260 THE ORCHID REVIEW. [SEPTEMBER, IQII¢ 
deservedly dedicated to Hugh Low, Esq., of Labuan, who found it om 
a mountain ‘on the north-west of Borneo, at an elevation of 3,000 feet 
above the sea level, growing on trees in exposed situations,’ whence it was. 
introduced to his father’s nursery at Clapton. It flowered in November,. 
1861.” . 
Over twenty years later a clear yellow variety appeared, which was. 
drawn by Mr. John Day on September 22nd, 1885 (Orch. Draw., xlvii, 
t. 13), when its history was given as follows: ‘‘A variety of Dendrobium. 
Lowii, with yellow instead of the bright scarlet hairs on the labellum which: 
characterise and adorn the species, and which has just flowered with~ 
Messrs. Hugh Low & Co. out of an importation of D. Lowii. This is the 
only plant which has bloomed of this variety, and they have most kindly 
sent it to me for my Scrap Book. It is interesting as a variety, but inferior 
to the species in beauty.” Shortly afterwards it was described by 
Reichenbach as D. Lowii var. pleiotrichum (Gard. Chron., 1885, ii. p. 424),- 
as follows: ‘‘ Mr. Edward Low sends mea flower of a new variety of this 
rather well-known plant. There are no red lines on the lip, and its basilar 
lacinie bear numerous short hairs.” 
When Mr. Day figured the preceding he remarked : ‘‘ Another variety 
has bloomed from this importation, more distinct than this, which the: 
Professor considers a distinct species.”” This had been drawn by Mr. Day 
on August Ist, 1885 (Day, Orch. Draw., xlv. t. 73), when its history was. 
given as follows: “©A new Dendrobium which has flowered with Messrs. 
Hugh Low & Co., and which I saw at Clapton, and borrowed from them to. 
make this drawing of. At first I thought it only a variety of D. Lowii, 
which it much resembles, the plants being just alike, but on pulling the. 
flower to pieces I saw that the labellum of this one was different from that 
of D. Lowii, so I got them.to send flowers to Prof. Reichenbach for his. 
opinion. In addition to the form of the labellum, the hairs on the ridges are’ 
very much:shorter in the new species. The only difference in the plants. 
that I could detect is that the leaves are a little longer and narrower than 
those of most of the D. Lowii at Clapton. It was received with them from. 
Borneo.” It was then described by Reichenbach (Gard. Chron., 1885, ii. p. 
198) as D. erythropogon, n. sp. (hyb. nat. ?), the author adding that the- 
flowers were smaller than in D. Lowii, and the sepals partly ochre-coloured. 
and partly whitish, the petals well undulate, and the column nearly white, 
with two scarlet spots at the base, as in D. Lowii. ‘‘ The lip offers the 
most remarkable marks of distinction. It is very. much like those of D. 
radians.” Now. D. radians is another Bornean plant which had been 
received from Messrs. Low in May, 1863, and was described as approaching 
D. longicornu in structure, and as having white flowers with some crimson 
stripes on the lip (Rchb.f. Xen. Orch., ii. p. 130, t..146, fig. 1, 2), and it is.
