quite smooth ; others are far larger, with a stem as thick as a goose-quill 
and a dense spike 6 inches long. The var. f is very downy, nearly a 
foot high, with the flowers separated from each other by considerable 
intervals. The size of the middle lobe of the lip is variable.

Stem rather more than a span high, with 5 acuminate sheaths. The 
spike is twisted in a single turn, and is about the size of S. estivalis, the 
flowers, however, are not half the size.

A stout plant, a foot high, with rather large flowers in a very dense 
spike. I have not seen the leaves, but they appear to be very broad.

Hab. in Mezico, prope Tetontopeque, Maio florens, Hartweg. (hab. s. sp-) 
The stems are from 1 to 14 foot high, as thick as a crow-quill, with the 
scales pressed so close to them that at first sight the scape seems to have 
no sheaths. The spike is very lax and from 4 to 6 inches long, with 
flowers resembling those of S. elata in point of size. The leaves I have 
not seen, and this circumstance, together with the statement of Llave that
