262 ABNOTT ON SOUTH AFRICAN PLANTS. 



27. Cucurbitaceac. There are only three worth noticing : 

 the one is 31o7nordica quinqiieloba, which is a species of CepAa- 

 landra, and apparently C. quinqueloha, Schrad. ; another is 

 Bryonia grossularicefolia, E.M., which is a species of Coni- 

 andra. The third is Bryonia scahra : this belongs to Pilogyne, 

 Schrad., and probably P. Eckloni, Schrad. ; it has the stigma 

 nearly as described in that genus. But the Bryonia scabi'a, 

 variet. E.M. has the style trifid, and the stigmas precisely as 

 in B. dioica; it nevertheless seems to be Pilogyne velutina, 

 Schrad.* Now this induces a question, — is Pilogyne a good 

 genus? If it is to be retained, the character must not de- 

 pend on its being dioecious, nor on the stigmas or style, but 

 on the filaments being dilated at the apex into a cordate 

 connectivum along the margin, of which at the back are 

 placed the linear straight (i. e. not flexuose) cells : whereas 

 Bryonia would be restricted to those with the anther-cells 

 placed along the back margin of a sinuated and lobed connec- 

 tivum. In both genera the style is surrounded at the base 

 with a thick annular fleshy, usually lobed disk. To Pilo- 

 gyne in this extended sense (style entire or trifid; stigma 

 one pileate, or three flabelliform and horizontal,) would then 

 belong to the above mentioned B. Scabra Var. of Drege ; also 

 B. Maysorensis\ herb. Madr., B. HookerianaX W. and A., 

 B. umbellata^ herb. Madr., and probably some others from 



* This division of the genus, or subgenus, had been previously described 

 by Endlicher, under the name of Zehneria. 



t B. Maysorensis. Male : filaments 3, dilated at the apex, leaving along 

 each margin a linear one-celled anther ; the whole resembling a round 2- 

 celled one : there is a fleshy gland at the bottom of the perianth. Fem. : 

 style trifid at the apex with stigmas as in Bryonia, arising from a fleshy disk. 



t B. Hookeriana. Male : filaments 3, dilated at the apex, bearing a 

 linear I -celled anther on each margin at the back, the whole resembling a 

 reniforra 2-celled anther : bottom of the perianth with a gland. Fem.: 

 as in Br. dioica. 



§ B. umbellata. Male : filaments 3, dilated at tlie apex into a large 

 flat reniform body, having the linear anther-cells along the margin at the 

 back : apparently no gland in the bottom of the perianth. Fem. : style 

 arising from a 5-lobed and lacerated gland, entire : stigma large, pileiform, 

 3-lobed, sometimes 3-partite.
