LEGUMINOSiE. 33 



37. T. Grayi, Loja. Giorn. Bot. Ital. xv. 189 (1883) : T. barbigerum, 

 var. Andrewtiii, Gray, Proc. Am. Acad. vii. 335 (1868). Erect, stout, with 

 long internodes, 1 — 2 ft. high, sparingly branched, villous •with long 

 spreading hairs : leaflets 1 in. long, cuneate-oblong or elliptic-lanceolate, 

 obtuse or acutish, sharply serrulate : heads long-peduncled, 1 in. broad ; 

 the involucre as broad : calyx-tube scarious, villous, 10-nerved ; teeth 

 linear-subulate from a triangiTlar base, plumose, as long as the dark red- 

 purple corolla. — First collected by Lr. Andretcs (1856) ; later, at Mendo- 

 cino City, Bolander ; also in Marin Co., Mrs. Curran. A fine species ; 

 not at all susceptible of being referred to T. barbigerum as a variety. 



38. T. fiicatuiii, Liudl. Bot. Eeg. t. 1883 (1836). Usually stout and 

 fistulous, the decumbent branches 1 — 2 ft. long ; herbage light green, 

 glabrous and somewhat succulent : stipules large, membranaceous, nearly 

 or quite entire : leaflets H^l^o in. long, broadly obovate, obtuse or retuse, 

 dentate or spinulose-denticulate : peduncles stout, far exceeding the 

 leaves ; bracts of the involucre ovate-lanceolate, acuminate, scarious- 

 margined, connate at base : heads hemisjjherical, 1 — 2 in. broad : calyx 

 thin, campanulate, the short teeth entire, unequal : corolla Jg — 1 in. long, 

 ochroleucous, fading with a red tinge : pod stipitate, 3 — 8-seeded : seed 

 roundish, nearly 1 line broad, minutely granulate. — Common along 

 the coast and in the interior. Variable in size ; often small and few- 

 flowered. 



39. T. ainpleeteiis, T. & G. Fl. i. 319 (1838) ; H. & A. Bot. Beech. 330. 

 t. 78 (1840) : T. <iuercelorum, Greene, Pitt. i. 172 (1888). Light green and 

 glabrous like the last, but small, slender, the branches 3—10 in. long : 

 leaflets %~-fi in. long, cuneate-obovate or -oblong, truncate or retuse, 

 mucronately denticulate : peduncles slender, not surpassing the leaves : 

 involucre half as broad as the heads, its lobes broad, scarious-margined. 

 obtuse, sometimes cleft or toothed : calyx cleft nearly to the base, the 

 subulate slenderly acuminate teeth very unequal, the larger rarely toothed 

 or cleft : corolla ochroleucous, 2—3 lines long : pod membranaceous, 

 translucent, finely reticulate with green veins, promptly dehiscent by one 

 suture only, 4 6-seeded : seed small, transversely oval, emarginate at 

 the hilum, coarsely tuberculate-rugose. — Not common ; but found at 

 Monterey, Louglas, Oakland Hills, Chesnut, Simonds, Alameda, Greene ; 

 plentiful on moist flats about Byron Springs. The type, collected by 

 Douglas, is exactly this ; and it is more allied to T. fucahnn than to any 

 of the following very common plants, two or more of which have long 

 been confused with it. 



40. T. diversifolium, Nutt. PI. Gamb. 152 (1848) ; Greene, Pitt. i. 7. 

 Diffuse, glabroiis, the branches flaccid though not very slender. 1-2 ft. 

 long : stipules ovate, entire, subulate-pointed ; leaflets linear or oblong, 

 obtuse or truncate, repandiy dentate or somewhat serrulate, 1 in. long :
