^ Species. 1. l.floridanum. 2. parviJloriim.-~Kn Ame- 

 rican genus with ttie exception of /, anisatum of Japan 

 and China. 



379. MAGNOLIA. L. 



Calix 3-Ieaved. Fetals 6 to 9. Capsules 2- 

 valved, 1 -seeded, imbricated in a cone. Seeds 

 pendulous, arillate.

 matic; leaves alternate, entire and large, partly ovate, in 

 some species auriculate at the base, at first closely sheath- . 

 ed by the stipules; flowers large and terminal, fragrant, ,

Species. 1. M. grar.difora. The most magnificent 

 tree of the southern states, the trunk often presenting a 

 living column of 80 or 90 feet elevation, almost unob- 

 structed by branches, and terminated by a spreading top 

 of the deepest perennial verdure. 2. g-iaiica. 3- macro- 

 phylla- This small pyramidal tree produces tlie largest ^ 

 leaves and flowers of any other North American plant. 

 'J'he limits of this interesting species appear to be ex- 

 tremely local. I first observed it in Tennessee near the 

 tanks of Cumberland river, but of very small size. In 

 the southern states it is not at present known to the most 

 assiduous collectors in any other spot than a single nar- 

 j'ow tract of about 2 miles'in length, 12 miles south-east 

 of Lincolnton (Lincoln county. North Carolina); these li- 

 mits 1 have carefully examined and found them invaria- 

 ble. 4. ^r//)f/«/«, (Umbrella-tree.) S.caiminata. (Cucum- 

 ]jer-trce.) Flowers yellowish green. 6. cordata. Flow- 

 ers yellow; appearing twice in the year in the garden of 

 Mr. Landreth of Philadelpl»ia. Leaves subcordate-oval, 

 never truly cordate. 7. aiiriculata. Leaves rhomboid- 

 lanceolate, auriculate at the base. Considerably allied to 

 Jf. macvophyiJa , fi. pijranudata. Nothing more than a va- 

 riety of the preceding, having leaves ahttie broader and 

 shorter. 



A genus of about 15 species, almost exactly divided 

 between China and the United States; there is also 1 spe- 

 cies in tropical America.
