in the female, but with perfect stamens.—Aquatic floating herbaceous plants, 
having their upper part emersed while flowering. Leaves usually opposite or 
verticillate. Flowers small, verticillate in the axils of the floral leaves: the 
upper usually male, the lower female, and the intermediate ones sometimes 
bisexual. 
1047. (1) M. Indicum (Willd.:) leaves in fours, verticellate ; lower ones 
divided in a pinnated manner into capillary lobes ; upper gradually narrower 
and pinnatifid with the undivided portion broader; uppermost cuneate-lan- 
ceolate, toothed or almost quite entire: flowers verticellate, monecious: 
stamens 8; anthers oblong: female flowers with 4 petals: carpels rugose 
and tubercled, cohering at the axis.— Willd. sp. 4. p. 407 ; DC. prod. 3. p. 68 ;

We have no doubt of our plant being the same as that sent from the 
Madras herbarium to Willdenow, although he states that Klein had observed 
the flowers to be bisexual: in the quotation, however, from Klein's descrip- 
tion, we do not observe any thing to warrant that inference: in all our spe- 
cimens the upper flowers are male. 
, 1048. (2) M. tetrandrum (Roxb. :) leaves verticellate, lower ones divided 
1n à pinnated manner into capillary segments ; upper ones much the smaller, 
pinnatifid : flowers verticellate, moncecious: stamens 4 : carpels nearly smooth 
and even, blunt on the back.— Roxb. fi. Ind. 1. p. 451 ; (ed. Wall.) 1. p. 470;

Subord. 9. CALLITRICHINE® (Link.) Calyx exceedingly minute, 
inconspicuous, surrounding the ovarium, soon rupturing. Petals want- 
ing. Stamens 1, rarely 2: filament filiform, grooved in the inside: 
anther reniform, 1-celled, bursting transversely. Ovarium solitary, 
tetragonal, compressed, 2-celled (of two carpels, the dorsal sutures 
being slightly inflexed towards the axis): ovules in pairs, peltate : 
styles none: stigmas 2, filiform, pappulose on their inner surface. 
Fruit 2-celled, contracted at the dorsal sutures, at once loculicidal and 
septicidal (thus as if composed of four achenia, attached round the base 
of the stigmas by the centre of their inner angle). Seeds, 2 in each 
cell, divaricating (or in each achenium solitary), peltate. Embryo 
slightly curved in the axis of a thin fleshy albumen: radicle superior, 
long : cotyledons very short —Aquatie herbaceous plants. Leaves 
?PPosite, simple, entire. Flowers axillary, very minute, usually uni- 
Sexual, sometimes with two small bractez at the base of the short 
peduncle, . "
