on 
style, which affords a good index of the encroachment, comes to 
occupy a position quite at the edge of the receptacle. The slightly- 
keeled surface of the nutlet is hairy, with hairs of longer growth 
fringing the margin. When ripe, it is readily separable from its 
seat and has the shape of a meniscus. In rare instances two 
loculi develop, in which case their growth is symmetrical, the 
two shields meeting to form a ridge in the middle line. en 
the fruit is fully ripe the calycine segments, which have enclosed 
position and end their career as dry and papery wings for the 
distribution of the fruit.. The separation from the parent-plant is 
unusual. It is brought about by the drying-up and death of the 
peduncle, a process which frequently extends some distance down 
the floral axis. Vegetative growth receives renewed impulse after 
the fruit has fallen, and the leaves gain considerably in thickness 
and firmness of texture as the season advances. The roots of this 
plant are said to form a good cleansing dressing in the treatment 
of poisoned wounds. 
MBRETUM OaTeEstt Rolfe. Protogyny is pronounced, the 
the point of ripening, a bleaching sets in which reduces the colour 
to a featureless dun ; the colour revives later to the warm brown 
seen in many other species of Combretwm. The bleaching is 
usually centric in origin, passing outwards to the periphery. 
Here, as in Trichodesma physaloides, the leaves gain considerably 
in firmness with age.
