An examination of the floral illustrations of X H. 
Andrewsii (Plate I, figs. 5-8; Plate II, figs. 16-22) will 
show a great variation in the flowers of this hybrid, par- I 
ticularly so in the median lobe of the lip which may be 
entire and spatulate-clavate to deeply-fringed and broad¬ 
ly cuneate or narrowly flabellate. The median lobe, as 
well as the lateral lobes, of the lip of XH.Andrewsii is 
consistently narrower than in H. psycodes or in H. psy- 
codes var. grandiflora , and wider and longer than in H. j 
lacera. The capillary fringes, when present, are for the ! 
most part longer than in either of the purple-fringed ! 
plants and more numerous than in H.lacera. The most 
constant character of the hybrid, and the one which im¬ 
mediately distinguishes it, is the shape of the petals. i 
They are inclined to be linear-oblong to linear-spatulate 
as in H. lacera. However, although they are for the most 
part entire, they may also be somewhat denticulate as in 
the Purple-fringed Orchids. 
It is highly probable that further examination of her¬ 
barium material of H. psycodes and H. psycodes var. 
grandiflora will disclose that the hybrid has a much wider 
range than is known at present, and that it is not at all 
uncommon. I am citing all the material which I have 
thus far seen. According to these records, the hybrid 
ranges from Newfoundland, Nova Scotia, New Bruns¬ 
wick, Quebec, through New England, New York, and 
New Jersey, south to North Carolina. 
The greatest number of collections of XH-Andrewsii 
has been made from New England northward. This is to 
be expected since the parent species are most abundant 
in that region and are often found growing in close prox¬ 
imity to one another in the same locality. Southward, 
H.psycodes and H.psycodes var. grandiflora are confined 
to the mountains and they become increasingly rarer as 
they approach their southern limits of distribution.
