10 ROBINSON. 


















It seems probable that the ‘ Andimarca” mentioned i is Z A 
Lucumayo Valley. The lea es in the Mathews pling are si i 
more deeply cordate and a little more bluntly toothed than the 
Cook & Gilbert plant, but in the presence of pretty close agreemen 
in all essential features these differences do not appear of much 
ficatory moment. There being, however, a slight doubt as to the 
locality of the Mathews specimen, it has seemed better to select h 
other as the type, particularly as a species — below) had 
already been dedicated to Alexander Mathew: 
E. CUTERVENSE Hieron. in Engl. Bot. Jahrb, ee 383 (1908). ’ 
species was originally found from nearCutervo and Tambillo in Ne 
ern Peru by von Jelski. It is described (Hieron. |. ¢.) as having thes 
up to 2.5 em. in thickness. This certainly must be a clerical me 
for 2.5 mm.,since surely no plant with a stem 2.5 cm. thick would be 
characterized as “suffruticosa vel fruticulosa.” The 
furthermore described as having the leaves sessile or short-peto’ 
the petioles scarcely 2 mm. long. The corolla is said to be | 
externally, the pappus whitish, and the achenes roughish on 
upper part of the angles. So far as known ni the writer the s} 
has not been subsequently reported. However, 8 have 
been collected in the vicinity of Nabén, Eouailae big

which correspond closely in nearly all described features to B.\ 
vense, having the same much-branched habit, small, roundisn 
subcordate, acute to very shortly acuminate leaves, share a 
crenate on the somewhat revolute margins. The articula : 
cence is the same, the inflorescence, and num florets ‘i 
seales (15-16) and pappus bristles (18) fairly approximate 
given by Hieronymus. The chief differences observed are as the 
the leaves in the Ecuadorian plant are never really sei an 
petioles are sometimes as much as 4 mm. long; the corols’” 
dorsally hispid; the achenes are hispidulous on the angles tht 
their length; and the pappus-bristles are distinctly roseate. 
minor differences, however, do not appear sufficient to J 
separation of the Ecuadorian plant, at least until it is possible - 
it carefully compared with the type of E. cutervense. Its : 
provisionally referred to that species. :
