the narrowed base of the petals, and the sharply defined deep purple 
lines o“ the three lower petals. This last inheritance from V. primu- 
hfolia is found, however, only in the plants from the “type station,” 
Woodmere, and not in those from Rosedale; and, furthermore, the 
cucullata inheritance of acuminate leaves is lacking in the Rosedale 
plants. But this is not an uncommon experience; the several hybrid 
plants from the same parent species often inherit diversely the opposed 
parental characters. 
In the Bicknell hybrid “the pale-lilae to lavender-blue”’ of the flow- 
ers indicates a ‘blending’ of the two colors of the parent flowers; while 
in the Forbes hybrid the purple color of V. Brittoniana seems to be 
‘dominant’ over the white of V. lanceolata. In leaf-outline also V. 
lavandulacea is an evident compromise between the two parents. The 
absolute sterility of the hybrid precludes the culture of offspring, and 
the evidence that might come from fruit or seeds. 
In fact, the living plants themselves have apparently disappeared. 
Mr. Bicknell found them in two stations two or three miles apart; but 
both stations have been much disturbed, and he was unable last sum- 
mer to find further specimens. A vigorous plant was to be seen in the 
Bronx Park Garden in 1905; a root of this grew well in Middlebury 
for two years; but in both gardens the plants have since died. The 
hybrid will perhaps be rediscovered in moist meadows along the coast ; 
and if so, it may be readily multiplied by division and kept alive in- 
definitely.

THE species listed below are, except for a little material left uniden- 
tified from previous collections, the result of two trips to the mountain- 
summit, one in the late summer of 1904, the other on October first, 
1908. Both trips were by way of the Hopper, following different 
branches of the Hopper Brook up to their sources near the summit.
