(344 THE ORCHID REVIEW. [NovEMBER, 1903. 
aurea) has light.rose-purple sepals and petals, most like a reduced form of 
the pollen parent in shape, and the lip like an enlarged form of C. 
Harrisoniana ; the disc, however, shows alternate crimson and yellow 
veins, and round this is a large bright yellow area, shading off to light 
blush at the undulate margin. The others are, a fine form of C. X 
Germania (C. granulosa Schofieldiana x Hardyana), and a very richly 
coloured hybrid derived from C. Schilleriana ? andC. Triane ¢, and thus 
the reverse cross of C. X Elvina, of which it must be considered a variety. 
It bears a general resemblance to the fine natural hybrid, C. x White. 
They form a very brilliant group of autumn-flowering hybrids. 
ACIANTHUS AMPLEXICAULIS. 
ACIANTHUs is a small genus of Listera-like Orchids which is very rarely 
seen in cultivation, though one of the species, A. exsertus, R. Br., flowered 
at Kew in October, 1891, and again in the following year. Eight species 
are known, namely four from Australia, three from New Caledonia, and 
one trom New Zealand. To these must now be added an additional 
Australian species, bringing the total up to nine. It is the plant described 
in 1891 as Microstylis amplexicaulis by F. M. Bailey (Queens/. Bot. Bull., 
il, p. 18). It was found at the scrubs of Eudlo Creek, Queensland, and 
its habitat is given as “on the ground and in decayed epiphytes.” Recently 
the author has transferred it to Listera, as Listera amplexicaulis, remarking :— 
“I think when better specimens are available that the plant will prove to 
be a Listera, as in general appearance it approaches that genus” (F. M. 
Bailey, Queensl. Flora, p. 15360). An examination of the flowers of an 
authentic specimen, sent by Mr. Bailey, shows that it is a species of 
Acianthus, and as it is distinct from those previously described it must 
| bear the name of A. amplexicaulis. It is easily distinguished from the 
other Australian species by its smaller flowers and very slender segments.

PHREATIA PUSILLA.—Another Australian Orchid which was not 
allocated to its right genus is Oberonia pusilla (F. M. Bailey, in Rep. 
Exped. Bellenden-Ker, p. 62), which proves to be a species of Phreatia. 
It was found on Mount Bellenden-Ker, at about 4,000 feet altitude, 
and the author remarks that no fresh flowers were found on the plants, 
which latter were only found on one tree, on which they were very 
numerous. It is a much smaller and more slender plant than the other 
Queensland species, P. limenophylax, Rchb. f., the specimen see” 
including the raceme, being scarcely an inch high. R. A.
