EUPATORIUMS OF ECUADOR. 367 
in Engl. Bot. Jahrb. xxix. 15 (1900), its characters, very fully described 
by its author, coincide in all significant features with those of E. 
rosum. ‘The differences are almost entirely in the greater size, 
of the leaves and the more numerous florets. Neither of these matters 
seems likely to be of specific value. Klatt’s sketch of his type, a rather 
careful drawing now in the Gray Herbarium, shows the lower leaves 
more than 25 em. in length (including the winged petiole, which is 
7 em. long and 1 em. wide). The blade is about 8 cm. in breadth. It 
will be seen on comparison that the differences between these dimen- 
sions and those given for the lower leaves of E. pteropodum by Hiero- 
_ Rymus are in no way greater than are usual in individuals of the same 
species. As to the number of florets, it is true that Klatt, apparently 
without actual count, roughly estimated it at 100 in his E. nemorosum; 
ut a head from Colombian material, collected by Rusby & Pennell 
and closely matching the type-fragments in Klatt’s herbarium, had by 
careful count no less than 221 florets. The difference between 221- 
flowered in the case of E. nemorosum and 250-300-flowered as stated 
y Hieronymus for his E. pteropodum has no great significance, since 
variations of much greater latitude have often been observed in indi- 
viduals of the same species or even in heads of the same individual. 
t seems strange that Hieronymus, in describing E. pteropodum makes 
nO comparison of it with E. nemorosum so closely resembling it in all 
bed respects but states that his new plant was not nearly 
related to any previously described species. The fact, however, that 
elsewhere in the same paper lists E. nemorosum Klatt and states 
Hieron. |. ¢., as E. pteropodum.
