POLEMONIUMS. 
Tuis popular genus appears to have arrived at that 
stage of its existence when a certain amount of 
confusion seems to be inevitable, owing to the 
number of forms or varieties belonging to one or 
two of the species most generally grown in gardens 
at the present times. It is just possible that we may 
still have what can be identified as fair representa- 
tives of the original types, but these are certainly fast 
giving way to the more showy garden varieties. The 
more these forms are developed the more difficult it 
will be for the botanist to give each its relative value, 
and more especially во as the characters which at 
present distinguish certain species, are of such 
nature that EID with good cultivation, &c., 
will certainly tend in the direction of obliterating 
them altogether. Taken i in а broad sense, not more 
than three € are m Me to any extent in 
gardens; these are P. humile, P. cceruleum, and Р. 
reptans, ‘each Siriatik i in 817 іп а greater or less

P.humile, Willd.—More slénder than P. Merete and 
from a somewhat creeping rootst more or less 
viscid pubescent ; leaflets fifteen to tw wenty-one, fr fro

few in the clusters, corolla blue or lish, its 
ler rounded lob uch shorter than the short 
ovules two to four, and seeds one to two in each cell.
