column, which is petal-like, dilated at the apex, and adherent to 
the bearded lip below. The anther is lid-like, terminal, decidu- 
ous, of two approximate cells, each containing 2 powdery-gran- 
ular pollen-masses.” This lid-like, deciduous anther is, with 
one exception, characteristic of all the members of the tribe. 
In A. bulbosa, says Gray, “ the 4 loose and soft pellets lie in an 
inverted casque-shaped case, hinged at the back, resting on a 
shelf, the lower face of which is a glutinous stigma, over the 
front edge of which the casque-shaped anther slightly projects.” 
At the bottom of the cup formed by the united sepals and 
petals there is a slight secretion, and the yellow beard on the 
lip either acts as a guide to this concealed nectar, or is an addi- 
tional attraction. “The an- 
ther is raised by the head of 
a bee when creeping out of 
the gorge ofthe flower. The 
loose pellets are caught upon 
the bee's head, to the rough 
surface of which they are 
liable to adhere lightly, and —~ 
so to be carried to the flower 
of another individual, there 
to be left upon its glut- 
inous stigma by the same 
upward movement which im- 
mediately afterward raises 
the anther lid and carries 
away its pollen to be trans- 
ferred to a third flower, and 
soon. The scape rises from 
a globular, solid bulb, and Fic, x6. Wactiais Pocowts. 
the leaf is solitary, linear, i eA. 
hidden in the sheaths of the scape, protruding from the upper- 
most after flowering.”
