places, particularly along streams in the Coast Range 

 foothills and mountains, and attaining its greatest size 

 in the cool fog-moistened alluvial valleys of the coast of 

 N. Calif, and S. Ore.; it is but rarely seen in the drier 

 interior valleys of the state. It often crowns the highest 

 points of the coast-range hills, up to about 2,500 ft. 



altitude and far from 

 the nearest spring or 

 other visible sign of 

 moisture, but in such 

 cases the rock strata 

 are nearly vertical 

 and easily penetrated 

 by the long roots 

 which are able thus 

 to reach hidden sup- 

 plies of water. In 

 such places it usually 

 forms dense clumps 

 or thickets of shrubs 

 or small trees which 

 are frequently shorn 

 by the cutting ocean 

 winds as though by 

 a gardener's shears, 

 suggesting its adap- 

 tability for clipped- 

 hedge and windbreak 

 work. It is used in 

 boat -building, for 

 jaws, bits, cleats, 

 cross-trees, and the 

 like. The branches 

 are occasionally used 

 for poles for chicken- 

 roosts, as the strong 

 odor pervading wood 

 and bark as well as 

 Ivs., is said to keep 

 away lice. The Ivs. 

 are used for flavor- 

 ing soups and blanc- 

 manges but are too 

 strong to give as 

 agreeable flavor as 

 those of Laurus 

 nobilis or Prunus 

 Laurocerasus. The 

 tree is sometimes cult, 

 for ornament in S. 

 European parks and 

 gardens. Sargent de- 

 scribes it as "one of 



3884. Uniola latifolia. (XK) the stateliest and 



most beautiful in- 

 habitants of the North American forests, and no 

 evergreen tree of temperate regions surpasses it in the 

 beauty of its dark dense crown of lustrous foliage and 

 in the massiveness of habit which make it one of the 

 most striking features of the California landscape and 

 fit it to stand in any park or garden."

UNGNADIA (named for Baron Ungnad, who in 1576 

 introduced the common horse-chestnut to western 

 Europe by sending seeds to Clusius at Vienna). Sapin- 

 dacese. MEXICAN BUCKEYE. Small tree or shrub which 

 has been grown abroad in the coolhouse, but is hardy in 

 the S. U. S., where it is used as an ornamental. Lys. 

 alternate, without stipules, odd-pinnate; Ifts. 3-7 pairs, 

 serrate, terminal long-petioled: fls. polygamous, irregu- 



lar, aggregated in lateral fascicle or corymbose; calyx 

 subequal, campanulate, 4-5-parted, lobes imbricate; 

 petals 4^5, subequal, clawed, apex connate-cristate; 

 disk 1-sided, oblique, tongue-shaped; stamens 7-10, 

 unequal in length; ovary stipitate, ovoid, 3-celled: caps. 

 3-lobed, loculicidally 3-valved, leathery, cells 1-seeded; 

 seed emetic. One species, Texas. The seed, or "bean," 

 has a sweet taste, but is considered emetic and poison- 

 ous. The fr. does not have a prickly husk like the horse- 

 chestnut. 



speciosa, Endl. MEXICAN BUCKEYE. Commonly a 

 slender deciduous shrub, 5-10 ft. high or sometimes 

 a small tree: wood brittle: Ivs. alternate, odd-pinnate; 

 Ifts. 5-7, ovate-lanceolate, acuminate. Common in 

 S. W. Texas; winter-kills in N. Texas at a temperature 

 of zero. S.S. 2:73. F.S. 10:1059. Gn. 19, p. 309.

UNIOLA (an ancient Latin name of some unknown 

 plant, derived from unio, unity). Graminese.. Peren- 

 nials with loose usually showy panicles: spikelets broad 

 and very flat, several-fld., some of the lower lemmas 

 empty; glumes and lemmas keeled, nerved, pointed, but 

 awnless. Species 5, all American. Cult, for the orna- 

 mental panicles, which are suitable for dry bouquets. 



latifdlia, Michx. SPIKE-GRASS. Fig. 3884. Culms 

 2-4 ft.: Ivs. broad and flat, often 1 in. wide: spikelets 

 large and thin, at maturity drooping on slender pedicels, 

 forming a very graceful and ornamental panicle. Pa. 

 to Kans., and southward. Often grown in hardy 

 borders. One of the best of our hardy native perennial 

 grasses. 



paniculata, Linn. SEA OATS. Fig. 3885. Culm 

 taller, 4-8 ft.: Ivs. narrow and convolute: spikelets 

 narrower, upright on short pedicels, forming an elon- 

 gated drooping 

 panicle. Sand-hills

UNONA (in imi- 

 tation of Anona). 

 Annonaceae. A 

 genus based by the 

 younger Linnseus 

 on an American 

 plant belonging to 

 the previously 

 established genus 

 Xylopia, and 

 afterward incor- 

 rectly applied to 

 the Old World 

 genus Desmos, of 

 which it becomes 

 a synonym. U. dis- 

 color, Vahl, cult, 

 in tropical gar- 

 dens for its sweet- 

 scented fls., is 

 identical with the 3885. Uniola paniculata.
