11. STYLOPHORUM. Stamens 20 or more. Ovary in the genuine species with 3 or 4 

 nerviforin i)l:u'i'nt;« from wliich the valves of the capsule separate from apex to base. Style 

 comparatively long : stigmas 3, short and depressed, confluent. Seeds scrobiculate-reticu- 



■ lated : rhaphe prominent and crested. 



12. CHELIDONIUM. Stamens rather few. Ovary and capsule linear, strictly one-celled 

 with -2 nerviforni placentae, and a sliort style bearing two small simple stigmas: valves 

 membranaceous at nuiturity, deliiscent mostly from base upward. Seeds smooth : rhaphe 

 crested. 



13. GLAUCIUM. Like Chclkhnium, but mitre-shaped stigmas with divergent or deflexed 

 base on each side, and coriaceous capsule 2-celled by a spongy false partition between the 

 placentae, in which the scrobiculate seeds are partly embedded. 



Tribe III. HUNNEMANNLE. Leaves alternate, teniately decompound. Flowers 

 dimerous, i. e. sepals and placentfe 2, and (deciduous) jietals 4. Torus more or 

 less dilated and excavated under or around base of the pistil : flower thus as if 

 perigynous. Stamens numerous. Stigmas twice or thrice as many as placenta? : 

 ovary strictly one-celled. Capsule elongated and siliquiform, terete, striate- 

 costate, many-seeded, elastically '2-valved usually from the base to apex ; valves 

 coriaceous, the nerviforni placentre remaining attached to their margins, or im- 

 perfectly separating. Seeds globular, iuappendiculate. Juice of herbage mainly 

 watery and not acrid, of the root yellow. Flowers erect in the bud, in anthesis 

 usually more than one day, normally yellow. Consists of the adjacent Mexican 

 genus Hunnemannla, with calyx of distinct sepals and 4 roundish depressed 

 stigmas, the nerviform placenta? j)artly separating from the valves, and 



14. ESCHSCHOLTZIA. Torus under the flower dilated and hollowed, cyatliiform. 

 Calyx calyptrate, the two sepals completely combined into an extinguisher-shaped body, 

 which is detaclied at base and pushed off at the expansion of the 4 petals. Style short and 

 stout or harilly any : stigmas 4 to 6, subulate or setaceous, unequal. Cotyledons said to be 

 2-parted. Chiefly annuals

 stamen.) — Trans. Hort. Soc. ser. 2, i. 405 ; Benth. & Hook. Gen. i. ol. — Single 

 species, remarkable in the order on many accounts, among them for anthesis con- 

 tinued for several days, and marcescent petals at length loosely closing over the 

 forming fruit. 



P. CalifornicUS, Benth. 1. c. Low and slender annual, hispid with long spreading hairs, 

 or glabrate : leaves mainly opposite, closely sessile, ligulate-linear, obtuse, uervose : peduncles 

 a span or more long, sonretimes sca))ose : petals half inch or less long, from light yellow to 

 cream color or white (rarely roseate) : mature and separated carjiels linear, moniliform, 

 sometimes sparsely hispid, commonly glabrous. — Lindl. Bot. Keg. t. 1679; Sweet, Brit. Fl.

§ 1. Subscapo.se: capsule obovoid or clavate-ovoid, of rather firm texture, 

 crowned with the three broad and obtuse spreading introrsely stigmatose tips or 

 stigmas.
