GYMN6CLADUS (Greek, naked branch; referring to 

 the naked branches, which in winter are destitute of 

 twigs). Legumindste. A genus of 2 species, one of 

 which is a scarce native tree, the Kentucky Coffee Berry, 

 so called because its seeds were used fur coffee west of 

 the AUeghanies before and during the Revolutionary 

 War. It is a desirable shade tree for city streets, and is 

 especially interesting in winter. It is a clean, stout tree, 

 bright and graceful in appearance and free from disease, 

 growing from .SO-GO ft. high iu cultivation, and not leaf- 

 ing out until the middle of Way, after the other trees 

 are in full foliage. It is thornless and has compound 

 foliage. Grows with erect divisions, making narrow, pyra- 

 midal head. Branchlets very stout and destitute of 

 spray: fls. white, dioecious or polygamous, in terminal 

 racemes: pods long, hanging. Grows naturally in bot- 

 tom lands and richest soils. May be planted in any soil, 

 but thrives best in deep, rich, or rather humid soil. 

 Prop, by seeds and cuttings. 



Canadensis, Lam. (G.(7/'iiVa, C.Koch). Kentucky Cop- 

 fee Tree. Fig. lOU.S. Height in the wild, 7.3-100 ft. : lvs. 

 large, twice pinnate with i-7 pairs of pai-tial leaf-stalks, 

 each partial leaf-stalk with 5-l.'J ovate, acute Ifts., except 

 the lowest of 1 1ft., 1-3 in. long, standing edgewise. Ra- 

 cemes raany-fld. and elong.ited, nearly white, terminat- 

 ing branches of the season; staminate clusters 3-4 in. 

 long; pistillate 10-12 in., and compact: ovary sessile: 

 pods 6-10 in. long, flat, scythe-shaped, dark reddish 



habit, agreeing in the possession of naked sori, which 

 extend along the veins in various lines. A large num- 

 ber of the species are coated on the under surface with 

 a white or yellow waxy powder, which has given the 

 names of Gold Ferns or Silver Ferns. Two species occur 

 in the West, the "Golden-back" of California, and a 

 species less common from Arizona and other parts of 

 the Southwest. Over 80 species of wide distribution 

 have been included in the genus, which by many is di- 

 vided into a series of natural genera. The name Gym- 

 nogramma itself is probably not tenable.
