to and shorter than their bracts ; bracts broadly ovate, acute, rather

 margins, otherwise glabrous, bracteoles also ovate, acute, male bracts 

 IJ lin., female 2 lin. long. Male sepals 3, yellow, orbicular, glabrous. 

 Stamens 3 ; filaments very short. Female calyx-segments 6, 2-seriate, 

 accrescent but hardly indurated, 4 lin. long, pinnately 5-6-lobulate on 

 each side, rhachis broad oblong-lanceolate, lobules triangular, shorter 

 than the diameter of the rhachis, sparingly setose outside like the rhachis

Nearest to T. glahrescens. Pax, from which it is readily distinguished by its 

 stouter stems, larger leaves, much larger male bracts and capsule, and especially by 

 the female calyx-lobes which in fruit have pinnately spi'eading in place of palmatuly 

 jiscending lobules. 



27. T. Preussii, Pax in Engl. Jahrh. xix. 102. Stem long, slender, 

 twining, without stinging hairs. Leaves distinctly to long petioled, 

 membranous, oblong-lanceolate or oblong, acuminate, narrowed from 

 the middle to the narrow-cordate or subhastate base, margin faintly 

 undulate or entire, 6J-8 in. long, 2-3"in. wide, quite glabrous on both 

 surfaces ; petiole 2-2 J in. long ; stipules slightly spreading, narrow- 

 triangular, 2 lin. long. Kacemes lateral, leaf-opposed, simple, 1-2 in. 

 long, or in pseudo-panicles terminating lateral branches, the main 

 rhachis with stipules but no leaves, 5-10 in. long, 2^-4 in. across ; 

 individual racemes 2-3J in. long, lax, with many male flowers above 

 and 1-2 female flowers near the base ; pedicels in both sexes solitary to 

 and much exceeding the bracts, 2 lin. long ; bracts narrow-lanceolate ; 

 spreading, shorter than the pedicels. Male sepals 3, ovate. Stamens ;^, 

 subsessile. Female calyx-segments 6, lanceolate, hardening but very 

 slightly accrescent in fruit, irregularly pinnatipartite, rhachis narrow, 

 with 2 or 3 unequal short lobes on each side. Ovary sparingly setose ; 

 styles 3, glabrous, united below. Capsule 3-coccous, sparingly setose, 

 J in. across ; cocci subglobose. Seeds globose, dark brown with paler 

 blotches.— I'. Winkleri, Pax in Engl. Jahrb. xHii. 82.

A very distinct species readily recognised by the length, not only of its male, but 

 of its female pedicels.
