72 REPORT ON TWO BOTANICAL COLLECTIONS FROM 



eorum 3, libera, anguste lanceolata, acuminata, carinata, glabra, ad medium ciliata; 



petala 3, euneato-obovata, prope apicem obtusum incurvum leviter connata, dorso 



pilis longis dense vestita. 

 A small stemless annual ? Leaves rosulate, very spreading, 3-4 lin. long, \-± lin. 

 broad, linear, acute, thinly cobwebby-tomentose above, becoming glabrous, glabrous 

 beneath, woolly in the axils. Peduncles 3-4 to a plant, lf-2| in. long, filiform, thinly 

 villose or nearly glabrous. Heads simple, monoecious, 2-2h lin. diam., very pale straw- 

 coloured in all parts. Involucral-bracts in 3-4 series, much shorter than the flowers, the 

 innermost f lin. long, \-§ lin. broad, oblong or ovate-oblong, acute, quite glabrous, thin, 

 semi-transparent. Flowering-bracts none. Receptacle and pedicels very woolly. Male 

 flowers much smaller than the female flowers, with rather longer pedicels, very oblique; 

 sepals 3, two of them \ lin. long, \ lin. broad, obliquely semiovate, straight along one 

 margin, very much curved along the other, acute, the third smaller, rhomboid-lanceolate, 

 acute, all bearded with short hairs at about the middle, transparent ; petals connate into 

 a very minute, stipitate, funnel-shaped cup, glabrous ; anthers white. Female flowers 

 straight, projecting much beyond the males ; sepals 3, free, 1 lin. long, \ lin. broad, narrowly 

 lanceolate, acuminate, boat-shaped, keeled, glabrous, ciliate at the middle ooly, trans- 

 parent ; petals arising a little above the sepals, scarcely \ lin. long, about \ lin. broad, 

 cuneate-obovate, obtuse and indexed at the apex, and apparently slightly connate there, 

 densely clothed with long hairs on the back ; ovary trigonous, glabrous, with a glabrous 

 style, divided at the apex into 3 simple stigmas and 3 slender clavate appendages. Capsule 

 scarcely J lin. diam. Seeds ellipsoidal, faintly ribbed, glabrous, brown.

This species much resembles Pcepalanthus simplex, Miq., but is readily distinguished 

 by the very unequal size and dissimilar form of the male and female flowers, the 

 females conspicuously projecting much beyond the males, so that the heads have a 

 somewhat echinate appearance.
