without question. Their habit is that of Eulophia; but they certainly 
have 4 pollen-masses, apparently loose in the anther. 
10. Aphyllorchis pallida, Blume Tabellen, t. 77, of which no description 
has been published, seems to be near this genus, from which, however, 
it differs in having a bordered clinandrium, a 5-lobed lip, and perhaps 
connate lateral sepals.

This plant is said by Willdenow to haye two large ovate leaves, like 
those of a Veratrum, scabrous backwards at the edge ; but all other authors 
speak of it as having only one, and I find but. one, with smooth margins in 
a beautiful specimen given me by Sir W. Hooker. Elliot describes it thus: 
* Root concatenately bulbous, leaf solitary, large, oval, lanceolate, some- 
what plaited, rigid, springing from the root and tapering at the base into 
a petiole 2 or 3 inches long. Scape 12 or 18 inches high, clothed with 
about 3 loose sheaths. Flowers in a terminal raceme, at first erect, after- 
wards pendulous. Petals linear-oblong, connivent, distinct, all nearly 
equal in size and inform. Lip unguiculate, distinct at the base, and about 
the length of the petals, dilated towards the extremity, trifid, ridged along 
the centre, the middle lobe round, with the margin undulate and crenulate. 
Column of an equal thickness and slightly curved, shorter than the lip. 
Lid of the anther membranous, caducous. Pollen masses 4, lenticular, 
waxy, attached to the summit of the column, at length deciduous." 
Dr. Asa Gray informs me that the cormi are excessively glutinous and are 
called Putty roots in the United States, where they are used by the poor as 
a cement for broken porcelain. The plant has very much the appearance of a 
Eulophia, and its round cormi, the size and form of those of Crocus luteus, 
upon a slender subterranean rhizoma, may be compared with some of the 
plants of that genus. Its pollen masses, however, appear, as far as I can 
ascertain from the dried specimens, to be destitute of gland and caudicula.
