and having a fleshy excrescence on the disk; darker in 
colour than the sepals and petals, and marked in the centre 
and on the lateral lobes with a dark purple spot. Column 
short and minutely pubescent on the back, in the upper part. 
Stigmatic cavity angular, membranous and three-lobed, the 
central lobe subulate. Clinandrium entire. Caudicule 
two, distinct. Gland transverse. Pollen-masses compressed, 
sulcate. Anther-case one-celled, and minutely pubescent like 
the column.” 
“This species in habit, in the form of the pseudo-bulbs, 
and in the foliage, is very similar to Maz. tetragona, but the 
flowers are altogether different, and bear resemblance to those 
of Max. aureo-fulva, Hook., figured in the ‘ Floral Cabinet,’ 
ii. plate 83.” J. c. 
This plant appears to be identical with M. vitellina. With 
respect to its supposed double caudicule I must, however, 
observe that they are no more than the elastic centre which 
holds the pollen-masses of all Orchidaceous plants of the 
Vandeous division to their common caudicula, and that they 
are very different from those truly double caudicule, properly 
so called, which exist in Bifrenaria.

Leaves two, about four inches long, linear-lanceolate, and 
pointed at the apex. Scape about six inches high, smooth,

Flower smooth, internally yellow, externally purple. Bracts

Petals much smaller and shorter than the sepals, and as long 
again as the column. Labellum smooth, three-lobed, the
