of primary leaves. Twice he has found stumps of felled Sycamores 

 producing suckers with leaves in whorls of three, but whether the plants

Ribes Species and Hybrids. — Mr. E. A. Bunyard, F.L.S., exhibited 

 the following interesting forms of Ribes, for which the Committee 

 tendered him a vote of thanks : — 



Ribes alpinum. — Staminate and pistillate. Male form always much 

 more vigorous. 



Ribes x Culverwellii [nigrum X R. Grossularia) . — Fruit larger than a 

 Black Currant, purple-brown, hairy, with no Black Currant 

 flavour and very rarely produced. Seeds sterile. Raised by 

 W. Culverwell in England, and later by M. Schneider in Germany. 

 R. robustum (niveum x oxycanthoides) . — Origin unknown. Fruit 



round, black, large as a currant. 

 R. orientate. — Fruit round, red, size of Red Currant. Caucasus, 



Himalayas, and Persia. A pistillate form is known. 

 R. pinetorum. — Fruit purplish-black, hairy. 



Self-sown Dahlias. — Mr. John R. Jackson, of Lympstone, Devon- 

 shire, sent seedlings of a collerette Dahlia which had germinated in 

 the old flower-head, the latter having been slightly buried in the 

 autumn digging on an exposed site at Lympstone. Single seedlings 

 are not uncommon, but the present specimens showed several dozens.
