48 DKUPACE^. 



leaves crowded ; leaflets 14—^4 in. long, oblanceolate, acute, entire, some- 

 what silky when young : fl. near the ends of the stiff spinescent branchlets, 

 on short 2-bracteolate peduncles, from pale rose- to deep red-purple, aboui 

 % in. long. — At middle elevations in the Coast Range ; often forming 

 impenetrable thickets on hill-sides and summits ; the flowers very- 

 beautiful. Apr. — June. 



18. THERMOPSIS, Roherl Brown (False Lupine). Stout erect 

 perennial herbs with palmately 3-foliolate leaves, foliaceous stipules, and 

 a terminal raceme of yellow flowers ; the pedicels subtended by persistent 

 bracts. Calyx eampanulate, cleft to the middle, the two upper teeth often 

 united. Banner roundish, shorter than the wings, the sides reflexed ; 

 keel nearly straight, obtuse, equalling the wings. Stamens distinct. Pod 

 long, linear, flat, several-seeded. — An Asian and West Axaerican genus 

 analogous to Bapiisia of the Atlantic slope, but very distinct. 



1. T. macrophylla, H. & A. Bot, Beech. 329 (1840). Stipules ovate, 1 in. 

 long or more ; leaflets elliptic-oblong, acute at each end, 4 in. long, villous- 

 tomentose beneath, nearly glabrous above : pod straight, nearly erect, 

 4 — 5-seeded. — An obscure and little known plant (unless the next be spe- 

 cifically the same), collected by Douglas probably near Monterey, and at a 

 comparatively recent date (1876) by Mr. Joseph Clarke in Mendocino Co. 



2. T. Californica, Wats. Proc. Am. Acad. xi. 126 (1876). Stipules 

 broadly lanceolate, less than 1 in. long ; leaflets obovate or oblanceolate, 

 1 — 2 in. long, silky-tomentose on both faces : pod 6— 8-seeded. — Common 

 on low hills in Marin, Sonoma and Napa counties ; also southward. May. 



Order n. DRUPACE/E. 



DeOandoUe, Flore Frangaise, iv. 479 (1805). 



Shrubs or trees with bark exuding gum ; bark, leaves and seeds more 

 or less keenly bitter (containing hydrocyanic acid). Leaves alternate, 

 simple, with small caducous stipules. Flowers perfect (except in 

 N'uilallia), regular. Calyx tubular or eampanulate, free from the ovary, 

 the tube lined with a disk, deciduous ; limb 5-lobed, imbricate in aestiva- 

 tion. Petals 5, perigynous. Stamens about 20, inserted within the petals 

 on the disk of the calyx-tube. Pistil 1 (in Nuliallia 5) ; style simple ; 

 ovary 1-celled, 2-ovuled, becoming a drupe. Seed pendulous ; cotyledons 

 large, thick, fleshy ; albumen 0. — A small order, commonly appended to 

 Rosacese as a suborder ; nearly allied to Pomaceae, less intimately to 

 Eosacese proper ; of economic importance, on account of the fruits — 

 plums, cherries, almonds, etc. 



1. AMYGrDALUS, T/i^op/jras/ws (Almond-Tree). Leaves conduplicate 

 in the bud. Flowers solitary or in pairs, from lateral buds, appearing
