This plant has a very peculiar aspect, greatly resembling that 

 of Leucophyllum, being densely covered with long grayish tomen- 

 tum, the hairs of which are, in like manner, flexuosely branched 

 and matted together, and often stellated at some of the joints ; 

 this falls off in the older leaves, which are then marked by seve- 

 ral distinct stellated points. The leaves are 10 to 12 lines long 

 (including the very short petiole of half a line) and 5 to 6 Unes 

 broad ; they are entire, fleshy, without apparent nervures, some- 

 what rugose, and concolorous on both sides : the young leaves 

 and flowers are crowded in the nascent branchlets, the corolla 

 being small and of a violet hue : the tube of the calyx is 2 lines 

 long, terminated by five equal teeth 3 lines in length, the obtuse 

 bract being 3 lines long and 1 line broad ; the basal contracted 

 portion of the tube of the corolla is \^ line long, 1 line in diameter, 

 hence it is suddenly campanular, another line longer, and 3 lines 

 in diameter across the mouth, where it is terminated by five sub- 

 equal expanded segments, each 1^ line long and 1 line broad, 

 expanded to a diameter of 6 lines. The capsule is 2^ lines long 

 and broad ; the seeds are A line in length and barely ^ line in 

 diameter : in the structure of the capsule and seed there is much 

 analogy with that of Leucophyllum''^. 



Duboisia. 



This genus, fii-st established by Mr. Robert Brown in his 

 * Prodromus,' is very closely allied to Anthocercis, Cyphanthera 

 and Anthotroche, scarcely differing from the former except in its 

 baccate fruit. It was subsequently well figured by Endlicher in 

 his ' Iconographia,' from drawings of the celebrated artist Ferd. 

 Bauer, who accompanied Mr. Brown in his Australasian travels. 

 It was placed by INIr. Bentham in his tribe Salpiglossidece, but 



* A figure of this plant, with ample details of its structure, will be given 

 in a supplementary plate in the ' Illustrations of South Amer. Plants.'
