478 GYNANDRIA MONANDRIA, Dendrobium. 
Root, from the contracted base of the bulbs issue many 
small, fleshy, ramous fibres, matted together, and adhering to 
the tree on which the plants grow. Bulbs aggregate; they 
may also be reckoned swelled stems, though I would rather 
call them bulbs; particularly as there is an articulation which 
unites the proper petiole to the apex of the bulb, and at that 
place the leaf drops off, leaving the permanent bulb naked ; 
until the new leaf comes out they are smooth, oblong, taper- 
ing equally towards each end, more or less octangular, ac- 
cording as they are plump or lean, from two to three inches 
long, and marked with two or three annular rings, the cica- 
trices of the sheath of the petioles of the former leaves, where 
some of their longitudinal fibres also remain. Leaves a sin- 
gle one, rarely two from the apex of each bulb, short-petiol- 
_ ed, oblong, entire, emarginate, veinless, and of a firm leathery 
texture, with a smooth shining surface, from four to six inches 
long, and from one to two broad, Raceme, or scape, from . 
the side of the bulb, drooping, many-flowered. Flowers 
numerous, alternate, large, beautiful, of a bright yellow. 
Bractes solitary, small, pointed, one-flowered. Corol, the 
exterior three petals sub-triangular, united round the inser- 
tion of the flower on the germ and horn of the petals ; the inner 
two oval, and larger, Lip much larger than the petals, sub- 
reniform, emarginate, of a deep yellow in the centre and paler 
round the margin. Column of fructification, or style short. 
Stigma a funnel-shaped opening in the fore-side of the co- 
_Tumn, which communicates with the belly of the germ. An- 
thers oblong, two-lobed, and covered with a two-lobed lid. 
Bs D. tripetaloides, R. 
Parasitic, Stems bulbiform, with the scape from the base 
of the bulb, many-flowered ; exterior three petals lanceolate- 
ly conic; inner two minute, Lip linguiform.
