margins of the pollen-masses in sucli a way as to be inter- 
posed between them and the Clinandriuin, or Bed of the 
Anther. These constitute true Kpidcndrece. The third * 
state of the pollen-masses depends upon the total absence 
of both caudicula and gland. Pollen of this nature may 
be considered to vary the most from the general structure 
which obtains in Orchideee, and to differ from ordinary 
pollen only in the intimate cohesion of all the granules. 
Plants with this character are c?\\ed. Malaxide€e. 
The following- is the general arrangement of Orchideae 
which has been proposed in the work above mentioned 
1. §. Neottiecp. Pollen simplex v. e gianulis lax^ cohaerentibus. 
Tribus I. Neottie.s. Anthera stigmate parallela erecta.
