principally upon one which bears the Mango. We have 
already spoken of the culture best suited to tropical para- 
sites in the 220th article of this Register. 
The following description is from the manuscript of Dr. 
Roxburgh. 
_“ Stem creeping, sending forth long thick round branch- 
“ing fleshy ash-coloured roots, which fasten firmly to the 
“trunk or branches of the tree the plant grows on. The 
“ plants are seldom more than two or three feet in length, 
“ for they decay at the base as fast as they shoot from the 
“top. Leaves sheathing, bifarious, near together, recurved, 
‘“‘ linear, keeled, forebitten, about five or six inches. long. 
“ Scapes generally axillary, solitary, naked, supporting from 
“six to twelve large beautiful flowers. Petals 5, nearly 
“ equal, expanded, oblong, waved at the edge and here 
“and there a little inflected, upper surface chequered with 
“ yellow and dusty ferruginous purple, under surface white: 
“ label shorter than the petals; spur conical, protruding 
“ towards the germen between the two lower petals; lamina 
“ (broad part) oblong, turgid, apex 3-lobed, sides inflected, 
“so as to be convex above and deeply concave underneath, 
“colour blueish purple towards the apex: upper lip or 
“* portion which forms the attachment of the base and horn 
** to the base of the column of fructification, with two late- 
“ral obliquely broad lanceolate Jobes having acute points 
“ineurved towards the summit of the column. Column of 
“ fructification thick, short, obtuse, open at the inner mar- 
gin next the summit; this mouth or opening tapers down 
“ through the column into a point, which ends in the cavity 
“of the germen; anther lidded, suborbicular, with two 
“ lidded cells for the two globular pollen masses which rise, 
“‘ when the lid is removed gently, with a jerk on their broad 
* cordate filament, which is inserted on the anterior part of 
“ the top of the column, by a large funnelform base. If re- 
“ moved with less care, and before the pollen masses are 
“ ripe, these remain in their cells, and the funnelshaped base 
“ of the filament rises erect. Stigma or channel for con- 
_ “ veying the subtle essence of the pollen to the germen, a 
“ clammy opening in the fore part of the column near its 
“top. Pericarp clavate, with six sharp ridges running 
* the whole length.” Roxb.
