 specimens! Female gland 1, semicircular, and recognisable in fruit. Stamens 

 •15" long, 5-10. often 7, pilose at base. Capsules "IT-i" long on slender stipes half 

 as long to nearly as long as themselves. Stigmas 2, entire or 2-lobed. 



Var. a. tetrasperma proper ?

 cvenate-serrate with rounded base, thinlj' silky beneath, sec. n. 12-15 fine but 

 distinct and raised beneath. 



Santal Parg. ! Along streams, sometimes in thick forest. 



Var. i3. (In some respects this agrees better with S. acmopliyUa, Boiss.) 

 A. m.s. or large tree with narrowly lanceolate leaves serrulate or entire with 



cuneate or rounded base, quickly gl-abrescent, very white beneath, sec. n. as many

 Baskets are made from the branches. 



FAM. 127. CASUARINACEiE. 



Trees or shrubs with cylindric grooved jointed branchlets and leaves 

 reduced to subulate scales connate at base and forming short sheaths 

 at the nodes. FloAvers very minute, monoecious.* Males in slender 

 termijial spikes formed of numerous (finall}^) whorled subulate bracts 

 adnate to the rhachis, each bract subtending a flower consisting of 

 1-2 median scarious tepals and a pair of (lateral) bracteoles, stamen 



1 with short filament and large anther. Fem. in ovoid or globose 

 heads terminating abbreviated lateral branchlets, heads with whorls 

 (members of one whorl alternating with those of next so that the 

 bracts appear spiral, as they do in the very young male spikes) of 

 small bracts subtending pairs of very small, finally accrescent, lateral 

 bracteoles. Perianth 0. Ovary of 2 median carpels with an anterior 

 fertile cell and a posterior barren cell or the latter suppressed,! stigmas 



2 filiform very long. Ovules in the fertile cell 2, orthotropous, basal 

 or sub-basal. Fruits together forming a cone with the achenes 

 enclosed in the pairs of greatl}^ enlarged coriaceous or woody bracteoles 

 which open when the winged seed is ripe, wing terminal. Testa fused 

 with the wall of the achene, albumen 0. Cotyledons flat equal, 

 radicle very short, superior.
