CI. 2.] GRAMINEiE. 69 



or divided Stigma. Seed in both instances solitary, 

 either naked, or frequently covered with the per- 

 manent hardened inner valve of the Calyx (Corolla 

 of Linnaeus). Embryo small, attached laterally to 

 the base of a much larger farinaceous Albumen. 

 The lobe of the Embryo, in germination, remains 

 with the annexed Albumen, sessile, connected at one 

 side with the primary sheath which surrounds the 

 Plumula (62 : 1). Roots fibrous, capillary. Culms 

 cylindrical, either hollow or pithy, knotty or jointed ; 

 generally herbaceous, and unbranched. Leaves al- 

 ternate, simple and undivided, springing solitary 

 from each knot, sheathing; the Sheath split down to 

 the knot. Flowers either tufted, or spiked along a 

 linear Receptacle, or Rachis, or panicled; concealed 

 while young in the sheath of the uppermost Leaf. 

 Some species become, by abortion, monoecious." 



A great and well-known family, distributed into 

 ] 3 sections, by the number of the Styles, Stamens, 

 and Florets. Examples are, Anthoxanthum ; Alope- 

 curus, Panicum, Agrostis; Holcus; Cenchrus, Rott- 

 bollia; Air a, Melica; Dactylis ; Sesleria, Elymus, 

 Triticum ; Bromus, Poa, Glyceria, fig. 3, 4, Briza, 

 Arundo; Oryza, Ehrharta; Nardus, Apluda, Zea; 

 Pharus, Cornucopia, Coir, fig. 141 ; Nastus; Pari- 

 ana. " The habit, chaffy flower, single seed, mealy 

 albumen, situation of the embryo, and mode of ger- 

 mination, render this Order peculiarly distinct." — ■
