pollen-masses. In Jbsepha, Wight, two species from the Indian 

 Peninsula and Ceylon, the flowers are racemose along the more 

 or less elongated branches of the panicle. In Earina, Lindl., two 

 New-Zealand species, and four more or less marked varieties of a 

 third, if not ail distinct species, from the South-Pacific islands, 

 the flowers are crowded along the short branches, sometimes 

 almost reduced to sessile clusters. 



The next group includes three "genera with small flowers 

 collected in terminal sessile heads, all three from the Indo- 

 Malayan and South-Pacific region : — Glomera, Blume, two species 

 with rather loose heads, terminating leafy stems, the flower 

 protruding beyond the bracts, and only four pollen-masses. 

 Agrostophyllum, Blume, about five species, the dense sessile heads 

 terminating the leafy stems as in Glomera, but the flowers almost 

 concealed by the imbricated bracts and the pollen-masses eight, 

 with some other differences in the structure of the flower. A. 

 megalurus^Reichh.i., from the Samoa Islands is, however, unknown 

 to me ; but from the long spiciform inflorescence and other 

 characters given (from an imperfect specimen) it can scarcely be 

 a congener. Ceratostylis, Blume, has the eight pollen-masses of 

 Agrostophyllum ; but the stems having only a single apparently 

 terminal leaf continuous with them, the little head of flowers 

 appears lateral. 



The third group comprises three genera from the Indo-Malayan 

 region with spicate or racemose flowers and eight pollen-masses, 

 the lateral sepals more or less connate at the base, with the 

 protruding base of the column forming a mentum or protuber- 

 ance, as in several of the preceding genera : — Callostylis, a single 

 Javan species, only known from Blume's 'Bijdragen' ; Crypt ochilus, 

 Lindl., two Himalayan species remarkable for the sepals connate 

 into a tubular perianth ; Trichosma, Lindl., a single Khasiya 

 species, which Lindley had at first described as a Ccelogyne, but 

 which he later followed Beichenbach in referring as a section to 

 Eria, but the habit, the strictly terminal raceme, and the 

 laterally compressed pollen-masses are those of Coelogyneae rather 

 than of Erieae. 



The fourth and typical group of Coelogyneae comprises six 

 genera with spicate racemose or solitary flowers, and no basal 

 projection to the column, of which three {Ccelogyne, Otochilus, and 

 Pholidota) are epiphytical and usually pseudobulbous, with four 

 pollen-masses, and three (Calanthe, Arundina, and Elleanthus) are
