the lobes of the flower; but in the living specimen it springs from the 
place where the lobes of the flower are united. In the growing plant, 
the processes of the central column were thirty-six in number, viz., 
four in the middle, ten in the second series, and twenty-two in the 
outermost row. The elevated margin of the disc of the central column 
hardly attained the height of half an inch. This species is immedi- 
ately distinguishable from the one now described as new, and inhabits a - 
different species of Cissus. 
No description exists of R. Horsfieldi, Br., which is admitted to be 
a species of Raflesia; the only notice of it is in the Linn. Trans. 
vol. xix. p. 242, “ stylis indefinite numerosis." 
Again, R. Cumingi, Br., bears on the surface of its central column 
ten to thirteen processes, one of which is central, while the rest are 
regularly ranged around it. The interior perianth is covered with 
differently-formed warts. 
Of this novel species of Raflesia (R. Rochussenii) the following 
description is given by MM. Teysman and Binnendijk :— 
“Dioica ; antheris 15-19 serie simplici disci inferum marginem 
cingentibus ; columna 15-16 sulcis descendentibus antheris oppositis ; 
disco subpatellæformi glabro stellato, vel processibus 1-2 tecto, pol- 
line rotundato hyalino. Had. Manellawangi, costam Pondok Tjatting 
dictam, in sylvis umbrosis.”

The bud, about to apid was far par thew that of R. Patma, 
and of a somewhat different hue; but the surprise of the disco- 
verers was much excited by finding that, when the flower opened, 
the dise was seen destitute of processes. In the centre alone rose a 
small needle-like point, an eighth of an inch long. The most beautiful
