distinguislicd from each other ; the points noticed by 
Swartz appearing to be altogether inapplicable. To this 
species, which we have compared with authentic speci- 
mens from himself in the Banksian Herbarium, he attri- 
butes triangular flowers, while, in fact, they possess that 
character in a much less degree than S. micrantha, to 
which he assigns hexangular flowers. The latter species, 
elegantly figured by Dr. Hooker in his Exotic Flora, differs 
from the subject of this article in having a rigid obtuse 
leaf, and a compact raceme of nodding flowers, which, 
when closed, present a distinctly triangular appearance. 
In all which characters it is opposed to S. ophioglossoides. 
The leaves of the latter are more membranous, and are 
almost always recurved at the end, where they are some- 
times toothed ; the flowers are larger and less compactly 
arranged in the spike ; there is also a difference in the form 
of the inner floral segments and labellum. S. micrantha 
would therefore be more satisfactorily characterised thus : 
S. micrantha (Swz.), foliis oblon«)-lanceolatis obtusis coriaceis, floribus 
nutantibus secundis trigonis, sepalis interioribus apiculatis labelli con- 
formibus. 
Of S. ophiogloi^i^Oides we possess native specimens from 
St. Vincents, communicated to ns by ovir friend Dr. Hooker ; 
they in no essential point difter from the plants in our 
gardens. ' 
Leaves solitary, oblong, smooth, flat, nerveless, nearly 
entire at the end, narrowed into a channelled fleshy stalk. 
Raceme terminal, filiform, many-fiowered, longer than the 
leaf, dotted at intervals with small truncate acuminate 
vaginae. Flowers very minute, resupinate, somewhat on 
one side, roundish, with 6 obsolete angles. Perianth, with 
the Outer sepals, ovate, obtuse, coriaceous, connate, and 
somewhat fornicate at the base, equal; inner, dwarf, fleshy, 
and truncated. Zip fleshy, parallel with the column, nearly 
of the same form as the inner sepals, with a depressed 
cordate lamina. Column very short, half-round, the length 
of the inner sepals. Anther terminal, opercular, 1 -celled, 
deciduouig. Follen-masses 2, loose, with no caudicula.
