22 ANNALS OF ROYAL BOTANIC GARDEN, CALCUTTA.

Rhizome thicker than a swan’s quill, woody, terete, naked 1 Stems distant on the 
rhizome, a foot high, of a few very large naked internodes 2—3 in. long by l in. diam., 
the basal narrowed, and a few short terminal ones, all dark-green, shining and deeply 
grooved, somewhat contracted at the nodes. Leaves 5—8 in. by 1—-1$ in., suberect, with 
about 7—10 longitudinal grooves on the upper surface.  Peduncles inserted at the backs of 
the leaves at their bases 3—4 in. long, as thick as a crow-quill, stiff, erect or spreading 
with several bract-like cordate brown sheaths $ in. long, and many  imbricating 
ones at its base; flowers 1 in. diam., crowded at the ends of the peduncle. Sepals 
and petals coriaceous. Lip inserted by a very short narrow claw, above which із 
a bead-like shining black callus. Column stout, incurved. Anther broadly conical. 
This fine drawing shows me that I erred when describing the Erias for the Flora of British India, 
in uniting Lindley's Е. discolor with the Malayan E. pulehelia, a much smaller plant, to which, however, 
it is very closely allied. Both are referable to Blume’s genus Callostylis (C. rigida, Blume, Bijdragen, 
` 340, Fig. 74), afterwards altered to Tylostylis (Blume Fl. Jav. Praef. vi), that of Callostylis having 
been preoccupied. This genus Tylosty/is is, though reduced to Eria by Lindley and others, I suspect a 
distinct one, remarkable for the spreading perianth, the total absence of a mentum, the lip articulate 
with the base of the column and mobile, and presenting a singular polished nob at its base. According 
to Griffith, Е. barbata, Reichb. f. has a mobile lip, but of a very different form from that of 
E. pulchella and E. discolor, and its flowers are otherwise those of a true Eria. This character of a mobile 
lip can be satisfactorily ascertained only on living specimens. If the genus Tylostylis is to be retained, 
the Malayan Æ» pulchella should take the name of T. rigida, Bl, and the species here figured of 
T. discoior. The drawing gives no indication of locality, or other information than * Orchid sent by 
Mr. Jaffray, drawn 1880, G. King.” According to the drawing the pollinia are very peculiar. I 
have not the means of verifying it. 3
