GLOBBA. 
This pretty genus is very distinct from all except the Indian 
Mantisia, in the peculiar form of the flowers, which are borne 
on a long slender panicle with short branches. The calyx is 
tubular or cup-shaped, the corolla tube usually slender and 
longer with small boat-shaped lobes reflexed when the flower 
is open, and a pair of staminodes very similar to the corolla lobes, 
The lip base is parallel to the erect stamen and its sides joined 
to it, forming a tube, the limb or free portion is narrow and 
usually bilobed. The tube contains nectar, and the entrance to 
it is a slit in front, at the foot of which is usually a brown or 
violet spot, a guiding mark for the insect visitors. The 
stamen above the lip is long and slender, and curved over 
at the top where it bears the oblong anther, which often 
has one or two pairs of processes at the sides usually flat and 
linear or triangular (the spurs), The style is lorg and slender 
and runs up along the stamen, passing between the anther cells 
in the usual way. The fruit is a small capsule as big as a pea, 
which when ripe splits widely open exposing a number of small 
brown seeds. The flowers are either yellow, or white or violet, 
and in some cases the bracts are coloured red or yellow, mak- 
ing the plants very showy. Globbas are to be found in all of
