240 CAMPANULACEAE. 



358. BOLELIA. 



Low and spreading glabrous annuals, rather succulent and 

 tender; leaves sessile, narrow, entire, the upper reduced to bracts; 

 flowers axillary, sessile; calyx-tube adherent to the ovary, very 

 long and slender, 3-sided, usually twisted; corolla 2-lipped, with 

 a very short tube; filaments and anthers both united into a tube; 

 capsule long and slender, early becoming 1-celled. 



Bolelia elegans (Dougl.) Greene. Stems erect, simple or branched near 

 the base, 10-30 cm. high, glabrous throughout or very minutely puberulent; 

 leaves sessile, ovate or lanceolate, acute, 8-20 mm. long; flowers blue, in a 

 rather loose spike; bracts like the leaves but broader; calyx-tube very narrow, 

 becoming 3-4 cm. long and appearing like a pedicel; calyx-lobes narrow, 

 unequal; lower lip of the corolla sharply 3-lobed, 8-10 mm. long and broad, 

 blue with a large white and yellow center; divisions of the upper lip lanceolate. 

 Common on the margins of ponds, sometimes over extensive areas. 



359. GITHOPSIS. 



Low annual herbs; flowers all alike; calyx with a 10-ribbed 

 tube and 5 long and narrow foliaceous lobes; corolla tubular- 

 campanulate, 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. 



Githopsis specularioides Nutt. Annual,- erect, simple or branched from 

 the base, hirsute-pubescent throughout, S-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, 

 1-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, 

 Sheldon; Waitsburg, Horner. 



360. SPECULARIA. 



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 or 4 calyx-lobes ; the later with 5 calyx-lobes ; corolla 

 rotate, 5-lobed; ovary 3 or sometimes 2-celled; capsule more or 

 less elongated, opening by 2 or 3 small lateral valves which leave 

 round or oval perforations, usually over partitions. 



Specularia perfoliata (L.) A. DC. Venus' s Looking Glass. 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 or 3 

 in the axils; calyx of the close-fertilized flowers with 3 or 4 short lobes; of the 

 corolla-bearing flowers with subulate lobes slightly longer than the tube; 

 capsule top-shaped, opening near the middle. Banks and copses.
