 fertilized, or the lower leaves will suffer and finally die, 

 thus detracting much from the elegance of the speci- 

 men. They all grow naturally in rich black soil, but they 

 all thrive exceedingly well in the sandy pine-woods soil 

 if well fertilized and watered; in fact, they can hardly 

 be fertilized too much, and the more nitrogenous manure 

 and water they get the faster they grow. When trans- 

 planted they must be set deep. In planting palms make 

 a hollow about 6 feet in diameter and about 2 feet deep 

 in the center. This center, which receives the plant, is 

 the deepest point, while the ground all around is 

 slightly sloping. Care must be taken to remove the 

 sand after heavy rains or the crown will soon be buried 

 and the little plant dies. As the palm first forms the

trunk in the soil and as the growth is rather rapid, this 

 precaution is not necessary after the plant has attained 

 a few feet in size. (H. Nehrling.) 



A. Trunk evident, usually tall. 



B. Foliage very glaucous. 



uresana, Trel. (Inbdes uresdna, Cook). Trunk 15- 

 35 ft. high and upward of 1 ft. diam.: Ivs. glabrous, 

 very glaucous ; petiole stout, concavo-convex, unarmed, 

 about 40 in. long, nearly 1 in. wide and nearly %in. 

 thick; blade about 40 in. long and wide, multifid, with 

 coarse straw-colored fibers from the sinuses, the center 

 arcuately recurved: fr. of a single developed carpel, 

 depressed globose, %in. or less in diam., edible, green, 

 or when dry dingy brown and somewhat glossy, the 

 mesocarp then cottony; endocarp whitish straw-color, 

 glossy within; seed polished, dark chestnut-brown, 

 labyrinthiform-rugose, much depressed. Sonora, Mex., 

 in the vicinity of Ures; intro. to cult, in S. Calif. R.H. 

 1910, p. 59. Described and figured in vol. 12 (1901) of 

 Kept. Mo. Bot. Gard. "From the two arboreous pal- 

 mettos of the United States, S. uresana differs markedly 

 in its pale, very glaucous foliage, and in the size of its 

 fruit, which is of thrice the diameter of that of S. Pal- 

 metto, and usually a third larger than in S. mexicana, 

 with the former of which species it agrees in having but 

 one of the three carpels developed and fertile while in 

 S. mexicana two or even all three are not infrequently 

 developed. Considering the extent to which this section 



of Mexico has been visited by collectors of seeds it 

 would be remarkable if this attractive plant should 

 not prove to be already in cultivation in European 

 gardens." 



BB. Foliage green or essentially so, at least above. 

 mauritiaefSnnis, Griseb. & Wendl.; also spelled 

 mauritiiformis. Trunk middle-sized, but occasionally 

 attaining 60-80 ft.: Ivs. finally 12 ft. across; blade 

 suborbicular, longer than the petiole, glaucous beneath, 

 multifid to the middle, with loose fibers between the 

 bifid lobes: spadix very long and much branched, 

 appearing below the Ivs.: fr. globose or inverted pear- 

 shaped, about 1^ in. long. W. Indies. The name 

 mauritiseformis does not appear in the American trade, 

 but S. glaucescens, Lodd. and Hort., probably belongs 

 here, according to Grisebach. Nehrling writes: "S. 

 glaucescens of the trade rivals S. Blackburniana in 

 beauty and rapidity of growth. Its Ivs., though smaller, 

 have a beautiful bluish green color." 



Palmetto, Lodd. (Inbdes Palmetto, Cook). CABBAGE 

 PALMETTO. Fig. 3516. St. erect, 20-80 ft. high: lys. 

 5-8 ft. long, cordate in outline, recurved at the summit, 

 shorter than the petiole; segms. deeply cleft: spadix 

 spreading, shorter than the Ivs.: drupe black, ^-K m - 

 long. N. C. to Fla. and Bahamas. S.S. 10:507. A.F. 

 12:628. S. Mocinii, Hort., is referred to S. Palmetto by 

 Voss, but Nehrling describes it as a stemless 

 plant from Mex., more beautiful than the dwarf 

 palmetto, bearing immense Ivs. on strong 

 stalks, the Ivs. attaining a height of 6-8 ft. 

 Others think S. Mocinii is the same as S. 

 Blackburniana. S. Palmetto has been confused 

 in the European trade with S. texana. Very 

 commonly planted as a shade and avenue 

 tree in the southern states. 



Blackburniana, Glazeb. (S. umbraculifera, 

 Mart. Inbdes Blackburniana, Cook) . St. 30- 

 40 ft. high, thickened at the middle: blade 

 ample, orbicular, glaucous, rather rigid, 

 shorter than the petiole; lobes ab9ut 40, ensi- 

 form, bifid, filamentous, rather rigid: spadix 

 more branched than in any other species: fr. inverted 

 pear-shaped, about 1^ in. long. W. Indies. G.F. 

 4:307. G.C. II. 2:777. Loudon's Gard. Mag. 5: 52-7, 

 with several figures. R.B. 35, p. 189. 



causiarum, Becc. (Inbdes causidrum, Cook). PORTO 

 Rico HAT-PALM. YARAY. Trunk to 40 or 50 ft. and 

 2 ft. thick, columnar or nearly so, light gray or nearly 

 white: If .-bases splitting into fibers and more or less 

 remaining as long ribbons: Ivs. about 12 ft. long, 

 the blade and petiole about equal in length but both 

 surpassed by the infl., the petiole keeled near the end 

 above: fr. J^-^in. diam., grayish, with a finely rugose 

 or nearly smooth chestnut-brown seed. 



texana, Becc. (S. mexicana, Auth., not Mart. Inbdes 

 texana, Cook). Robust palm, to 50 ft. and 2% ft. diam. 

 of trunk which is bright reddish brown: Ivs. 5-7 ft. 

 across, shining and yellowish green, the segms. often 

 parted and filamentose, the petiole stout and equaling 

 or exceeding the blade: terminal branchlets of infl. 

 slender: seed about 3^in. broad, with a prominent 

 micropyle. S. Texas. S.S. 10:508. 



exul, Bailey (Inbdes exul, Cook). A strong vigor- 

 ous tree with large crown of vivid green Ivs., and green 

 trunk due to the color retained in the sheathing lf.- 

 bases: Ivs. otherwise much like those of S. texana: 

 branchlets of infl. thickened: fr. solitary, with large 

 seed not wrinkled above nor hollowed below. 

 Described from handsome trees planted at Victoria, 

 Texas, probably native of Mex. Hardy and promising, 

 princeps, Hort. Large species with a stout trunk 

 which is covered with the persistent bases of the old 

 Ivs.: Ivs. very large, about 5 ft. long; blade divided into 

 about 100 segms., chartaceous, green; segms. all
