tip forms a lower lip. This is too small to form a landing. 
place for insects, but makes the flower a little more conspic- 
uous. <A proboscis about 4™" long can drain the nectar with 
ease. 
In Gray’s Manual the time of blooming is stated to be from 
July to October, while in Chapman’s Flora of the Southem 
States it is said to be in April and May. In Illinois I have 
found the plant in bloom in September. At Orlando, Florida, 
I noted it in bloom from February 18th to March 16th, andat_ 
Inverness, Citrus county, from March 15th to 23d. In Illinois! 
have seen the flowers visited by Boméus americanorum F.6 
and Calliopsts andreniformis Sm. 2. At Orlando, Florida 
I saw them visited by a bee which I failed to capture, but 
which I supposed was Anthidium notatum Latr., and by Me 
gachile brevis Say 2. 
The last mentioned insect has two boat-shaped discs with 
attached pollinia fastened to the maxillary laminae, and! 
attached to the superior (maxillary) laminz. The maxillary 
laminz are on the upper side when the proboscis is inserted 
into a flower, and are the parts which would be expected ® 
touch the disk first. But the most important consideratio® 
is that when the bee’s proboscis is folded up under the hea 
the maxillary laminz fall into such a position that the polli- 
nia retain their hold without danger of being disturbed. 
ORCHIS SPECTABILIS L.2—In my neighborhood there a 
many places favorable for the protection of this Orghis, and it 
is of rather frequent occurrence. It is found on north hill 
sides in rather shady places. The scapes grow from 1 to? 
high and bear several flowers. The labellum with its sp! 
is white. It is nearly pendant and measures from 10 to! 
long by 8 to 10™ wide. The other parts of the pariantha® 
united intoa purplish helm which effectually shelters the co 
umn and the mouth of the spar. The spur is from 1? © 
15 long, is somewhat enlarged near the tip, and the necta! 
rises 2 to 3. 
The flower is specially adapted to Bombus females. At
