The flowers are nearly white, the lateral sepals tinged with 
pink, the rest of the flower with faint green lines. The whole 
plant dries a rusty brown. On Lindley's description in Gen. 
et Sp. Orch. p. 336, with which it agrees fairly well, this has been 
taken for S. parviflorum, Sw. But Mr. N. E. Brown informs me 
that it is not Swartz's plant. Then Lindley cited Jacquin's 
figure, Hort. Schonbr. t. 179, which adds to the confusion, for our 
plant is certainly quite different. The figure shows two large 
radical suborbicular leaves lying horizontally, reflexed bracts, and 
a different ovary; the galea alone is similar. The plant is not 
uncommon; and I have drawn it twice from different localities. 
It varies chiefly in the length of the leaves, wbich are sometimes 
much reduced, aud in the width of the sepals and petals ; but the 
erect and somewhat inflated bracts and the very large limb of the 
galea are constant marks.

The leaves are a dark green; the older flowers point upwards, 
the younger downwards ; the sepals are a dull ochraceous yellow,
