448 SUPPLEMENT. 



Var. adscendens. A large and robust form (as sometimes in Mexico), rising a foot 

 or two high from the creeping base : branches freely racemosely flowered at summit ; the 

 upper and sometimes connate rounded leaves being much reduced and bracteiform. — 

 M. glabratus (chiefly), Gray, Bot. Mex. Bound, lie." M. Ilallii, Greene, Bull. Calif. Acad. 

 113, but species not truly annual, nor calyx-teeth acute. The specim^ of Hall described 

 from was a cultivated one. — Colorado and west to the Grand Cafion in N. W. Arizona, 

 south to Mexico. Comes nearest to the following. 

 ++ -H- Large-flowered for the size of the plant; the golden yellow and sometimes crimson-dotted 



corolla ample compared with the calyx, the lai-ger even an inch and a half long: capsule oval or 



slightly obovate, short-stipitate. 



M. luteus, L., p. 277. Exclude the syn. M. Scouleri, and from the var. aJpimts exclude the 

 syn. M. dentatus, Nutt. (which see above); and also M. cupreiis, Kegel {M. lufcus, var. 

 cuprea, Hook. Bot. Mag.), which belongs to a distinct Chilian species. The original Chilian 

 M. luteus, as Bentham decided, although usually distinguishable, cannot bo specifically sepa- 

 rated from the Northern coast form, M. giittafnii, J)C, Cat., and of Greene, 1. c, &c., to which 

 pertain M. luteus, Bot. Mag. t. 1501, Bot. Eep. t. 661, and Jacq. f. Eel. t. 92. The slender 

 shoots from the base of the stem either root and form stolons, or not rarely rise and bear 

 small leaves and flowers. 



Var. alpinus, Gray, p. 277 (excl. syn. as above). Includes a series of mountain 

 forms, varying from two inches to near a foot high, clearly perennial, proportionally large- 

 flowered. Small forms with round and nearly entire leaves answer exactly to M. TUingii, 

 Kegel, Gartenfl. xviii. 321, t. 631, plants of which, from the same sowing, developed next 

 year into the typical N. American species, shown in xix. 290, t. 665; also in the gardens 

 under this name and as " M . Razli," tlie latter answering to M. Tilingii, Greene, 1. c, from 

 near Summit Station. 



Var. depauperatus, Gray, 1. c. partly, il/. nilcrojilu/llus, Benth. ! in DC. Growing 

 with the larger or ordinary plants, evidently an extreme depauperate form, either seedling 

 or showing the creeping stolons ; with filiform stem 2 to 7 inclies high, 1-4-flowered ; leaves 

 a quarter-inch or so long, and corolla 6 or 7 lines long. Grows with the larger forms on 

 Columbia River: specimens exactly like those of Douglas from same district (except that 

 some show the stoloniferous base) were received from Mjs. Barrett. 

 M. Scouleri, Hook. Erect, from a stoloniferous base, a foot or two high : leaves thick, 

 very smooth and shining, oblong-lanceolate (an inch or two long, 4 to 6 lines wide), obtuse, 

 evenly callous-denticulate ; lower tapering into petioles of equal length ; floral ones short 

 and small, ovate and amplexicaul : flowei's apparently of the preceding, but corolla shorter. 

 — Fl. ii. 100; Benth. in DC. 1. c. — On the Columbia River, Scouler, in fruit only. Now 

 rediscovered, in flower, in the mud on the south shore of the river (sometimes covered at 

 high tide) about four miles above A.storia, by T. Meelian, probably near Scouler's original 

 station. 



-I— H— H— -)— -t— Pure annuals, leafy-slemmed, various in habit and size: no mucilaginous- 

 clammy hairs: seeds oval or oblong, mostly with a smooth close coat. 

 ++ Comparatively large-flowered, the 3'ellow corolla inch long and broad: upper cauline leaves 

 connate into orbicular disks, glaucf)us: calyx less oblique than in succeeding, 

 M. glaucescens, Greene. Erect, often tall, glabrous and glaucous, except the radical 

 and lower cauline leaves, which are sometimes villous-pubescent ; the.se cordate- orbicular, 

 crenate-dentate or incised, sometimes almost lyrate, slender-petioled ; the perfoliate disks 

 denticulate or entire : inflorescence at length racemiform : corolla with ample throat : style 

 minutely pubescent : calyx campanulate, slightly arachnoid-villous at the throat within, 

 appearing repand-truncate, the teeth being very short and broad, in fruit nodding on the 

 ascending peduncles, the two lower teeth incurving in the manner of the following. — Bull. 

 Calif. Acad. i. 113. — California, along streams in the foot-hills of the Sierra Nevada, from 

 Lassen to Butte Co., Fremont, Mrs. Austin, A. Graij. 



++ ++ Middle-sized to small-flowered (even in same species): herbage not glaucous : corolla yel- 

 low: calyx especially when fructiferous and ventricose oblique-sided and oblique at orifice, 

 strongly plaited-angled, mostly with acute or acutish teeth, the lower at maturity turned toward 

 the larger uppermost: fructiferous peduncles mostly spreading or the apex nodding: capsule 

 distinctly short-stipitate.
