publications, and require uo comment on the present occasion. 

 To these nine I have with some doubt added Chrysocycnis, Keichb. 

 f., a single species from New Granada, which the author com- 

 pares with Triyonidium, but seems to me to be more nearly 

 allied to Cycnoches, although it be exceptional in the subtribe 

 in its peculiar habit and single-flowered scapes or peduncles. 



Subtribe 5. MAXiLLARiEiE. — The genera here included are all 

 American and epiphytical, and have the mentum of Cyrtopodiese ; 

 but the leaves are coriaceous, fleshy, or herbaceous, without pro- 

 minent parallel ribs, and the peduncles or scapes are almost 

 always single- flowered. The rhizome either bears pseudobulbs 

 with one or two leaves, or is produced into ascending or erect 

 stems with closely distichous, often equitaut leaf-sheaths, with 

 more or less developed lamina?. Of the nine genera we have 

 referred to, two or three of the smaller ones are as yet 

 rather doubtful in their affinities ; generally they connect in 

 some measure the Cyrtopodiese and the Stanhopiea? with the 

 Oncidie®. 



Stenia, Lindl., two species, one from Guiana, the other from 

 Columbia (the latter figured by Reichenbach in Saund. Ref. 

 Bot. 1. 107, as a Chondrorhyncha), is only known to me from pub- 

 lished figures and from the sketches in herb. Lindl., from which 

 it would appear to have the fleshy labellum and the pollinarium 

 of Stanhopiea?, but with the prominent mentum, foliage, and 

 inflorescence of Maxillariea?. Schlimmia, Planch., three very 

 closely allied Columbian species, w ith a peculiarly shaped perianth, 

 has all I he characters of Maxillariea>, except that the scapes have 

 several, though but few, large flowers. Clotcenia, Lindl., a single 

 Brazilian species, is only known from a single scape in herb. 

 Lindl. and horticultural reports as to its foliage. It is as yet, 

 therefore, very doubtful as to its affinities. 



Mormolyce, Feuzl, is a single Mexican species, which Lindley 

 had referred to Triyonidium ; but the perianth has none of the 

 peculiarities of that genus, and indicates a much closer affinity 

 with Maccillaria, from which, indeed, there is very little to distin- 

 guish it genevically. Scuticaria, Lindl., contains two verv closely 

 allied species with a very peculiar habit, derived chiefly from the 

 very long, terete, fleshy leaf continuous with the pseudobulb, the 

 floral characters being nearly, but not quite, those of Maxillariu. 

 The two species have been placed, the one in Maxillaria, the 

 other in Bifrenaria, on the supposition that the pollen-masses
