are yellow heavily blotched so as to be nearly covered with 

 chestnut brown ; the lip is smaller oblong panduriform, 

 apiculate, yellow at the base and chestnut brown in front,

0. cristatum, Lindley. — A pretty compact-growing and 

 free-flowering species. The pseudobulbs are conical, of a 

 light shining green, and the leaves linear-lanceolate and 

 very acute ; the many-flowered radical scape bears a raceme 

 of flowers, which are about two and a half inches across, with 

 lanceolate acuminate spreading sepals and petals, and a de- 

 flexed lip of the same form, furnished with a multipartite 

 crest, of which the anterior lobes are largest. The flowers are 

 of a honey- like yellow, with dark brown blotches which nearly 

 cover their whole surface, the petals being distinguished by 

 zigzag bars of yellow, and the base of the lip being white. 

 There are several varieties of this, some of which are very 

 deficient in colour. Prof. Reichenbach has distinguished 

 three {Gard. Chron. 1868, 1014), namely : AlgUS, bright 

 yellow with many purplish freckles and speckles, the lip 

 white with purplish markings ; Canaria, canary-yellow with 

 a single purplish blotch on each sepal and petal, the lip as 

 in the preceding ; and Dayanum, a possible hybrid, with 

 flowers of the normal colour. — Peru, Ecuador.

0. crocidipterum, Rchb. f. — A species in the way of 0. 

 TKBvium and 0. odoratum. The pseudobulbs are nearly 

 elliptical, but tapering to the apex, ancipitous, blunt at 

 the edges, and in age become wrinkled all over but never 

 furrowed ; the leaves are longicuneate ligulate acute ; the 

 flowers grow in branching spikes, and are pale yellow spotted 

 with chestnut brown, the lip having a large quadrate brown 

 spot on its anterior part, and a smaller one of similar colour 

 on each side of the calh. The flowers have a peculiar and not 

 very agreeable odour. It flowers during the autumn months.
