CAMPANULACEAE. 355 



upward; calyx about 2 mm. long, the lobes equaling the tube; 

 corolla white, slightly exceeding the calyx; capsule 7-12-seeded; 

 seeds favose-reticulated, ovate-oblong. 



Frequent in open pine forests in the San Gabriel and San Ber- 

 nardino Mountains. 



2. N. ramosissimus pinnatifidus (Greene) Gray. Much re- 

 sembling the last; basal leaves linear-lanceolate, 1-2-pinnatifid, the 

 cauline toothed; capsule 15-25-seeded; seeds short-oblong. 



San Gabriel Mountains, Allen. 



4. LOBELIA L. 



Herbs with alternate or basal leaves, and racemose, 

 spicate or paniculate, often leafy-bracted flowers. Calyx- 

 tube adnate to the ovary. Corolla-tube straight, oblique 

 or incurved, divided to the base on 1 side, 2-lobed; the 

 lobe on each side of the cleft erect or recurved, turned 

 away from the other 3, which are somewhat united. 

 Stamens free from the corolla-tube, monadelphous at 

 least above; 2 or all the 5 anthers with a tuft of hairs 

 at the tip, all united. Ovary 2-celled; the 2 parietal 

 placentas many-ovuled; stigma 2-lobed or 2-cleft. Cap- 

 sule loculicidally 2-valved. 



1. L. splendens Willd. Glabrous or nearly so; stems erect, 

 commonly simple, 4-8 dm. high; leaves lanceolate or almost linear, 

 glandular-denticulate, all but the lower sessile, 10 cm. long or less; 

 flowers in a rather close often elongated raceme; calyx-tube hemi- 

 spheric, 4 mm. long, the lobes linear-lanceolate, 8 mm. long; corolla 

 bright red, 2 cm. long, the tube narrow, the lobes about 8 mm. long; 

 seeds oblong, somewhat rugose-tuberculate. 



Along streams in wet places in the upper portions of the chaparral 

 belt of the San Bernardino and Cuyamaca Mountains. 



5. PALMERELLA Gray. 



Slender erect or spreading herbs, glabrous or nearly 

 so, with mostly lanceolate entire or serrate leaves, and 

 blue flowers in short terminal racemes. Calyx-tubes tur- 

 binate, the lobes slender. Corolla-tube elongated, linear 

 and straight, not at all dilated at the throat; the short 

 limb abruptly spreading; 2 lobes small, spatulate-linear 

 and recurving, the 3 larger obovate or oblong, slightly 

 united at the base. Filaments more or less adnate to 

 the corolla up to near the throat, then monadelphous 

 and free, or adnate on 1 side only; anthers oblong, the 

 3 larger naked, the 2 shorter tipped with a tuft of very 

 short bristles. Ovary and capsule as in Lobelia.
