Of all the varieties of Dendrobium densiflorum, this is 
certainly the most profuse flowerer, and in many respects the 
most elegant, resembling D. Farmeri in the laxer raceme, and 
contrast between the colour of the lip and sepals. It was 
exhibited at the Horticultural Society by its possessor, Went- 
worth Buller, Esq., of Strete-Raleigh, Devon, in March, 1867, 
as D. thyrsiflorum, a name which I have failed to find published, 
and one not very suggestive of the differential characters of 
the plant. Professor Reichenbach, to whom I referred for 
his opinion as to its specific value, at once pronounced it a 
form of D. densiflorum, an opinion originally expressed by Mr. 
Wentworth Buller, and in which I entirely coincide; for indeed 
except in the greener, glossier pseudo-bulbs and leaves, in the 
long lax panicle, and colourless transparent sepals and petals, I 
am unable to detect any distinctive characters. It was dis- 
covered by the Rey. C. Parish, in the Moulmein forests, and 
communicated by that ardent collector to Messrs. Low and 
Co., of Upper Clapton, from whom Mr. Buller procured it. 
Descr. Stem jointed, narrowly clavate, compressed, fur- 
rowed, six to nine inches long, the joints with a membranous 
sheath. Leaves few, three to six inches long, distichous, 
broadly lanceolate, obscurely nerved, dark green, coriaceous. 
faceme lateral, from the apex of the stem below the leaves, 
recurved, pendulous, one foot long. Flowers very humerous, 
JULY Ist, 1869.
