This plant has a very peculiar aspect, greatly resembling that 

 of Leucophyllujn, being densely covered with long gra}dsh 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 oflF in the older leaves, which arc 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 lines 

 broad ; they are entire, fleshy, without apparent nervurcs, 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 Hues 

 long, terminated by five equal teetb 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 1| 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 tenninated 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 ^ hne in length and barely ^ line in 

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

 analogy with that oi Leucophyllum^^ 



DjJBOlSIA. 



■own 



' Prodromus,^ is very closely allied to AnihocerciSy 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 Mr. Bentham in his tribe SaJpighssidecey but 

 subsequently I pointed out the features that separate it from the 

 Scrophulariacece^ and suggested its true position in the system 

 among the Atropacea^ in the tribe Duboisiem (Jiuj. op. i. 165). 

 Since the description of the typical plant, now forty-three years 

 ao'O, no other species has been known, and that was called 

 D. myoporoides by Mr. Brown, on account of the similarity of its 

 habit to Myoporum. This genus, indeed, serves to connect the 

 AtropacecE with the Myoporacece, as at present limited, through 

 Disoon, which has a monopetalous corolla with five equal seg-
