Limonia [Citropsis) ugandensis n. sp., (=i 'Citvopsis sp. n.?' of 

 Mr. Dawe's Uganda list, p. 39) differs from L. Schiceinfiirthii Engler 

 in its leaves with five leaflets, from L. Preiissii Engler in its smaller 

 leaves and practically absent style, and from L. gabimeiisis Engler 

 in having broader petals and leaves not attenuated apically.

its enlarged rootstock. (Abstr. Proc. roy. Soc. N. S. Wales. 

 Aug. 1. 1906.) 



The occurrence of these enlarged rootstocks, weighing from 20 

 tot 25 Lbs., in the Australian species oi Vitis, has been recorded by 

 Baron Mueller, Thozet, Roth and others, but no chemical investi- 

 gation of their composition appears to have been made. Such an 

 investigation forms the basis of this paper. The S3'stematic side of 

 the species has received füll attention, and it is shown that the 

 morphology of the leaf is so varied that Bentham's description in 

 the "Flora Australiensis," Vol. I., p. 450, requires some additions. 

 The tuber taken for analysis weighed 2 Lbs., and was in quite a 

 fresh condition. It had a diameter of 95 mm., and a length of 190 mm. 

 It had much the appearance of a large potato, and to which, when 

 cut, it had a similar odour. The concentric rings, together with the 

 vascular bundles and the chemical results, indicate that these so-called 

 tubers are simply enlarged root Stocks, and have comparatively little 

 food value. The amount of water present was 95* 176 per cent. , of 

 reducing sugars (largely dextrose) 0*402 per cent., vegetable mucilage
