and petals similar and sub-equal, linear, acute ; lip shorter than the 

 other segments, sub-pandurate, convolute over the column at the base. 

 Column very short. 



Dendrobium arachnites, Rchb. in Gard. Chron. II. (1874), p. 354. 

 A remarkably beautiful and interesting Dendrobe of dwarf, dense 

 habit, and producing brilliant red flowers, discovered in 1873 — 74 

 by Boxall, while collecting orchids in Moulmein for Messrs. Low 

 and Co. But few plants appear to have reached England alive ; 

 the only one that we know of is in the collection of Mr. Lee, at 

 Downside, by whose kindness we are enabled to give the above 

 description.

 inches long, deciduous. Flowers with a pleasant primrose fragrance, 

 2 — 2£ inches across, on short pedicels, produced in twos and threes from
