144 WRIGHT : THE GENUS DI08PYR0S 
Calyx 2-3-lobed at apex, at first closed and may remain so, 
though ripe pollen grains formed within ; segments thick, 
greenish-yellow, ventral surface pubescent. 
Corolla yellow, urceolate, throat very narrow (c/. D. 
Embryopteris), and appears to be frequently closed ; base 6 
mm. diameter, apex 3 mm. diameter ; segments 4, middle 
line pubescent on ventral surface, 08-1*5 mm. thick. 
Stamens numerous and irregular, 18-24-33, yellowish- 
white, unequal length, hypogynous group or terminating 
receptacle; anthers 2 mm. long, not strongly apiculate, 
sometimes sessile, glabrous ; filaments 2 mm. in length, 
white, glabrous, sometimes absent ; pollen isodiametric, 
even outline, 2 mm. diameter, show one thin part in wall. 
Pistil rudimentary disc or absent. 
Female flowers solitary or cymose, occurring only on the 
lower part of young shoots in the axil of a bract or foliage 
leaf ; bracts green to brown, caducous, small ; pedicel green, 
covered with short adpressed hairs, 6-10 mm. long, 2 mm. 
diameter, widening to wards flower. 
A ringed scar is noticeable on the pedicel of each flower 
when solitary, which is probably the area of attachment of 
at least two bracts at an early stage, thus suggesting a 
cymose inflorescence with abortive lateral flowers. Such 
an inflorescence is shown in pi. X., fig. 9. 
Flowers globose-apiculate in bud, with broad base, green^ 
hairy, 5 mm. long ; remain closed for a long time as in the 
male. 
Calyx 4-lobed, segments deeply divided, tapering acute 
apex, green, both surfaces pubescent, dorsal surface silvery 
in appearance. 
Corolla yellowish-white, tubular, urceolate ; segments 4, 
short, and triangular-shaped, with acute apices. 
Staminodes 12-16, usually as an epipetalous ring, short, 
white ; anthers broad. 
Pistil green, tetrahedral in bud and densely pubescent ; 
style 0, stigmas 3-4, short ; ovary 4-5-6-celled.
