ROXBURGH'S HORTUS BENGALENSIS.

India, there is double reason for taking it up. It is based 

 primarily on "Marrubium Amboinicum album Rumph. Amb. 1. 

 8. c. 75. tab. 72." 24 It has especial importance as the type of 

 the genus Coleus Lour. 



Ruellia cernua Roxb. is maintained 25 for a species of very 

 local distribution in India, which can hardly possibly be typified 

 by a description founded on a plant of Amboina. 



Calla oblongifolia is the basis for Aglaonema oblongifolium 

 Schott, but following the synonymy cited, would not have been 

 the oldest name, but for the corrected date of publication. 



Ficus infectoria Roxb. is not the species of that name in recent 

 works, 26 but being based on Hort. Malab. 3: pi. 6U, is Ficus 

 Tjakela Burm. 



Gnetum scandens Roxb. is maintained in the Flora of British 

 India, but its oldest name is G. edule (Willd.) BL, based on the 

 same plate of Rheede. 



Morus paniculata Roxb. appears to be the oldest name for 

 Pipturus velutinus (Decne.) Wedd. 



The treatment of the names Sagus spinosus and S. inermis, as 

 compared with that of the plates on which they are based, is 

 different in the Flora of British India 27 and in the Hortus 

 Bengalensis. 



Pandanus furcatus Roxb. is maintained, 28 but Rheede's plate 

 on which it was based is cited under P. fascicularis Lam. 



Batis spinosa Roxb. is treated 29 as the original publication of 

 the species known as Plecospermum spinosum Trecul, but with 

 the exclusion of the synonym of Rumphius, which is its sole 

 basis. 



Lycopodium aristatum is doubtfully placed by Baker 30 under 

 Selaginella exigua Spring. 



Piper arborescens Roxb. ex Wall. Cat. is identified 31 as 

 Thottea dependens KL, but there can be no doubt that the true 

 Piper arborescens, typified by Herb. Amb. 5: pi. 28. f. 1, is 

 a genuine Piper. 



84 The plate number is wrong, and a better citation would be Herb. Amb. 

 6: 294. pi. 102, f. 2.
