 leaves long-petiulud, pinnutidy divideil, the segments oval to linear and 2 to 12 lines 

 long ; upper leaves sessile, the segments usually narrow : Mowers scarlet to orange, 

 the petals 2 to 12 lines long ; peduncles elongated : capsules smooth, obovate-oblong 

 or top-shaped, truncate, narrowed below, G to 8 lines long, strongly ribbed ; tho 

 persistent style a line long. - Trans, llort. Soc. 2 ser. : i. 408. Hook. Ic. PI. t. 

 272. M. crassifolia, Benth. 1. c. 



A veiy variable species, in dry soils tVom San Diego to Clear Lake, flowering in early sununer. 



7. DENDROMECON, Iknth. 



Sepals 2. Petals 4. Stamens numerous, with short filiform filaments and linear 

 anthei-s. Ovary linear, with 2 nerve-like placentas : stylo short : stigmas 2, short 

 and erect. Capsule linear, nerved, 1-celled, dehiscent the whole length by 2 valves 

 separating from the placental ribs, many-seeiled. Seeds oblong or globose, finely 

 pitted, carunculate. — A smooth branching shrub ; with alternate vertical entire thick 

 and rigid leaves, and showy yellow flowers. The only truly woody plant belong- 

 ing to the order. 



1. D. rigidum, Bentli. A shrub 2 to 8 feet high, with many slender branches 

 and whitish bark : leaves ovate to linear-lanceolate, 1 to 3 inches long, very acute 

 or mucronate, sessile or nearly so, twisted ui)on the base so as to become vertical, 

 reticulately veined, the margin rough or denticulate : flowers bright yellow, 1 to 3 

 inches in diameter, on pedicels 1 to 4 inches long : capsules curved, attenuate above 

 into the short stout style, \\ to 2\ inches long: seeds large, 1^ lines long. —

Dry rocky liills of the Coast Ranges from San Diego to Clear Lake, most abundant south of 

 Point Concejition ; Santa Kosa Island, Harford. Vi-ry variable in its foliage and in the size of 

 the flowers, but uU the forms seem rcferabio to a single s|)ecies. 



8. ESCHSCHOLTZIA, Cham. 



Sepals coherent into a narrow pointed hood, deciduous from within a dilated top- 

 shaped torus. Petals 4. Stamens numerous, with short fdaments and linear 

 anthers. Ovary linear, with 2 nei've-like placentas : style very short : stigmas 

 divided into 4 to (> linear unequal divergent lobes. Capsules elongated, strongly 

 lO-nerved, 1-celled, dehi.scent the whole length by 2 valves separating from the 

 placental ribs, many-seeded. Seeds globose, reticulate or rough-tuberculate. — 

 Smooth glaucous slender annuals ; with colorless bitter juice, fimdy dissected alter- 

 nate petioled leaves, and bright orange or yellow flowers. 



The very variable Califomian plant, first collected by Chamisso, and published by him in 

 1820, has since been described under numerous names, and has usually been considered as afford- 

 ing basis for 4 or 5 or more distinct Hi)ecies ; but the differences in habit, foliage, and flowers 

 seem to be of too little moment or too inconstant for a recognition of more than varieties among 

 tho various forms. There are indications, however, that the seeds may allbrd charactors \ipon 

 which some of the following varieties may bo re-established as species. Mature fruiting speci- 

 mens are at present too rare in our collections to permit a positive detennination of the question. 



1. E, Californica, Cham. Usually 1 to 1| feet high and rather stout, branch- 

 ing : flowers large, 2 to 4 inches in diameter, usually brilliant orange in the centre ; 

 torus dilated and often broadly rimmed : capsule 2^ inches long, curved : seeds two 

 thirds of a line in diameter, reticulated ; rhaphe obscure. — Hor. Phys. Berol. 73,
