576 DP.. M. T. MASTERs's SUPPLEMENTARY 



ovoid subtriquetrous flower. The outer perianth-segments are 

 brownish, cartilaginous, oblong obtuse, the lateral ones condupli- 

 cate, with a narrow glabrous keel ; the three inner perianth- 

 segments are one third shorter, all equal in size and form and 

 membranous in texture. The anthers are oblong and destitute 

 of mucro. 



If this be really correctly referred, it is remarkable that it has 

 not been met with before, for, while specimens of the female 

 plant are to be found in most herbaria, this is, so far as I know, 

 the only male plant in collections.

 (Plant, masc. hactenus incognita? descriptio.) 



Among Rehmann's specimens in the herbarium of the British 

 Museum is one (no. 1803) that is so obviously the male plant of 

 Restio bigeminus (hitherto undescribed), that 1 have no hesitation 

 in describing it as such, as follows : — 



Culmi vagina?que ut in feminea. Spicula? mascula? pauea? in 

 cymam patulam seu vix pendentem disposita?, singula? pedicel- 

 late 12-14 mm. longa? lineari-oblonga? acuta? pluri flora?. Bracteae 

 oblongae acuta? subcoriacea? fusco-purpurea? nitidiuscula? pluri- 

 nerviea? quam flores brevius stipulati oblongo-acuti coropressi 

 dimidio longiores. Perianthii segmenta exteriora cartilaginea 

 oblonga acutata, lateralia conduplicata, segmenta interiora con- 

 formia minora tenuiora ; anthera? lineares apiculatse.

The bracts of both male and female plants have a peculiar 

 lustrous metallic appearance.
