Sub-Order. CERATOPHYLLE.E. 
Ceratophylle®, DC. Prodr. 3. 73. (1828); Lindl. Synops. 225. (1829). 
Essential Character. — Flowers monoecious. Calyx inferior, many-parted. Male : 
Stamens from 12 to 20; filaments wanting; anthers 2-celled. Female: Ovary superior, 
1-celled; ovule solitary, pendulous; stigma filiform, oblique, sessile. Nut 1-seeded, inde- 
hiscent, terminated by the hardened stigma. Seed pendulous, solitary ; albumen 0 ; embryo 
with 4 cotyledons, alternately smaller ; plumula many-leaved; radicle superior. {DC .) — 
Floating herbs, with multifid cellular leaves. 
Affinities. In consequence of tlie number of its cotyledons, Richard 
placed this order near Coniferse, with which it seems to have no kind of 
affinity. De Candolle urges its relation to Hippuris and Myriophyllum, among 
Halorageae, from which it differs in its superior ovary ; and he inquires whe- 
ther Naias, which, according' to some, is dicotyledonous, does not belong to 
the same order. Agardh places it among Fluviales. Surely it is better to 
consider it a degeneration of Urticaceae, to which so many of its characters 
refer it, and as bearing the same relation to them as Podostemaceae and 
Callitrichaceae to some unkno\\Ti order, or as Pistiaceae to Araceae. 
Geography. Found in ditches in Europe. 
Properties. Unknown.

Ulmace®, Mirbel Elem. 905. (1815); Lindl. Synops. 225. (1829.) — Celtide®, Rich.; 
Gaudich. in Freyc. Voy. 507. (1826). 
Essential Character. — Flowers hermaphrodite or polygamous, never in catkins. 
Calyx divided, campanulate, inferior, irregular. Stamens definite, inserted into the base of 
the calyx ; erect in aestivation. Ovary superior, 2-celled ; ovules solitary, pendulous ; 
stigmas 2, distinct. Fruit 1- or 2-celled, indehiscent, membranous or drupaceous. Seed 
solitary, pendulous ; albumen none, or in very small quantity ; embryo straight or curved, 
with foliaceous cotyledons ; radicle superior. — Trees or shrubs, with scabrous, alternate, 
simple, deciduous leaves, and stipules. 
Affinities. Nearly related to Urticaceae, from which they are only dis- 
tinguishable by their 2 -celled fruit and hermaphrodite flowers ; they are often 
combined with that order. 
Geography. Natives of the north of Asia, the mountains of India, China,
