OCTOBER, I911.] THE ORCHID REVIEW. 291 
Another of Bentham’s minor groups is characterised by having a free 
lip without any spur, and the stems short, leafy and without pseudobulbs. 
To it are referred Ionopsis, with about ten published species, Orni- 
thocephalus, with 25, both widely distributed in Tropical America, 
Cryptarrhena, with two, Quekettia, two Guiana species, and the following 
Brazilian genera, Zygostates, with four species, Chytroglossa, with three, 
Phymatidium, with two, and Platyrhiza, with but one. They are rare in 
cultivation. The anomalous Ecuadorean genus Hoffmeisterella was also 
referred here by Bentham. It consists of a single species, and Reichenbach 
described it as having no near affinities, though he thought it mast allied to 
Trichoceros, a high Andine genus of six or seven species, which Bentham 
placed in the subtribe Notyliez, the latter an anomalous group whose dis- 
connected elements are better placed elsewhere. Trichoceros has much of 
the general character of the preceding group, the stipes of the pollinarium 
being long and slender, while the side lobes of the lip are ciliate or antenna- 
like, and the margin of the anther setose or hispid. Telipogon is an allied 
high Andine genus of over fifty species, which is unknown in cultivation, 
owing to the difficulty of getting the plants home alive. The flowers are 
handsome, and the petals and lip broad, spreading, and reticulated with 
purple on a yellow ground. 
A third group is characterised by having the lip more or less united to 
the base of the column, and to this are referred the following five genera. 
Cochlioda bears a general resemblance to Odontoglossum, under which one 
of its five species was formerly included, but it differs in the stalk of the lip 
being adnate to the column, in having two lateral stigmas—a character 
overlooked until the genus was taken in hand by the hybridist—and in its 
rose-coloured or-orange-scarlet flowers. The species are natives of Peru 
and Ecuador. - Binotia is Brazilian, and contains a single species, bearing 
a panicle of pale greenish flowers, with the stalk of the lip adnate to the 
column, but the stigma single, and in front of the column. Aspasia is a 
genus of about eight species, which was considered a section of Odonto- 
glossum by Reichenbach, but is quite distinct, the stalk of the lip, and 
sometimes the base of the petals, being adnate to the column, while the 
habit is also appreciably different. Trichopilia has about 25 species, and 
ranges from Mexico along the Andes to Peru. It has few-flowered scapes, 
and the base of the lip is more or less convolute round the column beyond 
its adnate stalk. It contains several very handsome garden plants: 
Dignanthe contains a single Mexican species, still very imperfectly known. 
Papperitzia is another Mexican monotype, with a short sac at the base of 
the lateral sepals. 
The fourth small group is characterised by having the perianth segments 
more or less united at the base into an ovoid or globose tube. There are
