Mr, Cole brook e on the Indian Species of Mtnisptrmum. 15 



that a like observation had been previously made l>\ Roiburffe 

 but unpublished ; and, in corroboration of mine, 1 now tran- 

 scribe from his manuscript the description of his Memitpertmm 

 hirsutum, and add my own of a plant denominated by him 

 M. villosum ; — a name pre-occupied, and for which 1 have there- 

 fore substituted another (M. incanum). 



Roxburgh's M. hirsutum, which he considered to he the iam 

 with M. hirsutum of Linmrus and of Willdenow, and for which 

 he cites a figure from Plukenet's Phytographia (/. .'584. f. 5.) as 

 agreeing better with it than the figure quoted by them for the 

 plant so named, has cordate leaves (broad-cordate to linear- 

 cordate) and emarginate neetarial scales, witli racemes on th»- 

 male plant, and solitary axillary flowers on the female. 



Lamarck's M. villosum, identified by him with AT. hirsutum and 

 M. myosotoides of Linmeus, and for which he cites three figures 

 from Plukenet (t. 384. /. 3, 5 and 7), is described witli leaves 

 ovate or lanceolate-ovate, and ramose sub-corymbose peduncles, 

 from one to three in an axil*. 



Roxburgh's M. villosum (my M. incanum) has broad-cordate 

 mucronate leaves, entire neetarial scales, and panicles on both 

 male and female plants. 



Willdenow's M. hirsutum, described from a figure of Plukenet's 

 (/. 384. /. 7) and Houttuyn's Compilation (iv. p. 6\6), has ovate- 

 oblong mucronate leaves, with corymbs on the male plant and 

 racemes on the female. He probably considered Lamarck's 

 M. villosum the same with M. myosotoides Linn., which is de- 

 scribed from Plukenet's third figure (t. 384. /. 3), and Burmann's 

 Indian Flora (316), as having linear-lanceolate leaves. 



Roxburgh's M. hirsutum, said by him to be common in hedges 

 in India, is the only plant which he found that he could compare
