bifurcated, with tlie lower branch bearing a peiodulous, flat, 

 fleshy receptacle, irregular iu outline, reddish brown in colour, 

 and varying from -i to 6 inches iu length and | to 1;^ inch in 

 breadth. The flowers, embedded on both sides of the receptacle, 

 are mostly hermaphrodite, while on its margins are ranged 

 several unisexual or sterile flowers on slender pedicels | to 1 

 inch long. The fruits, where produced, are small flask-shaped 

 berries with one to four seeds. Pte?'isanthes is closely allied to 

 Vitis, but shows in a more interesting manner the true nature of 

 the tendrils, and a special modification of the receptacle suggested 

 only in Vifis onacrostachya. — Some supplementary remarks were 

 made by Mr. C. B. Clarke, F.E.S., and Sir Hugh Low, G.C.M.G.

 white flowers, nearly 1 inch across. The plant grown in gardens 

 in this country is seldom more than 9 inches to a foot high. 

 Some comments were ofiered by Mr. Hiern and Mr. Thomas 

 Christy.
