NEW BOTANICAL SPECIES FROM S. CALIFORNIA 



A. I).\vii>s,,x. M.I). 



Langloisia Flaviflora n. sp. how matted, shortly branching, dark 

 green, spinesceiil iiumial about r. cm. high; foliage glandiilnr pubes- 

 cent; leaves sessile, strap shaped, 15-25 mm. long, '.) nun. wide, 

 sli.silitly narrower at the apex, leaves edged with 10 or more tri- 

 angular based white spines mostly crowded towards the base; apex 

 of the leaf triangular and spine tipped with 2 similar spines at 

 the side; flowers light yellow, sessile, 10 mm. long; calyx split 

 almost to the base slightly accrescent, its segments 5 mm. long, 

 spine tipped; corolla tube white, cylindrical, 5 mm. long, 1 mm. 

 wide; throat yellow; limb strongly bilabiate, pale yellow, its seg- 

 ments 5 mm. long. 1 mm. wide; stamens exserted 2 mm. beyond 

 the throat; pistil equalling the calyx; seed pod pyriform, 6-seeded. 



Type No. 3506. On sandy roadside. Willow Springs, Mohave 

 Desert, Kern Co., May 28, 1922. 



In habit of growth this plant closely resembles L. Matthewsli 

 but is smaller, less pubescent, with leaves somewhat similar, but with 

 a totally different flower, that of^L. Matthewsli being a mottled pink 

 — the limb measuring 10 mm. in length. The style in the latter is 

 much exserted. 



Allium Tenellum n. sp. Bulb without definite reticulation; stem 

 10-15 cm. high; leaves 2, shorter than the stem; pedicels 15-25, 10 

 mm. long; flower pinkish, open, the segments not overlapping; peri- 

 anth segments thin, lanceolate, acute, 6 mm. by 3 mm., the outer with 

 a greenish median stripe, the inner slightly narrower without the 

 stripe; stamens nearly equaling the perianth, anthers pink; filaments 

 linear; pistil 5 mm. long; stigma slightly 3-cleft; ovary with 6 flat 

 triangular crests in pairs wath the straight sides of the triangles edge 

 to edge. In fruit the outer pedicels are declined and curved. Type 

 No. 3524 Julian. San Diego Co., collected by Mrs. J. H. Bullard, 

 May, 1922. 



This adds another to the group of Alliums having 3-split stigmas. 

 Brewer and Watson in Bot. Cal. recorded only A. Parry i and A. flm- 

 brlatum as having this distinction. Jepson in his Flora of Cal. has 

 entirely omitted all reference to the nature of the stigma in all our 

 southern species. The shape of the stigma is probably a stable fac- 

 tor of diagnostic import. In southern Cal. we have A. Parry! ; A. flnr 

 briatum; A. Kresslerl; A. tenellum; A. montigenum; and A. peninsu- 

 lare, with 3-cleft stigmas. 



The latter two are somewhat alike. A. montigenum is lighter in 

 color with narrower petals that do not form an inner cup as accurately 

 described bj' Jepson. The chief difference is in the fruit. In A. pen- 

 insulare as we have it here, the ovary is crowned by a low continuous
