lipe. "March —April. Stems 6 to 12 inches long, often. de- 
cumbent. Whole plant with-somewhat the habit of Eutoca 
viscida, but riot glandular. Leaves 1 to 2 inches long. Ra- 
cemes lax; the spreading pedicels an inch long in fruit. 
Corolla ics smaller than in the foregoing species, deep blue, 
yellow at the base ; the margin of- the lobes somewhat erose ; 
the li small squamelle also as in E. strictiflora. 
— We can discern the obscure rudiments of the tubal ap- 
pendages in the corolla of Eutoca viscida. In E. hirsuta 
(Phacelia, Nutt.) No. 134 of. this - collection, they are very 
narrow but-are distinctly visible under the microscope ; as 
also in the ‘nearly allied E. ‘parviflora. Hence we should 
have no hesitation in restoring the genus Cosmanthus © e 
Nolte and-Alph. DC. to Edtóctr and Phacelia.’
