MOXOECIA POLYANDRIA. LXXXT 



FAOUS. STAM. FL. in globose clusters, pendulous on long pedun- 

 cles. Calyx campanulate, 5- or 6-cleft. PISTILL. FL. usually in 

 pairs, within an ovoid pedunculate involucre formed of numerous coal- 

 esced subulate flexible bracts, (7aZyr urceolate, the limb elongated, 

 4- or 5-cleft. Nuts ovoid-triquetrous, usually 2 in the coriaceous 

 muricate 4-valved involucre. ORD. XCII. CUPULIFERAE. p. 271. 



CORTLUS. STAM. FL. imbricated in cylindric aments ; scales 3-part- 

 ed, the middle segment covering the two lateral ones. Calyx 

 none. PISTILL. FL. in terminal clusters. Nut bony, roundish- 

 ovoid, subcompressed, solitary in the enlarged leathery-foliaceous 

 lacerate-dentate involucre. ORD. XCII. CUPULIFERAE. p. 272. 



CARPINUS. STAM. FL. Aments lateral, with simple ovate scale-like 

 bracts. Calyx none. PISTILL. FL. in pairs, with small deciduous 

 bracts, and enlarging foliaceous involucres, arranged in terminal 

 loose ament-like spikes. Calyx urceolate, the limb cup-like, dentic- 

 ulate. Nuts in pairs, bony, ovoid, subcompressed, striate-ribbed. 

 ORD. XCII. CUPULIFERAE. p. 273. 



OSTRYA. STAM. FL. nearly as in Carpinus. PISTILL. FL. solitary 

 or in pairs, in short slender terminal aments, with small caducous 

 bracts ; each flower (or pair of flowers) inclosed in a membranous 

 sac-like involucre, which enlarges and forms a bladdery closed bag, 

 in fruit, and these are imbricated in a strobile, like that of the 

 common Hop. Calyx somewhat urceolate, the limb tubular, entire. 

 Nuts solitary, compressed, lance-oblong. ORD. XCII. CUPULIFERAE. 

 p. 273. 



PLATANUS. STAM. FL. in small pendulous globose deciduous heads. 

 Stamens mixed with subclavate scales. PISTILL. FL. in larger pen- 

 dulous globose persistent heads. Fruit a clavate coriaceous nutlet, 

 beset at base by tawny pappus-like hairs. ORD. XCVI. PLATANA- 

 CEAE. p. 283. 



Order 8. Monadelpliia. 



Pixus. STAMINATE AMENTS spiked, subterminal. Stamens numer- 

 ous, inserted on the axis ; anthers subsessile, covered by the peltate 

 scale-like connective, the cells opening lengthwise. FERTILE AMEXTS 

 terminal, solitary or clustered, the carpellary scales with deciduous 

 bracts. Fruit a woody strobile, formed of the persistent imbricated 

 carpellary scales, which are thickened, and often mucronate at apex, 

 each scale with an excavation at base containing 2 naked nutlike 

 seeds, which are margined by a deciduous wing. ORD. XCVIII. 



COXIFERAE. p. 290. 



ABIES. STAMIXATB AMENTS scattered, or clustered near the ends of 

 the branches. FERTILE AMENTS lateral or terminal, the carpellary 

 scales with persistent, or evanescent bracts. Strobile with the scales 

 rounded, thin and not mucronate at apex, nor excavated at base. 

 Seeds with a persistent wing. ORD. XCVIII. CONIFERAE. p. 291. 



LARIX. STAMINATE AMENTS lateral and scattered, bud-like. FERTILE 

 AMEXTS lateral, the carpellary scales with colored persistent bracts. 

 Strobile erect, ovoid, the scales as in Abies, but somewhat exca- 

 vated at base. Seeds with a persistent wing. ORD. XCVIII.. 

 CONIFERAE. p. 292.
