102 MONOCOTYLEDONS. GRAMINE^. AnthoTantllUlH, 



rally consiflerably elongated before the radicles are protruded. 

 ' The inferior end of the Embryo pierced by the radicles, which 

 • were inclosed in its sul)stance, and remaining under the form 



of a rim or short sheatk surrounding the base. 

 Vegetation, Stem cylindrical, increasing by addition to its centre 



with no perceptible diiTerence of structure between the bark 



and the wood. Leaves alternate, often sheathing ; with close 



parallel nerves, and minute transverse veins. 



Order I. GRAMINE.E. Jms. 



Glume (cah/x Linn.) I — 2- or many-flowered, mostly of 2 valves, 

 . rarely of 1 or v.anting. Perianth {corolla Linn.) ghimaceou<, 

 1 — 2-valved. Stamens hypo^ynon^. ylnlhers vtrmlWe. Ovary 

 superior, with one ovule. Styles 2, rarely I or 3. Stig7?ws 

 plumose. Pericarp a Caryopsis, or Ufrictilus. Embryo 

 scutelliform, lateral, on the outside of the base of a farinaceous 

 copious albumen. Plumule naked. Stems fistulose, generally 

 simple and herbaceous, sometimes branched, rarely shrubby. 

 Leaves one to each joint, with a sheath slit longitudinally on 

 one side, having a membranous appendage (ligule) at its sum- 

 mit. Flowers small, panicled or spiked. Br.

Cul. of two valves, 2-flovvered ; the inferior valve very small. 

 Flowers dissimilar; the inferior imperfect, of one or two 

 valves; the superior perfect, 2-valved; ^ecJ invested with the 

 permanent hardened perianth.

■^ The paijes thus lefened to, after each specific character, throughout 

 the mono- and dlcotijlcduiwus plants, are in the first Part of this Flora, where 

 fuller descriptions and more particular habitats are given ; both of which it 

 was deemed unnecessary to repeat here. 



^ The character ot this genus is so different from that which we have 

 given of it in the first part of this work, that it ^vill be unintelligible to 

 students without some further explanation. It is therefore to be observed, 

 that wliat are here termed the two lower imperfect t'orets, are in our character 

 at p. 3, called the two outer valves of a double perianth, in confonnity to 

 the general mode of describing it, adopted by botanists of the Linnfean school.
