XHozamb. Bist. Tropical Transvaal ? cultivated specimens I 



This species is stated to have been riiised from seeds received from Soutli Africa, 



but I have reason to believe that its habitat is somewhere in the northern part of llie 



Transvaal. 



2. R. melanoleuca, Uooh. f.^xox. tropicalis, ^V^ E. Br. Leaves 

 glabrous ; petiole f -2J ft. long, smooth, without the soft bristles at the 

 base that are characteristic of the type; blade 8-14 in. long, 4|-14 in. 

 broad across the basal lobes, hastate or somewhat sagittate in the 

 smaller leaves, acute, green, marked with transparent white linear 

 spots ; basal lobes spreading, obtuse. Peduncle longer than the leaves,, 

 smooth. Spathe ':5-r)J in. long, lemon-yellow, with a crimson blotch at 

 the base inside ; tube funnel-shaped ; limb oblique, tapering into a 

 subulate point. Spadix shortly stipitate, not half as long as the spathe,. 

 cylindric, obtuse. Ovary subglobose, green ; style J-J lin. long ; stigma 

 small. Staminodes none, or confined to a very few of the uppermost 

 female flowers.

In the young state the leaves of this variety are elongate-ovate, acute, cordate- 

 sagittate at the base, and green without any spots, the spots develo'ping with the age 

 of the plant. 



This differs from tFe typical South African form by its larger size, and by the 

 absence of the soft bristles at the base of the petioles so characteristic of the Natal 

 plant. The stigma is not always subscssile in typical R. melanoleuca, Hook, f., as I 

 had previously described, some specimens having a distinct style about ^ lin. long. 



3. R. hastata. Hook. f. in Bot. Mag. t. 5170. Leaves with petioles 

 1-1 J ft. long, having soft bristle-like hairs on the lower part, which 

 wither and often nearly disappear in the dried state ; blade green, 

 without spots, 81-1 3 J in. long, 4-7 J in. broad across the basal lobes, 

 triangular-sagittate or hastate, acute, the part above the basal lobes 

 usually less than twice as long as broad ; basal lobes very broadly ovate 

 or rovinded, very obtuse, overlapping one another at the sinus, or 

 spreading. Peduncle about a foot long, smooth. Spathe 3-4 in. long, 

 light yellow, tinted with green outside, marked with a large purple- 

 brown blotch at the base inside ; tube funnel-shaped ; limb obliquely 

 truncate at the mouth, abruptly subulate-pointed. Spadix about half 

 as long as the spathe, cylindric, obtuse. Ovary angular-globose, light 

 green ; style very short, conical ; stigma small. Staminodes none.
