inch in deptli, the outer part of which is formed of the same 

 substance as the external bark of the root on which it is par- 

 asitic, and which is evidently of the same structure as that 

 of the root of Cissus augustifolia on which the R. Arnoldi 

 was found. 



It is probable that the smaller size alone would sufficiently 

 distinguish this from the last mentioned species, the buds of 

 which are stated to be one foot in diameter ; because, although 

 the respective age of these buds is not known, yet every part 

 is so perfect in the buds I dissected, even to minute and glan- 

 dular hairs, that it is not probable they would have been long 

 in this state before opening. 



There are apparently in this, five series of bracteae ; the mid- 

 dle one, at its origin, about three-eighths of an inch in thick- 

 ness, or three times the thickness of the two outer and the 

 two inner series. These bracteae are imbricated over, and com- 

 pletely envelop the perianth ; they are marked by prominent 

 veins, precisely as in R. Arnoldi ; the tube of the perianth 

 originates on a line with the central row of bracteae below the 

 two interior rows, and although in the bud at its upper part, it 

 is undivided, yet the lines of its divisions, when expanded, 

 are clearly discernable. Tlie interior of these divisions of 

 the perianth is marked by tubercles of various forms, as in the 

 other species. 



The column has a convex disc, surrounded by a raised 

 edge ; on the surface of this column are eleven processes, 

 rather more than one-eighth of an inch in height, differing 

 from each other slightly in size and form, the summits of 

 which are entire and hispid, the hairs much resembling pistil- 

 lary projections. One of these processes is in the centre, the 

 other ten arranged around it at about an equal distance be- 

 tween it and the raised edge. 



The anthers, which are of the same form, with pores and 

 cells like those of the other species described, are ten in num- 

 ber, and are also suspended from the under side of the upper 

 edge of the column, in open cavities formed in the lower part 

 or base of it ; both edges of the open part of these cavities 

 are covered with hairs resembling those on the tips of the
