In the text accompanying the figure of Z?. hulboflorum in the Icones Plaatarum Sir
Jospph Hooker remarks :—
"Additional specimens and drawings of this species received from Calcutta since its publication
in the "Flora of British India" make me doubt whether it is sufficiently distinct from 1). iicameroium.
Mr. C. B. Clarke, from examination of fresh specimens in Sikkim, describes the column as
very short with two produced spurs at the base. I have so described it in the "Flora of British
India," but on a careful examination of the column I am disposed to think that the lateral keels
of the foot of the coIumu have been taken for spurs, or may assume the form of spars in living
specimens."
lu our opinion Sir Joseph Hooker's doubt is just, and D. I
state of this.
