namia, and consequently are furnished either with a 

 silicic or short pod, or with a silique or long pod. Alys- 

 sum or mad-wort, cardamine or ladies'-smock, brassica 

 or cabbage, and so on. 



The plants of the order siliquoss, are distinguished into silicu- 

 losae aud siliquosae, from the circumstance just mentioned ; but it 

 being difficult to define the precise limits of each, Linnaeus refers 

 to the silicitlosa>, such as have a stigma without a style, and to the 

 tiliquosce such as have a style to elevate the stigma. 



ORDER XL. PERSONATE. 



41. Personate originates from persona, a mask, 

 from the flowers of its plants being furnished with an 

 irregular, gaping or grinning petal, in figure somewhat 

 resembling the snout of an animal. Anterrhinum or 

 snap-dragon, justicia, &c. 



ORDER XLI. ASPERIFOLIiE. 



42. The plants of this order are very generally 

 called rough -leaved plants, because of their usual rough 

 or harsh habit. Borago or borage, echium or viper's- 

 bugloss, pulmonaria or lung-wort, and others. 



The plants have a fibrous root. Cotyledons two ; stem branched ; 

 the branches alternate and round ; leaves alternate, simple ; neither 

 divided nor compound, for the most part nearly entire, rongh with 

 rigid scattered hairs; convolute before they expand. A common 

 flower-stalk having the flowers ranged along one side ; calyx in 

 five divisions ; corolla inferior, of one petal, regular except in 

 echium, five-cleft ; its mouth either furnished with vaulted 

 valves, or crowned with teeth, or naked stamens, five ; fruit 

 superior.
