﻿92 PLANTS PRATTENIAN^] CALIFORNIA. 



There is only a faint indication of the bearded ring so manifest on the tube of the 

 disk corollas of L. Douglassii, nor do the achenia show a trace of the capitate hairs 

 of that species. The appendages of the style, moreover, are very obtuse, and desti- 

 tute of the abrupt and sharp tip. Still it is an undoubted congener of L. Douglassii. 

 (Prof. Gray in litt.)" 



I have several fine specimens of this plant, collected by Mr. Pratten at Nevada, 

 and by Dr. Heermann at Calaveras. The scapes are simple, sparingly leafy at the 

 base, from 5 — 7" high, sometimes solitary, sometimes 2-3-4 from the same root. 

 Leaves rather succulent, opposite or alternate, the lowest radical simple, linear spathu- 

 late ; the others 3 — 5-parted with linear spatulate segments. Flowers in my speci- 

 mens as large as in L. Douglassii, if not larger ; rays 3-toothed, of a brilliant yellow 

 color. Evidently growing in a muddy soil.

" C. Fremontii, Torr. is founded on a plant collected by Col. Fremont in his first 

 expedition to California, in 1846. It belongs to the section Osmaclenia, Torr. and 

 Gr. Fl. Am. vol. ii. p. 402, but the cup-shaped stipitate gland on the floral and fasci. 

 culate cauline leaves, and the teeth of the disk corolla, are short and ovate. It differs 

 in these respects from G. tenella, and thus connects the section Osmadenia with 

 Eucalycadenia. It is stouter and more hairy than C. tenella, but seems to grow erect, 

 and with but little tendency to spreading." (Torr. in litt.)
