OF THE ARILLUS 



Ova lis, concerning colour, flavour, habit 

 and structure. Fagonia and its allies form 

 the connecting link between them, which 

 Gartner and Jussieu did not overlook. 

 We have pointed out this affinity in Eng- 

 lish Botany, p. 762, and it is confirmed by 

 the curious circumstance of Jacquin's Or- 

 alis rostrata, Oxal. t. 22, having the very 

 appendages to its filaments which make a 

 peculiar part of the character of Boronia. 



It is not easy to say whether the va- 

 rious, and frequently elaborate, coat of the 

 seed among the rough-leaved plants, Bo- 

 ?*ago, Anchusa, Lithospermum, Cynoglos- 

 sum, Engl. Bot. t. 921, &c, should be 

 esteemed an Arillus or a Testa ; but the 

 latter seems most correct, each seed hav- 

 ing only a simple and very thin membra- 

 nous internal skin besides. Gsertner there- 

 fore justly uses the term Nut for the seeds 

 in question. The same may be observed 

 of Ranunculus, Myosurus, see Engl. Bot. 

 t. 435, Clematis, Anemone, &c, whose 

 external coats are no less various and ela- 

 borate ; yet such seeds are as truly naked 

 as those of the Didynamia class, figured
