or near the same localities. At least two species of Den- 
drobium have been noted there by the writer, and three 
species of Peterostylis. Col. Goadby was good enough to 
send some beautiful specimens from the North of which 
D. undulatum was the most noteworthy, others having 
suffered in transit. Mr. Young was responsible for a 
curiosity in the shape of a flowering stem of D. Specio - 
sum var gracillimum which is a very attenuated form 
that was definitely recognised in 1929. Curiously enough 
many species common to the Brisbane district which are 
usually seen at our Show were not in evidence on this 
occasion. Had these appeared the list would have been 
a record. Appended is a list of those appearing in the 
different collections.

Description . — Large tree with a hard, usually very 
deeply furrowed, black bark, the furrows and cracks 
usually carrying a dark red kino or “gum.” Branches 
pendulous. Coppice shoots slender, at first angular but 
soon becoming terete. Coppice leaves linear-lanceolate 
to narrowly lanceolate, 2^-5 inches long on a slender 
petiole of i to \ inch long, and from less than \ inch to 
\ inch wide. Lateral nerves and intermediate veins 
more or less plainly_jliscernible on both faces; lateral 
veins 1 — 2 lines apart but not always clearly separable 
from the intermediate veins and reticulations; intra- 
marginal vein very close to the edge, sometimes scarcely 
separable from the slightly thickened margin of the leaf
