original E. truncatum), it would appear to be properly 

 referred to the latter. I am, however, very doubtful 

 whether the two genera can be retained ; for if so, it must 

 be on other characters than the above. In one point the 

 three Epipliylla agree, and that is the terminal position of 

 the flowers, solitary in E. truncatum and Bussellianum, 

 binate in Gaertneri, but whereas the first and last of these 

 have very numerous stamens with minute clustered anthers 

 and long slender stigmas, E. Bussellianum has few stamens 

 of unequal length, with long distant anthers and short 

 stigmas. Reviewing the species of Phyllocactus figured in 

 this Magazine, they all have flowers inserted in the cre- 

 natures of the articulations, but they display very great 

 variations in the length of the calyx tube, the obliquity of 

 the flower (but never so oblique as in E. truncatum, or two- 

 lipped), the number of stamens, size and aggregation of 

 the anthers, and in the number and length of the stigmas. 



I have retained the name of Gaertneri for this plant, as 

 that originally proposed, though only as a variety. E. 

 Makoyanum was a mere name in Makoy's Catalogue, and 

 was adopted by Pynaert under the impression that it was 

 a different species from Gaertneri, which, however, he 

 alludes to when treating of Makoyanum, but gives no 

 characters for either differing from Bussellianum. 



According to Regel, who published it in 1884, E. 

 Gaertneri was introduced by Messrs. Haage and Schmidt 

 from the province of Minas Geraes, in Brazil. According 

 to Pynaert Mr. Makoy imported it, also from Brazil, in 

 1888. The specimen here figured was obtained from 

 Messrs. de Smet, of Ghent, and flowered in a stove of the 

 Royal Gardens in April of the present year. — J. D. H.
