THE ORCHIDOLOGY OF INDIA. 9 
This remarkable plant has orange-brown sepals, and in the 
shape of its parts is like .D. chrysanthum, but with ten or twelve 
flowers in a slender raceme. The petals are orange-yellow, as also 
is the lip, which has two crimson spots on each side. The flowers 
of the Khasija specimens are smaller than in those from Sikkim. 
§ VI. Actinia, Griffith, Not. ii. 320. 
In retaining this supposed genus as a section of Dendrobium, I 
must at the same time observe that the species are probably 
Pelorias of others, although, with perhaps one exception, their 
parentage cannot be traced. They are all characterized by a per- 
fect, or nearly perfect, regularity in the inner as well as outer 
series of floral envelopes, one result of which is the loss of the 
mentum, which belongs to all the other plants collected under 
the genus. In the case of D. normale, the column seems to be 
always triandrous; and in D. Pseudaclinia, there is sometimes 
an apparent attempt to gain that structure. It is, however, for 
Indian botanists to investigate this curious subject, and trace 
the monsters, if monsters they are, to their origin. Prof. H. G. 
Reichenbach has discovered that Endlicher's genus THELYCHITON, 
founded on a terrestrial Norfolk Island plant, is one of these 
Aclinias, Judging from a tracing from Ferdinand Bauer's drawing 
in the Vienna Museum, it seems possible, perhaps probable, that 
this plant (Dendrobium macropus, Н. G. Rchb.) is a Peloria of 
D. elongatum, А. Cunn. (D. brisbanense, H. G. Rehb.). I also 
much ‘suspect my genus Pastonia to be nothing more than a Pe- 
loria of Spathoglottis spicata.

Mergui, Griffith (809). 
I can have no. doubt that this is а Peloria of D. incurvum 
(infra, No. 133), which seems to have been gathered by Griffith 
inthe same place on the same day. The flowers are in pedunculate 
divaricating secund racemes, and appear to have been white, as 
Griffith describes them. 
96. D. Pseudaclinia. (Dend. Aclinia, Rchb. f. in Bonpl. Oct. 15, 1856.) 
Bootan, Hort. Kew. 
This has flowered with Consul Schiller at Hamburg as well as 
at Kew; and Prof. Rchb. informs me that it has also been received 
by the same great cultivator from Manilla. It is a slender erect 
plant with yellow flowers, springing in pairs or singly from the 
sides of the stem, І have before me a sketch by Rehb, made at
