Plumbago. pentasjdria monogymia. 37 



a9 a gooseberry, about halt" the size of my F. obovata, rust-coloured, 

 smooth, pointed with the truncate base of the style, bilocular ; calyx 

 with spreading, rounded lacinia?, on a clavate pedicel about an inch 

 in length. — Cortex leathery, brown, half a line in diameter. — Pulp 

 none. — Receptacle oblong, broad, fleshy, convex and notched for the 

 reception of the seeds; the inner side smooth and concave, longitu- 

 dinally ad6xed by a narrow lamina to the side of the thin dissepiment. 

 — Seeds most numerous, ovate, angular, of a reddish brown colour, 

 shining, scabrous with copious dots. Integument simple, thickish, 

 crustaceous. — Perisperm conform to the seed, fleshy, pellucid, 

 water-coloured. — Embryo cylindrical, aqueous, occupying the -neat- 

 er part of the axis of the perisperm; cotyledons exceedingly small; 

 radicula centrifugal. 



Obs. Mr. Jack's F. racemosa is so like this species in <>ei:erul 

 appearance that I am somewhat doubtful of its bein<>- distinct. 

 The former seems not to be climbing, while this appears to be so to 

 a great extent. The leaves of that aie rounded at both ends, very 

 short-petioled ; of this they are decidedly acute at both ends and taper- 

 ing towards the base, on pretty long petioles. — The raceme in that 

 is much shorter, and more crowded -with almost sessile flowers, 

 whereas, in F. volubilis they are very long and slender, with remote 

 racemuli of pedicelled flowers. It must however be observed that; 

 the racemes in my specimens of F. racemosa are very young, oniy 

 a few flowers having opened ; it is likely, therefore, they would have 

 lengthened considerably as they advanced in age, and that, when in 

 fruit, the fascicles would have become racemuli of pedicelled calyces.
