 oles dilated and concave at the base, with several small 

 prickles: lfts. about 10-12 pairs, opposite or alternate, 

 oblanceolate, entire on the lower half but serrate or

aa. Petiole not prickly. 

 B. Species growing begone} the limits of the U. S 



integrifolia, Ait. Trunk 12-18 in. tall, erect, globular 

 or oblong: lvs. glabrous: lfts. alternate, 7-16 pairs, 

 oblong to linear-lanceolate to lanceolate, mostly ob- 

 tuse, entire or somewhat dentate towards the apex: 

 cones oblong and obtuse, short - peduucled. West 

 Indies. B.M. 1851. -The Florida plants, usually re- 

 ferred here, are apparently all Z. Floridana and Z. 

 pumila. 



Mexicana, Miq. Distinguished by DeCandoIle as fol- 

 lows: scales of the leaf-buds tomentose and also the 

 petioles at the ha»e, the petioles 3-cornered, unarmed, 

 glabrous, somewhat warty : lfts. of 9 or more pairs, 

 sub-opposite, narrow - lanceolate, straight or slightly 

 curved, acute or aeutish, rigidly coriaceous, dark green, 

 many-nerved, spinulose - serrulate from the middle to 

 the apex. Mex.— By Index Kewensis referred to Z. 

 Loildigesii, a species with prickly petioles. 



Pseudo-parasitica, Yates (Z. Rcezlii, Regel). Distin- 



f;uished as follows by DeCandoIle: trunk - cylindrical: 

 fts. lanceolate, sinuose - falcate, entire, glabrous, acute 

 at the base, cuspidate at the apex, with 18 strong nerves 

 which :ire twice bifurcate. Panama. — Grows on tree 

 trunks. 



angustifdlia, .laeq. Foliage glabrous when mature: 

 lfts. 5 in. long. 4-20 pairs, usually alternate, elongated 

 and narrowly linear, the apex obtuse and very obscurely 

 serrulate or entire, the base not narrowed, 6-8-nerved: 

 pistillate cone obtuse but cuspidate. Bahamas. Cuba. 



bb. Species native to Florida. 



Floridana, DC. Coontie. Comptie. Figs. 2768-71. 

 Lvs. ovate or ovate-lanceolate; petiole triangular in out- 

 line, sericeo-tomentose at base, with scattered hairs 

 above; lfts. mostly opposite, 14-20 pairs, glabrous above 

 anil with scattered hairs beneath, linear, falcate and 

 somewhat twisted, narrowed at the base and obtuse at 

 the apex, the margin revolute and with a few obscure 

 teeth: mature pistillate cones oblong, 5-6 in. (12-16% 

 cm.) long, markedly umbonate (projection on the 

 scales), densely tomentose. — Very abundant in southern 

 Florida on the east coast below lat. 26° 30', in open 

 comparatively dry pine woods. 



pumila, Linn. Differs, according to Webber, in hav- 

 ing shorter and broader leaflets which are less twisted 

 and not so erect and rigid, and in its shorter and non- 

 umbonate cones with seed-bearing scales thinner and 

 more flattened at outer end. — Abundant in central 



Florida, ranging from 28° 30' north for one degree of 

 latitude, in dense moist woods. 



Z. cordtlipcs, Versch., is Macrozamia spiralis.— 7.. Denni- 

 soni, F. Miiell.. is Macrozamia Peroffskyana.— Z. glaUca, Hort.

ZANNICHELLIA palilstris, Linn. (Jfaiadacew), or 

 Horned Pondweed, is offered by collectors of native 

 plants, but has little horticultural value. It is a hardy 

 aquatic plant (probably annual) widely distributed in 

 the New and Old Worlds. It has thread-like submerged 

 lvs. 1-3 in. long and flowers and fruits under water. It 

 is found in fresh or brackish water. B.B. 1:80.

ZAUSCHNERIA (named for a professor of natural 

 history at Prague). Onagracea. The California 

 Fuchsia, or Hummingbird's Trumpet, is a half-hardy 

 perennial plant %-2 ft. high, with drooping, trumpet- 

 shaped vermilion fls. l'A in. across and under 1 in. wide 

 at tin- mouth. It is the calyx which forms the showy 

 trumpet, and its 4 acute lobes are rather larger than 

 the 4 petals, which are obcordate and inserted at the 

 throat of the calyx-tube. The length of the calyx dis- 

 tinguishes this genus from Epilobium, to which Zausch- 

 neria is closely allied by reason of its 4 petals, 8 sta- 

 mens, 4-Ioculed ovary and comose seeds. The genus has 

 only one species, but this varies greatly in the width of 

 lvs. and hairiness. Varieties have been made based 

 upon linear, lanceolate or ovate lvs., but they run into 

 one another. The plants also vary from glabrous and 

 pubescent to tomentose. As a bedding plant it has been 

 occasionally used for novelty effects by European gar- 

 deners. To overcome its thin and leggy habit, it is well 

 to set the plants rather closely and pinch out the young 

 shoots until compact bushes are secured. The plant is 

 sometimes grown in pots for greenhouse decoration in 

 late autumn. There are said to be forms that vary con- 

 siderably in hardiness. The plant is hardy in most parts 

 of England with slight winter covering. In favored spots 

 it is considered to be a choice plant of pendent habit 

 for the steep sides of rockeries and for naturalizing on 

 old walls. In light and dry soils it spreads underground 

 like the epilobiums. It is prop, by division, by cut- 

 tings made in autumn and wintered in a coldframe, or 



2771. Aegreeate fruit of Z 



by seed* sown in early spring in mild heat. In Califor- 

 nia the plant is considered objectionable on account of 

 the unkempt appearance produced by the woolly seeds. 

 It is remarkably resistant to drought.
