Instead of the characteristic triangle, the ovary showed an oblong 

 section, and only five placental areas had been differentiated. (Fig. 184.)

Clieiranthus x Arkivrightii.—MY. Arkwright wrote regarding this 

 as follows : ' ' Though a good many seed pods seemed to be growing 

 all right for a long time, there is not a single seed to be found that 

 looks as if it could possibly germinate." (See p. cxv.)

 six members present, and W. W. Pettigrew, visitor. 



Pine seeds.- — Mr. Douglas, V.M.H., drew attention to the sale of 

 the seeds of Pinus Pinea under the name of " pignolia " in Bourne- 

 mouth and elsewhere. They are used for flavouring, &c. 



Gentiana Pneumonanthe forma alba. — Mr. Chittenden showed a 

 whit^-flowered specimen of G. Pneumonmithe, found by Admiral Carr 

 on Chobham Common. The plant was an exceedingly fine specimen of' 

 this species with white flowers ; indeed, so floriferous was it (it bore 

 eighteen almost, or quite, open flowers) that at first Mr. Chittenden 

 could not believe it to be G. Pnemnonayitlie at all. Admiral Carr 

 wrote: " The plant was found on Chobham Common, near this house, 

 about two years ago, and is growing well in my garden. Gentiana 

 Pneumonanthe is fairly common here. ... A plant has been raised 

 from seed of this wild one, also white." A white-flowered form is 

 mentioned in " De Gentiana libellus " by Froelich, published in 1796, 

 but no mention of its occurrence in Britain could be found in any 

 of the floras consulted. If Admiral Carr succeeds in raising a stock of 

 white -flowered plants, we shall have to thank him for adding a charm- 

 ing variety to those gardens where Gentians of this type succeed.
