112 Cockerell Notes on Tetraneuria Linearifolia. 



Tetraneuris linearifolia oblongifolia (Greene) 



Teiraneuris oblongifolin, Greene, Pittonia, iii, 269. (1898.) 

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

 heads are about 10 mm. broad (excl. rays), the rays large and broad ; the 

 leaves are up to about 3^ mm. broad, and quite hairy; the achenes, pappus, 

 etc., are as in linearifolia. 1 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 pinnatiji.d wilh broad lateral lobes diverging at right angles from the 

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

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

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

 27,471.) The heads on long upright peduncles look like those of oblongifolia, 

 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.
