THE SPECIES OF EPILOBIUM OCCURRING NORTH OF MEXICO, 809 
“alpinum,” FE. cian a adenocaulon, and FE. coloratum being 
among the best. They c , however, be compared for a moment 
with Cuisin’s beautiful iistes in Barbey’s Genus Epilobium, or with 
those drawn by Prof. Haussknecht; partly from a certain sketchi- 
ness, partly from being on too small a scale, but more often bivesistl 
they are evidently taken from poor specimens, carelessly dried. LH. 
hirsutum is hardly recognisable; nor do KE. holosericeum, EK. lepto- 
I do not feel qualified to dogmatise about non-Huropean species ; 
yet I find it extremely difficult 3 believe that EH. paniculatum and 
E. jucundum A. Gray can be forms of one species. The habit, size 
of flowers, and shape of petals, as aces both in Barbey’s and Prof 
Trelease’s figures, are quite as far apart as in H. hirsutum and E. 
— which none but a tyro would combine. L. hirsutum is 
o be “doubtfully established”; but in July, 1881, I found it 
rane abundantly by a stream near Rogers Rock Hotel, at the 
head of Lake George, associated with Impatiens fulva, and looking 
so artes wild that I ae it in the Hooker’s Student’s Flora 
me as if native. 
n the nomenclature adopted, two criticisms seem not uncalled 
for. ti name EF. a Lam. is substituted for the now almost 
universally accep f EL. angustifolium L., because Lamarck

stated that the latter ieee to E. Dodonas Vil. But the plant

tion that the specimen in Linn. herb. is the plant usually called 
angustifolium. ‘* EF. alpinum L.” is also used to denote the plant 
published by Haussknecht as F. lactifiorwm, on the principle of 
retaining what remains of the old aggregate, after HL. anagallidifo 
For thi
