igor | Andrews,— Habenaria lacera x psychodes, 247 
and Orchis. So far as I know no orchid hybrid of any sort has been 
described from the region covered by Gray's Manual. An explana- 
tion could readily be found in the paucity of our species, and the 
fact that closely related sorts do not generally grow in same localities 
or bloom at same time. 
As will be seen from above descriptions the Pownal plant is almost 
exactly intermediate between the species, having with the general 
appearance of ZZ. /acera the color of H. psychodes while the internal 
organs are like neither, but a modification of both. Its habitat 
would point toward the same conclusion. The meadow mentioned 
is a favorite locality of Æ. psychodes and that species is to be found 
in all parts of it, Æ. /acera on the other hand being less numerous and 
growing only in certain parts. "The form in question was found only 
where the two species occurred together. ‘That fact is not necessary 
to our conclusion as the pollen might have been carried by the insect 
a considerable distance, but was true for all the specimens which I 
could find. i 
The form is too far removed from either species to be readily 
considered a variety of either and neither tends to such variation 
when growing alone. It can hardly pass as a species unless found 
independently somewhere. Moreover it is of slender and weakly 
growth (a frequent though not invariable characteristic of hybrids), 
hardly growing above the surrounding grass, while the species in 
same locality are extremely vigorous. To my mind the greatest 
argument of all is in the partial development of the projection at the 
mouth of the nectary which in Æ. /acera serves an important purpose 
as pointed out by Mr. Gibson in Harper’s Magazine (Vol. 94, p. 861. 
A Few Native Orchids and their Insect Sponsors), but which from 
its partial development can hardly serve any purpose in our form. 
The glands are peculiar and I examined a number before satisfying 
myself as to their shape. I found practically no variation. 
The pollen masses were also notably different as described. The 
color of pollen of hybrid was nearer that of 77. Zacera though distinct 
from both. The capsules seemed to be maturing seed as is fre- 
quently the case with orchid hybrids. "The fertility and embry- 
ological characteristics of the seeds would be an interesting subject 
for investigation. 
All in all the characteristics of the hybrid seem to show a stronger 
influence of Æ. /acera and slight variations in the type are in the
