the generic character, the original C. nebulosum, Bl. (Miq. Choix, t. 26), of Java, having 
broad petals, no arms to the column, and the mentum spur-like. A figure of this by 
Seortechini represents a pendulous plant with 2 double pollinia sessile on a broad 
semilunate gland ? (he has no specimens). Reichenbach's Bornean C. simplex can 
hardly be a congener. 
19. ERIA, Lindi. 
Epiphytes of various habit. Flowers never large or bright-coloured. 
pals free (very rarely connate), adnate to the elongate foot of the column, 
and with it forming a short or long and spur-like or saccate mentum 
(mentum 0 in Æ. leiophylla). Lip sessile on the foot of the column and 
incumbent (mobile in Æ. pulchella and barbata). Anther imperfectly 4- 
or &celled; pollinia normally 8, pyriform or broadly obovoid, attached in 
Asinti by narrow bases to a viscus.—Species upwards of 100, Tropical 
latic, 
. Perhaps the most polymorphous genus of Orchids, and very difficult of division 
mto definable groups. Though never confounded with Dendrobium, the only 
available distinctive character between these is the oblong pollinia of the latter 
genus, and more or less pyriform of Eria. In the following descriptions of the 
decies, I have omitted many characters of the column, anthers, and pollen that are 
oubtless of first-rate importance, but cannot be sufficiently well detected or 
examined in dried specimens as to afford safe sectional characters, I am unable to 
retain as sections Urostachya and Cylindrolobus. The monotypic sections Xipho- 
sum, Dilochiopsis, and Pellaianthus, are aberrant. E. pulchella, Lindl. (Callo- 
stylis, Blume), should form a section (or genus), if the lip is, as Blume says, mobile; 
Perhaps together with E. barbata, which, according to Griffith, has a tremulous lip. 
€ thickened nerves, calli, &c., of the lip in many species are very variable in 
evelopment ; and considerable allowance must be made for faulty characters due to 
and unsatisfactory condition of complicated organs that have been dried for years, 
restored by maceration or boiling.
