f?2 Flora of the Patouse Regiort 



celled, with axile placenta: capsule 2-several-eelled, many-seeded; 

 endosperm fleshy. 



Ovary and capsule long and narrow. 



Capsule opening at the top by a hole left by the falling away of the base 



of the style: flowers all alike. 287. giThopsis. 



Capsule opening on the sides by 2 or 3 little valves which leave small 

 round perforations: flowers of two kinds. 



288. SPECULARIA. 

 Ovary and capsule short and broad or globular. 



Calyx-lobes broad: flowers of two kinds. 289. heterocodon. 



Calyx-lobes narrow: flowers all alike. 290. campanula. 



287. GITHOPSIS. 



L,ow annual herbs: flowers all alike: calyx with a 10-ribbed tube 

 and 5 long and narrow foliaceous lobes: corolla tubular-campanu- 

 late, 5-lobed: filaments short, dilated at the base: stigmas 3; ovary 

 3-celled: capsule strongly ribbed, crowned with the rigid calyx- 

 lobes about as long or longer, opening by a round orifice left by 

 the falling away of the base of the style; seeds very numerous. 



G. specularioides Nutt. Annual, erect, simple or branched from the 

 base, hirsute-pubescent throughout, 5-20 cm. high: leaves sessile, linear or 

 oblong, coarsely dentate, 3-12 mm. long: flowers terminal on the stem or 

 on axillary stout peduncles, erect: calyx-lobes linear, acuminate, glabrous 

 above, i-nerved, rigid, erect, as long as the narrowly-obconic tube: corolla 

 blue, barely exceeding the calyx-lobes. Very rare, bluffs of Snake River, 

 near Almota. 



288. SPECUIvARIA. 



Annuals: cauline leaves sessile or clasping: flowers blue or 

 purple, terminal or axillary, of two kinds, the earlier smaller, 

 close-fertilized, with a rudimentary corolla which never opens, with 

 mostly 3-4 calyx-lobes; the later with 5 calyx-lobes: corolla ro- 

 tate, 5-lobed: ovary 3 or sometimes 2-celled: capsule more or less 

 elongated, opening by 2-3 small lateral valves which leave round 

 or oval perforations, usually over partitions. 



S. perfoliata A. DC. Stems slender, erect, leafy, 20-40 cm. high, rough- 

 hairy on the angles: leaves orbicular, cordate, crenate, clasping at base, 1-2 

 cm. long, scabrous on the margins and veins: flowers of 2 sorts, the earlier 

 close-fertilized and with only rudimentary corollas, the later with showy 

 violet corollas 4-10 mm. broad, solitary or 2-3 in the axils: calyx of the 

 close-fertilized flowers with 3-4 short lobes; of the corolla-bearing flowers 

 with subulate lobes slightly longer than the tube: capsule top-shaped, open- 

 ing near the middle. Dry ground along Snake River. 



289. HKTKROCODON. 



A very delicate little annual: flowers of two sorts, the lower and 

 earlier ones with merely rudimentary corollas and self-fertilized in
