Should CordyleMylis (from the clubbed shape of the column) 

 be a preoccupied name, it m ght be called Oncidiochilus 

 (from the tubercuiated apex of the !ip.) Possibly the plant 

 may be among Wallich's Nepal Orchidece. 



I have just sent home through Royle, to R. Brown, an ac- 

 count of a new genus of a peculiar type which I have called 

 Unantia, which appears to me to constitute a new group. The 

 flowers are 5-merous and hermaphrodite; the petals, sepals, 

 and stamens, in the same line of radius from the axis (op- 

 posite) ; two ovaries cohering slightly at the base, each con- 

 taining two ovules; the fruit two drupes, which are reniform 

 and oblique, with th - style carried down by the mode of 

 growth to the base, exactly as in the Menispermacece ; the seeds 

 solitary ; embryo curved, with the radicle bent towards the 

 hilum; no albumen but a thickened endopleura; and dotted 

 testa. A twiner with alternate simple leaves ; no stipule ; the 

 wood with thick medullary rays, but no distinct concentric 

 zones ; the calyx open in aestivation, the petals naked and 

 convolutely imbricated. The fruit in appearance is exactly 

 that of a Cocculus. I am utterly at a loss about its affinities. 

 You can see the plant likely in Royle's collection as Rham- 

 nus purpiii eus. I ve at present another puzzle in hand from 

 Cashmeer, which I can refer to no known natural order; 

 the characters are four unequal deciduous inferior sepals ; 

 valvate in aestivation, petals 1 — 4 or none, hypogynous ; sta-
