drum or as genera nearly allied to it. Like Lelie, they are all American. 
They all have a terminal inflorescence, and many of them have, as in 
Epidendrum, the labellum united with the column at the base; but the 
pollinary arrangement is so different that some have been transferred to 
other groups, even to Vandez. The pollen-masses (4, 6, or 8) are. usually 
ovoid or globular, not at all or scarcely compressed, and distinctly separated 
in the anther by spurious dissepiments, dividing each cell into two, three, 
or four cellules or compartments; they are free, or nearly so, within the 
anther, though often after dehiscence connected by a small quantity of 
viscum, which sometimes extends into one or two elastic threads, connecting 
them also with the rostellum. The pollinary appendage so characteristic 
of Leliez is entirely wanting, or only very slight traces of it may be 
observed in a very few species.’”’ Four of the ten genera, however, were 
included by Lindley in Epidendrum, namely Lanium, Amblostoma, 
Seraphyta, and Hormidium, and the others, though somewhat anomalous, 
are nearly allied. They are Diothonea,. Stenoglossum, Hexisia, Scaphy- 
glottis, Hexadesmia and Octadesmia, and as very few of the species are in 
cultivation we will not consider them further. 
The remaining tribe Vandez forms the subject cf our next paper.

DENDROBIUM ARACHNITES. 
A preTTY little cinnabar-coloured Dendrobium exhibited by Messrs. James 
Cypher & Sons, at the Temple Show, proves to be D. arachnites, a species 
described in 1874 (Rchb. f. in Gard. Chron., 1874, ii. p. 354). It is a native 
of Burma, and was discovered by Mr. Boxall when collecting for Messrs. 
Hugh Low & Co. It is allied to D. nutans, Lindl. and D. Jerdonianum, 
Wight, but is much dwarfer in habit and has much larger flowers. The 
stems are barely 3 inches high,-and the flowers are borne in fascicles of two 
or three, and are of the most brilliant cinnabar-red, almost recalling those 
of Lelia harpophylla. The sepals and petals are linear, 14 inches long, 
and the lip elliptical-lanceolate, and similar in colour, with the addition of 
five brown lines extending from base to apex, and a few similar radiating 
veins on the side lobes. Mr. Day made a painting in June, 1886 (Orch. 
Draw., |. t. 43), from a plant in the collection of W. Lee, Esq., Downside, 
near Leatherhead, and one figure of it has been published (Gard. Chron., 
1896, ii. p. 7, fig. 2), from a plant in the collection of J. Bradshaw, Esq., 
Southgate. It is a very elegant little plant, and remarkable for its dwarf 
habit and brilliantly-coloured flowers. It is deciduous, but the leaves are 
described as linear-lanceolate, acute, and 1# to 24 inches long.
