DENDROBIDM. 47 



a locality 200 miles distant from the habitat of the typical D. 

 Fytchianum ; this usually flowers in April and May, the variety 

 much earlier. 



D. Gibsonii. 



Eudendrobium — Calodachyte. Stems slender, 24 — 30 inches high, 

 slightly dilated in the middle. Leaves lanceolate, acuminate, 5 — 6 

 inches long. Racemes from the upper nodes only, 5 — 7 or more 

 flowered. Flowers golden yellow with two maroon-crimson spots on the 

 disc of the lip ; sepals and petals simdar, oval-oblong, spreading ; lip 

 oblate-orbicular with convolute claw and fimbriate margin.

(1852).* 



A handsome species, somewhat resembling Dendrobium fimbrhdum 

 oculatum, from which it differs chiefly in its shorter and more slender 

 stems, in its smaller flowers, of which the petals are not ciliate, in 

 its broader lip and disc, with two spots instead of one, and in 

 the fimbriation of the lip being simple and not branched. It was 

 discovered by Gibson on the Khasia Hills, while collecting orchids 

 in India for the Duke of Devonshire, in 1836. 



D. gratiosissiinum. 



Eudendrobium — Fasciculata. Stems slender at the base, slightly 

 thickened upwards, swollen at the nodes, 12 — 18 inches long. Leaves 

 lanceolate, acute, 3 — 4 inches long, deciduous. Flowers in fascicles of 

 twos and threes from the leafless stems, 2 — 1\ inches across ; sepals 

 and petals white tipped with pale rose-purple, the former oblong lanceo- 

 late, the latter broader, ovate-lanceolate ; lip broadly ovate, acute, with 

 entire edge, white with a rose-purple blotch at the apex, and with a 

 large yellow circular blotch on the disc streaked with orange.

One of the numerous discoveries of the Rev. C. Parish in Moul- 

 in ein, and sent by him to Messrs. Low and Co., in 1865. It is 

 now rarely seen in the orchid collections of Europe ; it is probably 

 rare in its native country. Its nearest affinities are Dendrobium 

 Boxalli, D. crystallinum, and D. Devonianum, resembling the last- 

 named in habit, and the first in the size and colour of its flowers ; 

 it is best known in British collections under the name of D. Buller- 

 ianum. 



* It has still to be determined whether Dendrobium Gibsonii (Paxt.), D. fuscatum (Lindl.), 

 and D. binoculare (Rchb.), are specifically distinct, or are varieties, or even synonyms of one 

 species. In the absence of sufficiently reliable materials for comparison, we are obliged to leave 

 tnem as they are for the present.
