This variety passes directly into the species through forms 

 (Hall, no. 6208, etc.) in which the inner crisped hairs of the 

 pappus-bristles are present but very sparse. All of my specimens 

 from Mt. Pinos and Fort Tejon, as well as a specimen in Dr. 

 Davidson's herbarium without locality, and also Hall & Babcock, 

 no. 5043, from the Greenhorn Range, Kern Co., Pur pus, no. 5017. 

 etc., belong to a form with entire leaves and short ligules, these 

 latter scarcely longer than broad (4 or 5 mm.) and only 8 or 10 

 in number. This form apparently a product of the arid mon- 

 tane district to the west of the Mohave Desert bears the same 

 relation to var. heterotricha that Professor Greene 's L. hispida, 37 

 from the * ' high mountains south of Tehachapi ' ' bears to typical 

 L. glandulosd. L. hispida has also been reported from near Los 

 Angeles by Professor Abrams 38 but the description in his flora 

 (under Blepharipappus hispidus Greene) is that of L. glandulosa. 

 The original description of L. hispida calls for a plant with nar- 

 row entire leaves, small heads, inconspicuous rays, and a pappus 

 with the inner hairs interlaced. 



BLEPHARIPAPPUS NUDATUS Greene, Pitt. iii. 168 (1897), is a 

 form from Lower California with entire leaves, short rays, and 

 few or no glands: approached in specimens from Del Mar, San 

 Diego Co., Brandegee. 



L. CARNOSA (Nutt.) T. & G., said by Nuttall to have been col- 

 lected on the beach at San Diego, has not been found south of 

 Monterey Co. by recent collectors. Mr. Parish 39 thinks that 

 either it has become extinct at San Diego or there was an error 

 in Nuttall's locality. It has a succulent herbage, minute white 

 rays, and 20 or more pappus-bristles, these sparsely plumose with 

 straight hairs.
