 2-3 in. high, with a few pairs of small narrow leaves and rather simple and i- 

 flowered, or divided into 2 or 3 branches each with a small yellow flower. Calyx 

 campanulate, with 4 broad, short lobes. Corolla 4-cleft. Capsule globular, i- 

 celled. 



Damp, grassy, or sandy places, rather rare. May-July. 



C. pUsillaGriseb. (Bxacum pusillum DC.). A still smaller slender annual, 

 much more branched and differing chiefly by its yellowish-white flowers, with

 through them. Flowers bright yellow, in rather loose terminal cymes. Corolla 

 nearly rotate. 



Woods and grassy hills. May-September. 



C. serotina K. An erect glaucous annual with ovate leaves rounded at 

 the base, and yellow flowers. Calyx lobes obscurely 3-nerved, linear-lanceolate,

QENTIANA L. 



The only gentians found in the Var are Q. lutea L., Q. cruciata L., and 

 Q. verna L. ; but the two last are extremely rare, and probably no species

 Alpes-Marit. Perhaps Q. cruciata and Q. excisa Presl. descend lowest (to 

 about 800 m.) in the whole region.
