inch long. The stems were woody throughout the three lowest 

 joints, dark red, with a strong terminal bud, and the cotyledons 

 quite withered away. There was no trace of lateral compression 

 of the petioles in the seedling stage. 



Young plants of P. marilandica, although shorter than those 

 of P. canadensis, had much larger leaves, tinged throughout with 

 red, tEe upper part of the stem being minutely hairy, with strongly 

 marked lenticels. 



P. nigra was of slower growth and smaller in all particulars ; 



the stem was minutely pilose. 



P. canescens showed a robust, wide-spreading habit ; the leaves 

 flat and broad, each pair at right angles with the next pair ; the 

 stem short and stout — all dull green. 



I have this summer raised seedlings of Poplars from widely 

 separated localities, and append a list of the species, as follows : — 

 P^canescens, from Colesborne, Gloucestershire ; P. nigra, from 

 New Ross in Ireland (from an old tree 20 ft. in girth), Bury 

 St. Edmunds, and Bourton-on-the- Water, Gloucestershire ; P. 

 canadensis and P. marilandica, from the Royal Gardens, Kew. ~

(Concluded from p. 402.) 



Ulex Gallii Planch, fvar. kumilis Planch. Plentiful on the 

 downs between Grosnez and L'Etac, Jersey. 



Cytisus scoparius Link fvar. prostratus (Bailey). Common 

 and typical on the rocks near L'Etac, Jersey. On the Sark cliffs 

 a small but not prostrate form was observed. 



Ononis reclinata L. I was rather too late in July for this 

 plant in Alderney, but a few plants still showed a flower. On the 

 dunes in Longy Bay it was dwarfed to less than an inch. 



Medicago sativa L. On West Mount, Jersey, with yellow 



flowers. Not native. — M. lupulina L. fvar. Willdenoiciana Koch. 

 Alderney. — M. minima L. West Mount, Jersey. It is very 

 curious to find that no Medicago is recorded for Sark. 



Trifolium hybrid 'urn L. Naturalized at Bel Eoyal, Jersey. 

 T. glomeratum L. Particularly luxuriant in the beds of quarries 

 near Vale, Guernsey, some specimens being over a yard across ;
