hairs on the middle lines; sepals ligulate-acute, the lateral ones 
broad; tepals spathulate-acute, under the dorsal sepal. Lip 
adnate to the base of column, trifid in its free protracted part; 
side-lacinize angulate, middle one cuneate-obovate emarginate, 
some with a little apiculus. Spur fusiform, equalling or nearly 
equalling the stalked ovary. Column short, with a protracted 
triangular bidentate rostellar process. 
There are various settings of this vegetable gem, quite a rival 
of Malayan and Indian Anecochili. Sometimes all the leaves are 
dark green, with silver reticulations over the leaves; at other 
times the leaves are quite covered with a silver hue, and only 
the margin is dark green with some silver net-work. And then 
there are intermediate types. We felt so pleased with these 
variations, that we established a variety called holargyrus, with 
the great silver disk; and one called reticularis, for that with 
complete net-work (Rchb. fil.in Catalog. der Orchideen Sammlung 
von G. W. Schiller, Hamburg, 1857; p. 59 and plate of Orchid. 
Brasil. inedit.) Yet these are but transitory states, developing 
from reasons we do not know. Mr. Green, the able Saundersian 
gardener, has observed such transitions as well as ourselves. 
Materials :--Fourteen specimens, including wild ones, from all 
named collectors, except ‘Von Martius; sketches made since 
1846; living specimens in the garden.

A small but beautiful plant, with variously variegated leaves 
and clear white flowers. ‘The varieties of foliage are noticed by 
Prof. Reichenbach, and these are all naturally produced, being 
from plants sent from the vicinity of Rio by the late Mr. D. 
Bowman. Seeing how prone the plant is to variation in the 
markings on the leaves, there is little doubt but many interesting 
varieties might be obtained, if seedlings from any of the varieties 
could be procured. ‘The plant thrives well when grown in small 
pots, and having a mixture of light turfy loam and sand, well 
mixed with a little sphagnum, to root into. It should be placed 
in a warm shady damp part of the stove, and requires a season of 
rest after the growth is made.—W. W. S.
