ONCOCYCLUS 105 



52. I. Barnumae, Foster and Baker in Gard. Chron., 

 1888, ii. 182 ; Bot. Mag., t. 7050. The rhizome is 

 slender and fleshy, with the usual Oncocyclus character ; 

 the new buds become early separated by a constriction 

 from the old stock, so that the growths are not massed 

 together. The, leaves are about 6 in. long by rather 

 less than J in. broad, pointed and somewhat falcate, of 

 pale glaucous green. The stems are rather more than 

 an inch to about 6 in. long ; the spathe-valves about 

 2j in. long, rather exceeding the tube, flushed with 

 purple at the tip, but otherwise green till long after 

 flowering. The perianth-tube is as long as the ovary ; 

 falls obovate-cuneate, 2 in. long by I in. broad, with no 

 distinction between claw and blade ; the latter sharply 

 reflexed, of dark venous red-purple with darker veins ; 

 beard triangular of fluffy hairs, which are close set, 

 yellow tipped with purple, many hairs straggling away 

 from the triangular outline of the mass of the beard ; 

 standards with obovate-orbicular blade about 3 in. long 

 by 2^ in. broad, at first gradually and at last suddenly 

 narrowed to a short claw, on which are a few hairs the 

 colour of lighter red purple than the falls, but with 

 more conspicuous veins. The style branches are an inch 

 long, nearly horizontal, made reddish by red-purple 

 dots and a median streak on yellowish ground ; the 

 crests triangular, much recurved, finely serrate ; the 

 stigma with a serrate purple edge. The flowers are 

 produced in May or June, and in a warm atmosphere 

 have a delightful fragrance. It is a native of Van in 

 Armenia, and was sent to Sir Michael Foster by Mrs 

 Barnum, after whom it is named.

 fig. 1 1 6. This, I believe, is a very desirable plant. It 

 is certainly ornamental, and is remarkable in this section 

 first on account of its self-yellow flower, and secondly,
