Distinct from Spicatum as well as from all the rest, 
Of this plant Dr. Wallich has published a figure drawn and engraved by native artists, 
e inscribed H. spicatum) by which it appears from 
(and by an 
error which he has corrected in his correspondence with m 
the short filament and trilobate lip to be a very distinct species.

labellum bis superante ; foliis lanceolatis, patentibus, subtus glabris. Nipal.”

specimens.”—I shall only remark in addition to Dr. Wallich, that the H. Speciosum is the only 
species which I have seen of this genus in which the lip is entire.

In a collection of specimens of dried plants of the order Scitaminew, sent me by Dr. Wallich, in the year 
1819, I find also a plant of one intirely different from any of those before noticed. It appears most nearly 
to resemble, particularly in its bipartite lip and hairy bracte, the H. villosum figured in this work, but differs 
in its filament which is shorter than the lip, and in the form of the anther, by which villosum is 
distinguished from all its congeners. It is also characterized by a long, linear lanceolate leaf; circumstances 
which have induced me to record it as a distinct species under the name of H. hirsutum. 
The H. coronarium, from which the genus seems to have obtained its name, is said to have been 
cultivated in this country before 1791, by Robert Udny, Esq. The numerous additions since made, have, as 
Dr. Wallich justly observes, rendered the arrangement of them difficult; but the beautiful diversities and 
permanent distinctions which an attentive examination affords, have made this labour not an unpleasing one. 
The most striking and most invariable distinction in ascertaining the species, is founded on the filament, 
which in some is shorter than, or subequal with, the lip, and in others longer. This distinction is so striking, 
that whenever the filament is longer than the lip, it is generally, if not always, double its length, so that 
it is almost impossible to mistake it. The next distinction upon which the species of this genus may be 
founded, will be derived from their general habit or mode of inflorescence, it appearing that some species 
flower irregularly in a loose spike, with involute or tubular bractes, others from an imbricated head with lax 
or closely compressed bractes, and others again in a regular spike of a singular construction, by which the 
flowers are beautifully arranged in fascicles of threes, alternating with each other on a strong, erect, common 
rachis, so as to form six distinct upright lines, which producing their flowers in succession, give a more striking 
effect and permanency to their appearance. In fact, if beauty and fragrance were the sole objects for which 
plants were cultivated, we know of none that are to be preferred to this genus.
