Series IV. Glumiflore. Flowers in heads or spikelets, in- 
vested by imbricate bracts. Perianth wanting or reduced to minute 
bristles or scales. Ovary superior, 1-celled and 1-ovuled, or divided 
into several 1-ovuled cells or distinct carpels. 
LXXXIX. Centrolepide. Flowers hermaphrodite or poly- 
gamous. Perianth wanting. Stamens 1 or 2; anthers versatile. 
Ovary either 1-celled or collaterally 2-3-celled, or of several distinct

almost moss-like; leaves linear or filiform. (p. 755.) 
XC. Restiaceze. Flowers unisexual. Perianth of 6 scarious 
leaflets. Stamens 3. Ovary 1-3-celled; ovules solitary in each 
cell, pendulous. Fruit nucular or capsular.—Stems solid, terete ; 
leaf-sheaths split to the base. (p. 759.) 
XCI. Cyperacez. Flowers hermaphrodite orunisexual. Perianth 
wanting or represented by minute hypogynous scales or bristles. 
Anthers basifixed. Ovary 1-celled. Fruit compressed or trigonous. 
—Stems usually solid and trigonous ; leaf-sheaths entire. (p. 762.) 
XCII. Gramineze. Flowers hermaphrodite or rarely unisexual. 
Perianth wanting or represented by 2 minute scales. Anthers 
versatile. Ovary l-celled. Fruit grooved down one side.—Stem

Susxinepom II]. CRYPTOGAMIA. 
Plants not bearing true flowers—that is, having no stamens nor

Grasset... PTERIDOPHYTA. 
Plants usually furnished with roots, leaves, and stems; in all 
cases containing well-developed vascular tissue. Reproductive 
organs composed of sporangia or spore -cases, containing micro- 
scopic spores, which on germination develop a prothallium. 
XCIII. Filices. Sporangia minute, placed on the margin or 
under-surface of the leaf or frond, rarely somewhat larger and 
arranged in spikes or panicles. Spores all of one kind.—Fronds 
circinate in vernation (except in the suborder Ophioglossacee). 
(p. 925.) 
XCIV. Marsileaceze. Sporangia of 2 kinds, macrosporangia 
and microsporangia, enclosed together in the cavities or cells of 
globose sporocarps near the base of the fronds. Macrosporangia 
containing a single macrospore; microsporangia with numerous 
microspores.—Marsh plants, usually of small size; fronds circinate 
in vernation. (p. 1030.)
