it in his " Flore des Serres," Ser. i. vol. i. (1845) p. 4, in 

 which work it was subsequently figured by Van Houtte, 

 vol. iv. (1848) t. 386, 387, the figure being copied, without 

 acknowledgment, from that in this Magazine. It was 

 subsequently very badly figured in the Revue Horticole, 

 1853, p. 301, t. 16, with an excellent description by 

 Decaisne, who was the first (and hitherto the only) 

 botanist who recognized the true structure of the 

 staminal corona, which, like that of JV. Miersii, consists of 

 twenty filaments in clusters of four, of which the two outer 

 are alone antheriferous ; in other words, there are ten 

 antheriferous filaments approximate in pairs, with as many 

 interposed anantherous, also in pairs. Lindley had de- 

 scribed twenty antheriferous stamens, Miers correctly notes 

 ten, but does not give their arrangement, 



It remains to give the characters by which the species 

 which I have named after my late friend, the monographer 

 of the genus, may be distinguished from the very nearly 

 allied species which he has described. These are N". 

 Whitfieldii (which Miersii was supposed to be), N. 

 aispidata, and N. Mannii. From all of these K Miersii is 

 distinguished by the pale membranous more obovate leaves 

 with faint sunk nerves; further from the first (see t. 

 4387) by the much fewer larger teeth of the corolla, the 

 pale rose zone within the outer one, the white filaments of 

 the outer corona, and the longer and white colour of the 

 i >rect inner corona. Miers describes the teeth of the corolla 

 oi II hiffiddii as only forty, and the filaments of the corona 

 as scarlet, neither of which is correct. N. cuspidata is 

 described by Miers as having a purple forty-toothed 

 corolla with a pale yellow margin, yellow filaments of the 

 outer corona, and the twenty filaments of the staminal 

 corona as all antheriferous (which latter, however, I did 

 not find to be the case in the only flower which I have 

 examined). JV. Mannii, a Fernando Po species, appears to 

 me to be the nearest to N. Miersii, but besides the differ- 

 ence of foliage the flowers are much smaller ; it is 

 described by Miers as having only thirty teeth to the 

 wholly yellow corolla, and with all the filaments (twenty) 

 antheriferous; but this latter is not the case in the flower 

 1 examined, where the ten antheriferous flaments were 

 irregularly disposed. The examination of this species, and
