May, 1903.] THE ORCHID REVIEW. 143 
drawings sent to Kew from the Royal Botanic Gardens, Calcutta, and 
afterwards figured (Aun. R. Bot. Gard. Calc., v; p. 6, t. 9). The plant 
was sent from the Khasia Hills, by Mr. Gallatly, and flowered at Calcutta 
in January, 1879. It now appears that Mr. Day kept an excellent drawing 
of the original type (Day Coll., xiii, t. 77), and it is interesting to note that 
a plant which has just flowered with Mr. F. W. Burbidge proves to belong 
to the species. 
Shortly after D. Williamsoni appeared, Reichenbach described another 
Dendrobium of the same group, namely D. cariniferum (Gard. Chron., 1869, 
p- 611). It came from Moulmein, and flowered with Mr. Marshall, of Enfield. 
The author remarked that there were but two others with which it could 
be compared, namely D. xanthophlebium and D. Williamsoni, both having 
a bearded lip ; the former at the base, the latter at the anterior part; but, 
he added, ‘‘ neither of the two has such a thick, long callosity ranning over 
the whole disc and middle line of the lip.” Mr. Day afterwards obtained a 
plant of it, and remarked :—‘‘ It is so like D. Williamsoni that if I were to 
draw it no one would perceive any difference.” He then pointed out 
certain slight peculiarities, and among them that the spur of D. cariniferum, 
“is rather longer and more slender,”’ finally adding ‘‘ these species, if really 
distinct, do not vary more (if so much) than the Assam and Burmah 
varieties of Dendrobes often do, for instance, formosum, aureum, chry- 
sotoxum. I believe they are the same.” 
In favour of the latter view, it may be noted that wild flowers of the 
form having a long slender spur, and labelled D. cariniferum, Rchb. fil. ; 
Mann, Upper Assam,” were found in the Herbarium of the late W. H. 
Gower, and Mr. Mann himself afterwards localised them as “ Khasia Hills, 
3000-4000 feet,” so that the geographical difference fails. Mr. Mann after- 
wards sent a drawing labelled D. cariniferum, and localised ‘‘ Nungkhlas 
[Nunklow), Khasia Hills, Assam, 4000 feet. May, 1870,”’ which shows the 
short spur of D. Williamsoni. A specimen collected by Dr. Watt, at 
Sirohifurar, Manipur, ‘‘on oaks in open places at 5000-6000 feet,” and 
labelled D. cariniferum, has also the characteristic short spur of D. 
Williamsoni. 
The flowers of both forms have a strong aromatic fragrance, strongly 
carinate sepals, and the front part of the lip strongly hirsute, while the 
colour ranges from ivory white to honey-yellow, with the markings on the 
disc deep cinnabar red. 
The late Major-Gen. Berkeley states that the species grow under much 
the same conditions of temperature, &c., as D. infundibulum. It may be 
added: that D. cariniferum var. Wattii (Bot. Mag., t. 6715) is a distinct 
species; D. Wattii, Rchb. f.
