OF THE ARILLUS 



Oardis, concerning colour, ilivour, habit 

 and structure. Fagonia and its allies form 

 the connecting link between them, which 

 Gaertner and Jussieu did not overlook. 

 We have pointed out this affinity in Eng- 

 Ihh Botany, p, 762, and it is confirmed by 

 the curious circumstance of Jacquin's Oa- 

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

 appendages to its filaments which make a 

 peculiar part of the character of Boronia. 



it is not ea^y to say whether the va- 

 rious, and frequently elaborate, coat of t^ie 

 seed among the rough-leaved plants, Bo- 

 rago, Anchusa, Liihospermiim, Cynoglos- 

 siimj: 201, Engl BoL 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 Ramincidus, Myosuriis, see Engl. Bot, 

 t. 435, Clematis, Anemone, Sec, whose 

 external coats are no less various and ela- 

 borate ; yet such seeds are as truly naked 

 ^s those of the Didynamla class, figured
