354 CAMPANULACEAE. 



1, L. biflora (R. & P.) Britton. Glabrous or nearly so; stem 

 simple or branched, roughish on the angles, 15-30 cm, high; leaves 

 ovate, oblong or the upper lanceolate, sessile, acute or obtuse at 

 the apex, crenate with few teeth or entire, 8-20 mm. long; the calyx- 

 lobes of the earlier flowers ovate to lanceolate, of the later lanceolate- 

 subulate; capsule oblong-cylindric, 6-10 mm. long, opening by 

 valves close under the calyx-teeth. {Specularia biflora Gray.) 



Occasional on grassy slopes. 



2. GITHOPSIS Nutt. 



Slender annuals with rather small linear-oblong coarse- 

 ly toothed sessile leaves. Flowers simply terminating 

 the branches or becoming lateral, erect, all alike. Calyx- 

 tube club-shaped, strongly 10-ribbed, adnate to the sum- 

 mit of the ovary, its limb of 5 long and linear foliaceous 

 lobes. Corolla tubular-campanulate, 5-lobed. Fila- 

 ments short, dilated at the base; anthers long, linear. 

 Ovary 3-celled; stigma 3-lobed. Capsule club-shaped, 

 coriaceous, crowned with the rigid calyx-lobes of its own 

 length, strongly striate-ribbed, many-seeded, opening 

 when the somewhat persistent base of the style falls away 

 by a round hole in its place. Seeds fusiform-oblong. 



1. G. specularioides Nutt. Stems simple or with 1-2 proliferous 

 branches, 5-20 cm. high, hirsute or glabrate; leaves linear-oblong, 

 6-10 mm. long, the lower obovate, 2-4 mm. long, all sharply few- 

 toothed; calyx-lobes 6-18 mm, long, shorter than or much exceeding 

 the corolla; corolla purplish, its lobes shorter than the tube; capsule 

 turgid, tapering into a very short peduncle.

3. NEMACLADUS Nutt. 



Low and diffusely branched annuals, with numerous 

 capillary branches, cauline leaves minute, sessile, sub- 

 tending the dichotomous branches. Flowers minute on 

 rather long capillary pedicels. Calyx partty or wholly 

 free. Corolla bilabiate, the upper lip 2-lobed or 2-parted, 

 the lower 3-lobed or 3-parted. Filaments monadelphous 

 to near the base; anthers oval, glabrous. Style incurved 

 at the tip; stigmas capitate, 2-lobed. Capsule 2-celled, 

 2-valved from the tip, 7-40-seeded. 



1. N. ramosissimus montanus (Greene) Gray, Glabrous 

 throughout or sparsely puberulent below and occasionally with 

 some villous hairs at the base of the pedicels; stems diffusely and 

 dichotomously branched, very slender, 1-2 dm, high; basal leaves 

 obovate, denticulate, 1 cm. long; pedicels 1-1.5 cm. long, curved
