 terminal. Inflorescence of three or more branches bearing racemose 

 cymes of very numerous flowers, the whole being 6 or more inches long

 5 acute points, a quarter of an inch long, Corolla tube one inch long 

 hairy, cylindric ba^e narrow for % inch, then dilated abruptly, hairy 

 within, limb of five spathulate lobes hairy at the base on the back, 

 one inch long, (whole flower 2 inches) and half an inch wide (dry)

This is easily distinguished from C. Rheedei by its leaves nar- 

 rowed towards each end but not cordate at the base very broadly ovate 

 or elliptic hairy on both sides, and the large cymose inflorescence of 

 many flov/ers, of much smaller size and more hairy. Derry gives the 

 name of '* Akar Gerip-gerip merah " for it, a name applied to several 

 local rubber vines. 



Closely allied to these plants is one from the Philippines, Boso-boso 

 province of Rizal, Luzon (Ahern's Collector No. II41) which has the 

 cordate leaves of C. Rheedei but hairy above, and long petioles. The 

 inflorescence resembles that of Penangensis but the calyx is very 

 deeply cut into long acute points and the f^orolla tube swollen at the 

 base and narrowed gradually upwards quite glabrous. It was dis- 

 tributed as C. macrophylla but is obviously distinct from any species 

 included under the name. I cannot find it described anywhere in the 

 Philippine Journals though a species, C. elastica Merrill, is described 

 in the Journal of Science IV. 314 which is stated to be most im- 

 portant rubber producing vine in the Philippines. The description 

 of this does not fit the Boso-boso plant, which is probably at 

 present unnamed. H. N. R. 



NOTES ON CHINESE SWINE CULTURE. 



We hav." received from M. Loudon W. Douglas a copy of an 

 important lecture delivered by him at the Farmer's Club in London 

 on the position of swine husbandry. In his letter accompanying the 

 article he writes : " The subject of swine husbandry has attracted 

 universal attention recently owing to the sudden shortage of pig- 

 products in all countries. It is a matter of very great moment to 

 agriculturists everywhere and I sincerely hope that the counsel 

 offered in my lecture may prove serviceable."
