and ovt-n attrmptod to get lijrlit from lliose of other institutions, E. lonicnlosutn 
has not been finnid. 
W'eddell compares E. longifolhtm with /;. )iuroIafinn Wight, and tlie narrow- 
loavrd plant of Cuming's collection does approach closely in liaUit to some 
collections of that species. Until now, tliere has been nothing here to match 
this narrow-leaved plant with any reasonable probability of identity. The want 
seems to be supplied by litir. iSci. IJIOS Foxaorlhij d- Ramos, from Guinayangaii, 
Tavahas, which has just about the appearance that an ap]>arently immature 
plant such as that of Cuming niiglit be expected to assume. Differences can 
easily l>e found; the stems are less pubescent, the longest leaf is 18 cm long 
but ^is little over 2 cm in widtli, the widest slightly exceeding 2.5 cm, and 
these longer leaves have more numerous teeth and veins, yet tlie leaves which 
have the same size as those of Cuming's collection are practically identical 
with them in these and all other characters. The alliance suggested by habit 
is no longer with E. Jinrohitum Wigbt, but through intermediates in /:. huna- 
haense and E. carinoi with E. acssile. Yet even between the three Philippine 
species, the stipules alone are sullicient for discrimination. These stipules are 
much in evidence on Jiiir. SVi. 13108; its staminate flowers are tetramerous.
