CYCLOSTEMON MACROPHYLLTJS. (Nat. order EuphorbiaceEe.) 



CyCLOSTEMON. Blame.— GEN. CHAR. Dioecious. Calyx deeply 4-5 parted, segments imbricate, petals 0. Male, disk concave large naked 

 in the centre or with a minute rudiment of an ovary. Stamens 4-40 inserted round the margin of the disk, filaments free erect, anthers oblong ovoid or 

 ellipsoid introrse or dehiscing down the outer edge, fixed to the filament at the middle of the back, the connective not produced. Female, ovary seated on a 

 small disk 2-4 celled, 2-4 sulcate, cells 2 ovuled, ovules collateral pendulous, styleB as mauy as ovary-cells connate at the base, nearly obsolete or filiform, 

 stigmas broad triangular and deeply 2-lubed or narrow and linear. Fruit indehiscent more or less fleshy with 2-4-crustaceous cocci. Seed compressed, 

 with a caruncle, albuuieu copious fleshy, cotyledons plane foliaceous, radicle very small superior. Trees, leaves alternate simple penniveined entire or 

 toothed coriaceous, stipules deciduous. Flowers fascicled from tubercles in the axils of the leaves or from old axils. Blume Bijd. p. 597. Sphragidia,

DeCandolle divides this genus into 3 Sections as follows : — 



1. Dodecastemon. — Ovary 3-4 celled, styles 3-4 filiform. 



2. Stenogynium. — Stamens few, ovary 2-celled, stigma sublinear entire peltately dilated at the apex. 



3. Bucyclostemon. — Stamens many, ovary 2-celled, stigmas broad 2-lobed. 



The following species belongs to the 3rd Section, 



CYCLOSTEMON MACBOPHYLLUS. (Bl.) A large tree of no great height but with a very thick trunk and branchea 

 spreading in every direction, ramuli terete and with the gemmae tomentose, leaves very coriaceous entire or with a few distant 

 serratures sometimes prominent but often inconspicuous, oblong to lanceolate, acuminate at the apes, 4-12 inches long by 2-4J 

 inches broad, glabrous in age but when young more or less furnished with a deciduous brown tomentum, petioles 3-4 lines long, 

 veins and veinlets very prominent beneath, stipules small erect lanceolate deciduous, flowers fascicled in the a.-rjl a or at the old 

 axils (shortly pedicelled or) sessile on the tubercles, densely velvetty outside, males 3-8 together or rarely solitary, females solitary 

 or 2-3 together. Male, calyx 4-5 parted 8-9 lines in expansion, segments equal concave rounded, stamens 35-40, rudiment of ovary 

 minute or wanting. Female, ovary strigose seated on a disk which is hid in the pubescence, stigmas 2 subsessile each deeply 2- 

 lobed, the segments triangular with a broad 3-cleffc apex and narrow base, fruit globose about 1 inch in diameter. Bl. Biji. p. 

 598. Sphragidia Zeylanica, Thw. I. c. 



Var. p. sessiliflora. — Flowers sessile. 



This tree is very common in. the dense moist forests of the Anamallays 2000-4000 feet elevation, and in Coorg {the water-falls near 

 Mercara), iWOfeet, and I have it from other parts of our Western ghats, Tramncore, &c, and it is found in Ceylon and Java. All my Indian 

 specimens have the flowers sessile and the leaves occasionally serrated, though often quite entire, and the petioles do not exceed 4 lines in length ; 

 in these points only does it differ from the Ceylon tree, so that it cannot, I think, be more than a variety ; the timber is very hard but quite unknown.
