3. T. radians Benth. Spoke-pod. Stems % to 1% feet high; blades of basal 

 leaves runcinate-pinnatifid, blades of the cauline ovate-lanceolate, auriculate-clasp- 

 ing; pods orbicular, 4 lines broad, glabrous or tomentose, the edge of the body 

 divided into radiating spoke-like nerves which disappear abruptly just within 

 the margin of the white-membranous wing; pedicels straight, spreading, abruptly 

 recurved at the very summit. 



Low hills or rolling plains, 100 to 3000 feet : infrequent, but widely distrib- 

 uted in the North Coast Ranges and Sacramento Valley and bounding foothills. 

 Apr. -May. 



Occurrence in the English foothills of the Vaca Mts. — On the gentlest slopes of the lowest 

 foothills this species has a characteristic occurrence. In wild or semi-wild land it is often abun- 

 dant. In one area of forty acres it was found in colonies 5 to 20 feet across, the plants standing 

 so thickly as to make pinkish or pale straw-colored spots on the grassy slopes. No two colonies, 

 it was noted, were exactly alike. Sometimes the differences were striking, one colony being com- 

 posed exclusively of individuals with white-winged fruits, others exclusively of individuals vnth 

 pink-vnnged fruits. Some colonies exhibited only glabrous fruits, others only pubescent fruits. 

 Other differences were slight and related to habit or leafage.

SARRACENIACEAE. Pitcher Plant Family 



Herbs. Leaves basal, with pitcher-like petioles and lid-like blades, the cavity 

 containing a liquid with properties sometimes similar to gastric juice. Flowers 

 borne on a scape. Sepals 5, persistent. Petals 5. Stamens many. Ovary superior, 

 3 to 5-celled. Fruit a loculicidal capsule. Seeds numerous, — Genera 3 and species 

 9, only in the New World (British Guiana, eastern North America, California and 

 Oregon). 



1, DARLINGTONIA Torr. 



Scapes 1-flowered, the flower pendulous. Petals with a small ovate tip (the 

 blade) and a larger elliptic or oblong lower portion (the claw). Sepals rotate. 

 Stamens 13 to 15, in a single circle. Stigmas 5, rotate on a short style which arises 

 from the umbilicate-truncate apex of the ovary. — Species 1 . (William Darlington, 

 1782-1863, Pennsylvania botanist.)
