3. LIRIODE'NDRON, L. Tulip Tree. (Gr. Xeipiov, a lily ; devdpov, 

 a tree.) Sepals 3, reflexed, caducous ; petals 6, erect ; carpels imbricated 

 in a cone, 1 — 2-seeded, indehiscent and attenuated at apex into a lance- 

 olate wing. — Tree, -with showy, bell-shaped, upright flowers. Vernation 

 induplicate. Stipules large, oval, caducous. In the bud, each leaf 

 bonds inward to an inverted position, infolds all that is within it, and is 

 in itself infolded by its pair of stipules and by the pext lower loaf, and 

 so on. as seen in Fig. 000 



Ii. tulipifera. Tulip Tree. "WmTE-WooD. Poplar. A fine tree, one of 

 most remarkable of the American forests, Can. to La., especially abundant in 

 the Western States. It is ordinarily about 80f high, with m, diam. of 2 or 3f, 

 but along the Ohio and Miss, rivers it grows much larger. Near Blooming-ton, 

 Ind., we measured a tree of this species which had been recently felled. Its cir- 

 cumference 4f from the ground was 23f; 30f from the ground its diam. was 

 5f ; the whole bight 125£ The trunk is perfectly straight and cylindric. At 

 top it divides abruptly into coarse, crooked, rather unsightly branches. Lvs. 

 dark-green, smooth, truncate at the end, with 2 lateral lobes, 3 — 5' in length and 

 breadth, on long petioles. In May and June it puts forth numerous campanulate 

 flowers, greenish yellow, orange within, solitary, broader than the tulip, and 

 erect. The wood is extensively used as a substitute for pine. 



Order III. ANONACE^. Anonads. 



Trees or shrubs with naked buds, entire, alternate lvs. destitute of stipules. Fls. 



usually green or brown, axillary, hypogyno'us, valvate in sestivation. Sepals 3 ; 



petals 6, in two circles, sometimes coherent. Stamens oo, with an enlarged con- 



neotile, short filament, and large torus. Ova. several or oo, separate or coherent, 



fleshy or not, in fruit. Embryo minute in the end of ruminated albumen. 



Genera 20, epeciee 300, chiefly natives witliin the tropics of both heniispliercs. Four species 

 are found witliin the limits of the Unitefl Stales, sill of tho following genus. TJie Anonads are 

 generally aromatic in all their parts. Their pulpy fruit, as the custard apples, are sweet and 

 esculent. ■ 



ASIMINA Adans. Papaw. Fig. H3. Sepals 3, petals 6, the outer 

 row larger than the inner ; stamens densely packed in a spherical mass ; 

 pistils several, distinct, ripening but few, which become large, oblong, 

 pulpy fruits ^with many flat seeds. — Shrubs or small trees, with brown- 

 ish, axillary, solitary flowers. 



* Flowers appearing before the leaves Nos. 1, 2. 



* Flowers .appearing with the leaves Wos. 3, 4. 



1 A. triloba Dunal. Lvs. dbovate-oblong, acuminate ; pet. dark purple, exterior 

 orbicular, 3 ori times as long as the sep. — A small and beautiful tree, 15 — 20f high, 

 on banks of streams, Mid., Southern and "Western States. Branches and lvs. nearly 

 glabrous, the latter 8 — 12' by 3 — 4', very smooth and entire, tapering to very short 

 petioles. Fls. 1' broad, precocious. Fr. about 1' thick and 3' long, ovoid-oblong, 

 about 8-seeded, yellowish, fragrant, eatable, ripe in October. Pis. in March, Apr.

2 A. parvifldra Dunal. Lvs. dbovate-oval, acuminate; pet. greenish-purple, the 

 outer oval, hardly twice the length of the sep. — "Woods near the coast, from Car. to *v, 

 Pla. and La. Shrub 2 — 3f high, smaller every way than No. 1. Lvs. about half ' 

 as large, glabrous, obtuse-pointed, tapering to the base. Fls. less than half as ' 

 large, opening while the branches are naked. Fr. roundish, about 1' long. May. 



3 A. grandiflora Dunal. Los. obovate-oblong, obtuse, grayish-tomentous both^
