Macbride — North American Spermatophytes 47 
spinosa by the large flowers and less viscid pubescence. The com- 
plete synonymy of this tropical species is as follows: 
HyYDROLEA MEGAPOTAMICA Sprengl., Syst. iv. Cur. poster. 114 
(1827); Bennett, Journ. Linn. Soe. xi. 273 (1 869), not H. spinosa

HyYDROLEA ALBIFLORA (Chodat & Hassler) Brand, Pflanzen- 
reich iv. 251. 182 (1913). H. glabra Schum., var. spinosa Chodat & 
Hassler, and forma albiflora Chodat & Hassler, Bull, Herb. Boiss. 
ser. 2. iv. 64 (1904). 
This seems to be a good species. But the parenthetical authority 
is not ‘“‘ Hassler ”’ as given by Brand, I. c., but ‘‘Chodat & Hassler”’ 
as is quite evident from the original publication. Possibly it is 
hypercritical to call attention to errors of this kind — especially 
since there are few if any who do not at times make similar mis- 
takes — but in a work which is so comprehensive and imposing as 
the ‘‘ Pflanzenreich’”’ one is certainly justified in expecting a 
minimum of errors of this nature. Unfortunately these are so 
numerous that it becomes necessary to verify every reference as 
given by Brand.

The salient character of this species does not appear to have been 
brought out; certainly it was not indicated in the original publica- 
tion and the inclusion of the species by Piper and Beattie in their 
recently published ‘“ Flora of the Northwest Coast ’’ when it does 
not occur in the region their book purports to cover, would seem to 
furnish further proof that the species is not understood. Rydberg, 
l. c., segregated his species from 7’. glutinosa of the eastern United 
States on the shorter raceme, and the broader and somewhat longer 
sepals and petals. These are characters which are certainly not 
specific because they exist in varying degree in both eastern and ° 
western specimens. Collections of 7. glutinosa, especially from 
the region of the Great Lakes, often have distinctly obovate sepals 
and short racemes. Nevertheless these are referable to 7. glutinosa 
because they have the seeds of that species and the only reliable
