434 Lvi. HALORAGBJ!. (C. B. Clarke.) IMyriophylhm. 



Leaves in the Indian examples sometimes whorled, more commonly in tufts of 1-3, 

 each tuft placed irregularly round the stem. The Australian M. vanABfolivm has the 

 leaves usually whorled ; but the whorls get broken and the Australian examples be- 

 come thus exactly like the Indian ; the frui); is altogether the same. — The correct 

 name of this plant is open to much question. De Candolle's is the oldest, but the 

 accompanying description was drawn up to fit Hottonia sessilijiora, Vahl St/mb. ii. 

 36 which probably was something altogether different ; then a MyriophyUum is dis- 

 covered in India which De Candolle's desorij)tion very fairly fits, and Hohenacker 

 and others apply it to the CandoUean name.

Glabrous slender annual herbs growing in moist places, or their branches 

 floating or submerged. Leaves opposite, linear- or obovate-spathulate, entire, the 

 upper ones often rosulate. Flower$ minute, asdllary, unisexual, usually monoecious, 

 solitaiy, or sometimes one male and one female in the same axil simulating a 

 hermaphrodite flower ; achlamydeous ; bracteoles white, membranous, linear- 

 oblong, very cad.ucous. Maie : stamen 1. Femais : ovary 4-ridged 4rce]led ; 

 styles 2, elongate, stigmatose their whole length ; ovules solitary in each cell, 

 pendulous. Fruit coriaceous, indehiscent, 4-seeded, the 4 carpels at length 

 separating. — Distetb. Species 1 or 2 found almost all over the globe ; but some 

 authors allow 10 or 20 species. 



[The distribution of such critical species as these CalUtriches cannot be safely 

 stated; there are examples collected in Sikkim, alt. 8000-9000 ft., by Sir J. D. 

 Hooker which are probably C. verna (and not C. stagnalis), but they show no fruit.]

Trees or shrubs. Leaves opposite, stipulate (except AnisophyUea), usually 

 coriaceous, glabrous ; stipules interpetiolar, very caducous. Flowers axDlaTy, 

 usually bisexual, surrounded at the base with connate or cupuliform bracts or 

 ebracteate. Calyx more or less adnate to the ovary (except Blepharistemma) ; 

 limb produced beyond the ovary, 4-14:-lobed ; lobes valvate, persistent. Petals 

 equal in number to the sepals, entire emarginate 2-fld or lacerate. Stamens 

 usually twice the number of petals, in pairs opposite to and embraced by them, 

 raiely indefinite (Kandelia) ; anthers 2-celled, rarely multi-loceUate (Sh^ophora). 

 Ovary from 5- to l-celled by solution of the septa ; styles connate (except in
