 deeply cut. These plants are generally tre-ated as half- 

 hardy annuals, the seed being sown indoors in early 

 spring. The plants bloom in about ten weeks after being- 

 set out and continue in flower through July and August. 

 Some cultivators declare that this method is very un- 

 satisfactory and urge that the seed be sown in the au- 

 tumn and the young plants wintered in a coldfranie. 

 They will then begin to flower by June. The blossoms

Zaluzianskyas are more or less viscous jilants: lowest 

 Ivs. opposite, upi)er ones alternate, usually few-toothed: 

 fls. sessile but long-tubed, disposed in leafy spikes 

 which are cylindrical or flatfish; cal.yx 5-toothed, 2- 

 lipped or 2-parted ; corolla persistent, the 5 lobes entire 

 or 2-fid, equal or the 2 postex'ior ones a little wider; 

 stamens usually 4; style club-shaped: capsule oblong, 

 leathery or raerabranous. The Zaluzianskyas are little 

 known in American gardens. The botanical status of 

 the group is in need of revision. 



A promise was made to give some account under 

 Zalnzianskyaof the puzzling tradenames Erhnis ihi/iJrx. 

 fffiicilis. Paxtoniana -AnH speciotni. It is prrtl>al")le that 

 these are all varieties of ^riniis alp ht its. In the 

 American trade they are considered as trailing plants 

 suitable for hangiug-!:iaskets, vases and window boxi's, 

 uses to which Erinn.H alplmis is eminently adapted. 

 E. speciosa is said to have ultramarine blue fls. ; J'J. 

 gi-a oil is, light blue fls. and a spreading habit: U. Pus- 

 tonlana, pure white lis., blue-edged; A', duplex, donh]e 

 blue fls. MJrinns ijracilis of the botanists is a true 

 Zaluzianskya, beintr a synonym of Z. hjchniden, a plant 

 of erect habit with white fls. that are violet outside 

 Although Erinus and Zaluzianskya are placed in dif- 

 ferent tribes of the flgwort family, it is difficult to se]")a- 

 rate them by any one important botanical character un- 

 less it be the shape of the stamens, which is oblong in 

 Zaluzianskya, reniform in Erinus. The horticulturist, 

 however, may readily distinguish them by the lowest 

 leaves, those of the former being opposite, those of the 

 latter tufted. To the account of Erinus in Vol. II, p. 

 5-i!}, should be added the fact that the genus has only 

 one species. The other names which appear to be good 

 species of Erinus in Index Kewensis are presumably to 

 be referred to other genera, as they are mostly S.mtb 

 African plants, — Europe and the Cape 1 1 living few 

 genera in common.

 nately Bentham does not give the height of the plant or 

 color'of the fls. According to R.H. l"8ol:221, the plant 

 has white or lilac flower-clusters on the same plant, 

 each flower having an orange eye. The spikes, accord- 

 ing to Bentham, are commonly short and4-8-fld., some- 

 times long and 15-20-fld, There is some evidence that 



this species and the next are confused in the trade. In 

 R.H. 1851:221 the fls. are %-l in. long and less than 

 H in. across.

 (same picture as (in. 24, p. 89) the fls. are said to range 

 from white to lilac and darker depending upon their stage 

 of development, with an orange-colored eye which be- 

 comes crimson later. This suggests the preceding spe- 

 cies, and it is evident that the two must be distinguished 

 by technical characters until the colors can be verified. 

 The plant advertised in America as Nyeterinia selagi- 

 voides is said to be a pink-fld., half-hardy perennial, 

 growing 9 in. high, which does not agree with authentic 

 descriptions. A species passing under this name is 

 hardy at 8au Francisco. -^7 jj 



ZAMIA (name used by Pliny, meaning loss or dayn- 

 <n/e, and first applied to barren pine cones, and trans- 

 ferred to these plants apparently because of the cone- 

 like fructification). Cycaddcece. One of the nine genera 

 of the Cycas familj', as constituted by Alphonse De 

 Candolle (Prodr. 16, pt. 2, pp. 522-547). Other genera 

 of horticultural interest and discussed in this Cyclope- 

 dia are Ceratozamia, Cycas, Dioon, Encephalartos and 

 Macrozaraia. The Zaraias are stocky short- and usu- 

 ally simple-stemmed cycas-like plants, the trunk some- 

 times subterranean, with long-pinnate evergreen leaves 

 or fronds, the leaflets being thickened and usually 

 broadened at the base, and jointed. There are about 'AO 

 species in the American tropics, and two are native to 

 Florida. The flowers of cycads are dicecious, without en- 

 velopes; the pistillate flowers are mere naked ovules in- 

 serted under scales in cones, and the staminate flowers

are simple anthers under similar scales. The plants 

 are therefore ti'yninos[ierms (seeds naked or not inclosed 

 in a pericarp or ripened ovary) ami are allied to tiie 

 conifers. The fruit is a berry-like drupe. In Zamia the 

 floral scales are peltate (and imt horned) and form a 

 cylindrical cone; the anthers are numerous, and the 

 ovules pen<lulous in pairs. Leaves nearly straight in 

 venation. The fecundation of Zamia has been studied 

 by H. J. "Webber (Bull. 2, Bureau of Plant Ind. U. S. 

 Dept. Agr.). His conclusions respecting the Floridian 

 species are accepted below. 



Zamias are warmhouse plants, to be treated like spe- 

 cies of Cycas or Encephalartos, which see. The idants 

 are propatrated by means of seeds and offsets; also by 

 division when there is more than one crowm.
