it terminates above in tlie stout and conspicuous tliickened acumination 

 which incurves over the ed^e of tlie stigma. The follicles, as in the next, 

 are large and muricate. — Var. Wrightii, also from Eastern Te.xas, is a form 

 with the corolla almost 5-parted into narrower lobes, and the cusps of the 

 corona shorter. 



G. CYNANCiioiDES, Engelm. PL Lindh. i. 48. has the inflorescence much 

 inclined to be racemose-clustered on a peduncle-like summit of the stem, the 

 upper leaves being reduced and bract-like, the corolla rotatecampanulate and 

 almost 5 parted, and the very obtusely 5 lobed corona is appendaged within by 

 a shorter crest which terminates in a free and blunt apex, shorter than the lobo 

 to which it adheres. 



* * Caules Juimiles sed volubiles : fiores (luteoli) subsessiles solitarii, raro 



geinini : folia parva, pi. m. hastata. 



G. PARViFOLitrs, Torr. 1. c, excl. fruct. The corolla is globose in the bud, 

 deeply 5-lobed, and almost rotate when expanded, the lobes ovate. The fleshy 

 corona is at the very base of the short column; its lobes ovate, spreading, ap- 

 pendaged with a very broad adnate crest, the edge of which at base is united 

 with the column, at the apex extended into a minute iuflexed tooth. 



G. HASTur.ATUS. Litc/inostoma hastulatitm, Gray, Bot. Calif, i. G20. In this 

 the corolla is narrowly oblong in the bud, the lobes linear. The corona is of 

 distinct pieces, like the hoods of AsrJe/)ias, and, as in that genus, borne at the 

 summit of the colunm, close under the antliers ; tlie ligule or horn within 

 is prominently exserted and inflexed. Follicle rather slender and minutely 

 muricate. 



* * * Caules elongati subvolubiles : pedunculi axillares folio sagittato-cordato 



brcviores, unibellato 3-5-fiori : corolla oblongo-campanulata, lurida, inajus- 

 cula (J pollicaris), alte 6-fida, lobis lineari-obloiigis : corona cyatliiformis, 

 8ub-lobata, intus lamellis 5 columnae adnatis quasi septata. 



G. PRODOCTUS, Torr. 1. c. The follicles are ovate and smootli. The species 

 ranges from Western Texas to Arizona, and into adjacent parts of Mexico. 



* * * * Pedunculi filiformes folia mox longe superantes, quasi racemoso-pauci- 



flori : flores perpusilli: corolla rotata : corona alte lacuiiata, duplex : caulis 

 humilis, a basi ramosissimus, nee volubilis.
