Stigma subquadrate, concave. Anther terminal, subhemispherical, two- 
celled. Pollen-masses two, spherical, bipartite, or rather perhaps four in 
number, placed in pairs, affixed to a short, white glandular footstalk. 
From the Liverpool collection, to which it was sent from 
the Kast Indies by Dr Watuicn. Swarrz states that the 
Polystachya is an inhabitant of the Isle of France, as well as of 
Jamaica and Hispaniola in the West Indies. ; 
Mr Linp ey has given an admirable figure and descrip- 
tion of the plant in his Collectanea Botanica ; but he had not 
seen the pollen-masses in a perfect state. Still, judging from 
the habit of the individual, he thought that it would be desirable 
to divide it from Dendrobium. The nature of its pollen-mass 
is indeed quite different, and the general structure of the flower 
is also very unlike that of either D. Pierardi or D. Jimbria- 
tum; hence, not finding that this plant would agree with any 
genus of orchideous plants hithétto described, I have constituted 
a new one, derived from moruc, many, and sayus, a spike, in 
allusion to its numerous spikes borne upon the same scape} a 
circumstance so unusual in this family.
