138 Shaw—Structure of the Flowers in 
Corolla.—The inner whorl of the perianth consists, as 
before, of one anterior and two posterior petals. The anterior 
one is hooded, the hood bears a beautiful fringed tuft, and 
the whole structure measures about 2 cm. in length. The 
two posterior ones are equal, slightly inferior in length to the 
fringed hood, and the inner margins of their distal ends are 
greatly thickened. All three petals fuse below with each 
other and with the stamens. 
Andrecium.—In this species the stamens are only six in 
number. They are nearly equal in size; the dehiscence of 
the microsporangia and the character of the spores are those 
usual to the genus. The superficial cells of the micro- 
sporangial walls exhibit stellate thickenings similar to the 
condition in P. polygama. The microspores are much larger, 
measuring at the time of pollination about 40 mm. in diameter. 
Gynecium.—Corresponding with the elaborate development 
of the flower throughout, the pistil is also highly specialized. 
The two-celled ovary is of the strict Polygala type. The 
style is very long, and just as it leaves the ovary, bends 
sharply anteriorly, and becomes nearly adherent with the 
corolla-stamen body. The petals and filaments have united 
anteriorly in such a way that the style is enclosed ina narrow 
passage. The tissues of all are more or less united, and so 
we have here a case of initial gynandry combined with a 
complete coalescence of petals and stamens. Above, the style 
expands into a free, relatively large clubshaped organ, which 
bends posteriorly in a semicircle under the hood and down- 
wards, and bears at its tip a small, glandular, stigmatic point. 
In this case also a canal traverses the style, and nearly or 
quite forms a passage from the ovarian cavity to the exterior. 
The glandular hairs noted on the ovary of the former species 
are here wanting. 
Nectary.—In line with the more showy appearance of 
P. paucifolia we find a highly developed nectary. It occupies
