 Odontoglossum brevifolium, Lindley, in Benth. PUmL , 

 This pretty little species is a native of the Peruvian Andes, 

 in the neighbourhood of Loxa, and was described by Lindley 

 from specimens collected by Hartweg. It is highly remark- 

 able for the shortness of the solitary leaf surmounting the 

 oval oblong flattened pseudobulb. 



Scape simple, furnished with oblong membranaceous 

 bracts ,. equal to the pedicels in length. Flowers rather large, 

 often nearly two inches in diameter, about a dozen or 

 sometimes even more borne on each scape. The sepals, or 

 outer divisions of the perianth , are rounded , wavy and nar- 



BEGONIELLA OLIVER, A NEW GENUS OF BEGONIACEAE. — 



A new genus of this family, and, apparently, a very 

 distinct one, from a country so well known comparatively 

 as New Granada is, to say the least, rather unexpected. 

 At the same time it furnishes a strong proof that many 

 interesting types of very narrowly circumscribed distribu- 

 tion may still remain undiscovered. The plant' in question 

 was found by R. B. White, Esq., in a new path through 

 the forests of the Atrato valley, at a point about thirty 

 miles due east of the town of Quibdo , on the Atrato river. 

 Its habitat is at an elevation of 500 feet above the sea 

 level , in the region of perpetual moisture , where the mean 

 temperature is 84° Fahrenheit. The plant was sent to 

 D r Hooker, and described and figured by Prof. Oliver in 

 the Transactions of the Linnaean Society, vol. XXVIII. 

 In many points of structure it agrees with Begonia but 

 differs essentially in the gamophyllous perianth of the 

 male flowers , and in having the divisions of the perianth 

 of the female flowers united above the ovary forming a 

 cup-shaped or campanulate continuation of the adherent (?) 

 floral envelop. In all previously known Begoniaceae, the 

 divisions of the perianth are free to the base in the male j 

 flowers, and in the female flowers they are not united | 

 above the ovary. The stamens in Begoniella are four in |
