Tho minophyllous perianth, as in the case of the gall-flowers, has three lobes : a broad 



111 



opposite the side of stylar insertion, and two narrow ones-much narrower than the 



Corresponding ones in the gall-flowers-passing up one on either side of the base of the 



, : , lf the lobes curve around the edges of the convex summit of the ovary 



The style i inserted much lower down than in the case of the gall-flowers, the summit of the 



ovary always rising conspicuously above the site of insertion (Plate II, fig. 6). The style 

 is relative] • long, and over its upper half is clothed with long pointed hairs. The stigma is 

 n nnally clavate and covered by the projecting extremities of the epidermal cells. In the 



of one of the trees in Calcutta, however, the stigmata, in place of being clavate, are 

 abruptly truncate, with more or less cup-shaped extremities, as though representing a condi- 

 tion intermediate between that proper to true female and gall-flowers. In the fresh state the 

 stigma is of a bright rose-madder tint, and the style and perianth are pale pink. The ovary is 





.."• w v - o 



bro: Uy oval externally, and contains a large oval cavity. The walls are thick, especially at 



the a] x (Plate V, fig. 1). Like those of the gall-flowers, they are composed of four distinct 



strata an ext roal and internal epidermis, and two intermediate layers. The characters of the 

 component cells, and specially those of the epidermal strata, are very different from those 

 in the corresp mding tissues in the gall flowers (Plate V, figs. 1, 17). The external epidermis 

 i formed of broad cylindrical cells with a distinct cuticular covering. The hypodermis consists 

 of thin-walled cells, which, over the greater part of the surface, are arranged in two or three 



rows, but towards the apical thickening of the walls in four or five (Plate V, fig. 1). 

 Beneath this lies a single stratum of very small cells, the nuclei of which are relatively 

 larg and stain very deeply with logwood. Many of these cells contain more than one 

 nucleus. The cells of the internal epidermis are again cylindrical, and frequently 

 j>r< nt a more or less sinuous outline. Covering their internal extremities, and lining the 

 ovarian cavity, is a thin but well -differentiated cuticle, which tends readily to separate 

 in the course of preparation of specimens. The following figures show the thickness of 



the entire wall and of the individual strata over the greater part of the ovary :
