Tetraneuris linearifolia obiongifolia (Greene) 



Tflraiieiiriit ohlovgifolia, Greene, Pittonia, iii, 209. (1S9S.) 

 I liave before me Palmer's No. 677, from the State of Nuevo Leon. The 

 heads are about 10 mm. l)road (exd. rays), the rays large and broad ; the 

 leaves are up to aboutoj mm. broad, and quite hairy; the achenes, pappus, 

 etc., are as in iinearifolui. I do not think this can well rank as a species. 



Tetraneuris linearifolia dodgei subsp. nov. 



About 25 cm. high, with several stems ; very hairy, the young leaves en- 

 veloped in loose tomentum ; heads (excl. rays) about 13 mm. broad ; radical 

 leaves pirrnatijicl ivilJi broad laln'al lobt's d'lver^ln^i at right angles fiom the 

 rather broad blade ; cauline leaves short and mostly quite narrow ; aristae 

 of pappus longer than in linearifolia or ahlongi folia. Monterey, Mexico, 

 " in tields, very common," May, 1891. (Chas. K. Dodge, 109 ; U. S. N. M., 

 27,471.) The heads on long upright peduncles look like thof^e of ol)lo)igifolia, 

 but the foliage is quite different. This ought perhaps to be regarded as a 

 valid species, but I expect that intermediates between it and linearifolia 

 will be found.
