the others also. This little plant is the best worthy of cultivation 
of the three sp., because of its compact habit. To grow it well, 
place say fifty tubers in a shallow pot or pan, filled to within half an 
inch of the rim with black sand or sandy loam, water plentifully, 
aud keep from the. direct rays of the sun. Flowers in December 
and January. Height from 2 to 4 inches. JW. minutéflora, is 
identical with this sp. Found also in South and Western Australia. 
Corysantues, (R. Brown.) 
Dorsal sepal erect, very much ineurved and concave, hood-shaped 
or contracted, lateral sepals and petals small, linear, sometimes 
minute. Labellum erect under the galea, broadly tubular, the 
margin of the oblique orifice either shortly recurved and denticulated, 
or produced into a large concave denticulate or fringed lamina closely 
reflexed. Column short, erect. Amnther erect, 2-celled. Pollen 
masses granular, without any caudicle, dwarf terrestrial herbs, with 
small, white underground tubers nearly round, and a single oyate- 
cordate leaf, with a sheathing bract below it. Flowers solitary, 
sessile within the leaf. 
CorysantHES pruINosA. (R. Cunningham.) 
This curious little orchid is perhaps as well known as it is 
common, and as the excellent description from the ‘ Flora,” 
given above, will enable any of you to recognise it at a glance, it will 
be unnecessary for me to go any further for the purpose of descrip- 
tion. To those who wish to find this sp., I may mention that it is 
to be foundin the niddle of Spring, growing in great abundance 
all through the Tea-Tree serub, Leptospermun laevigatum, in 
the neighbourhood of Brighton, Cheltenham, and in fact, almost 
anywhere and everywhere, its shining green leaves, and small, 
brownish purple flower being easily seen peeping from amongst the 
sand, his plant has for many years been called by orchid collectors 
C. jimbriatus, but it appears that some mistake had been made, 
which has since been rectified To grow it well, it should be lifted 
shortly after flowering, when the tubers should be carefully taken up, 
placed in sandy soul, if possible, the surface from the Tea-Tree scrub, 
and grown in a shallow pot or pan with thorough drainage. Water 
should be sparingly given, until near the time of flowering. As a 
plant for cultivation, this pretty sp.is only valuable as a distinct 
plant amongst Vietorian orchids. It grows to the height of about 
from 1 to 2 inches, and like many other of the orchidex, dries black. 
Found also in New South Wales, South and Western Australia, 
and in Tasmania. Corybas prucnosus, is identical with this sp. - I 
may remark that the genus Corysanthes is also in New Zealand, 
and the Indian Archipelago.
