ZALACCA (said to be the name of the genus in the Three of the species are known as night balsams or 



Moluccas). Palmdcese. Stemless palms with creeping star balsams, from their night-blooming habit. The 



roots, adapted to the warmhouse. Lvs. elongated, name night-blooming phlox would be better, as the 



equally pinnatisect; segms. alternate, fascicled or flowers are salver-shaped and five-lobed, each lobe being 



equidistant, lanceolate or oblanceolate, straight or fal- deeply cut. These plants are generally treated as half- 



cate, acuminate; rachis obtusely 3-angled, not pro- hardy annuals, the_seed being sown indoors in early 



duced into a spine; petioles rather terete, 

 usually with spirally disposed prickles; 

 sheaths strongly armed with compressed 

 prickles; ligule none: spathes persistent, the 

 lower ones sheathing the peduncle and 

 branches, incomplete, the partial ones sub- 

 tending the floriferous branchlets; spadices 

 simple or fastigiately branched, pendulous, 

 floriferous branchlets catkin -like, rather 

 short, remote or clustered, sessile or pendu- 

 lous: fls. polygamous-dioecious, usually rose- 

 colored: fr. globose, turbinate or ovoid, 1-3- 

 seeded, usually beaked. About 14 species, 

 Assam and Malay. Two forms have been 

 sometimes cult. Z. edulis, Blume (Z. Blume- 

 d,na, Mart.). Lvs. copious, clustered, erect, 

 clothed with long, often serrate prickles; 

 pinnae linear-lanceolate, very long-acumi- 

 nate, \YT-^A ft. long, l^r-2 in. broad, 

 whitish beneath; petiole rather shorter than 

 the rachis and armed with robust prickles: 

 spadices drooping, long-branched: fr. ful- 

 vous-fuscescent, pyriform, 2}^ in. long. 

 Malay Archipelago. Var. Wallichidna, Mart. 

 (Z. Wallichiana, Mart.), has Ivs. 18-20 ft. 

 long, clustered, nearly erect; pinnse fascicled 

 in 2's, 3's, or 4s, narrow-lanceolate, with a 

 long and slender, cuspidate point, atten- 

 uated and reduplicate at base, flat, older 

 ones 1>2 ft. long, 3-4 in. broad; petiole 

 4-6 ft. long, armed with robust, fuscous 

 prickles: fr. ovate-pyriform, 1J^ ft. long. 

 India, Burma, and Malaya. G.C. 1873 : 1083.

ZALUZANIA (named for the Pole, Adam 

 Zaluziansky von Zaluzian). Compdsitse. 

 Hoary -tomentose or scabrous - pubescent 

 shrubs or subshrubs: Ivs. alternate, entire, 

 dentate, lobed or many-cut: heads pedi- 

 celled, heterogamous, arranged in corymbose 

 leafy panicles: ray-fls. in 1 row, pistillate; 

 disk-fls. perfect and fertile ; involucre broadly 

 campanulate; corolla yellow or perhaps 

 white. About 12 species, Mex. Apparently 

 none in cult. 



ZALUZIANSKYA (after Zaluziansky, a3 

 indicated above, who wrote Methodus Her- 

 barise, Prague, 1592). Including Nycterinia. Scrophula- 

 riacese. More or less viscous annual or perennial garden 

 herbs, also grown in the greenhouse. 



Leaves, lowest opposite, upper alternate, usually few- 

 toothed; floral Ivs. smaller, bract-like, entire: fls. sessile, 

 usually arranged in dense or interrupted terminal spikes; 

 calyx ovate-tubular, shortly 5-toothed, 2-lipped or 2- 

 parted; corolla persistent, tube elongated, finally split to 

 the base; limb 5-lobed, entire or 2-cleft; stamens usually 

 4: caps, oblong, leathery or membranaceous, septicidally 

 dehiscent. About 36 species, natives of S. Afr. All the 

 species mentioned here have then- corolla lobes bifid.

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 unsatisfac- 

 tory and urge that the seed be sown in the 

 autumn and the young plants wintered in 

 a coldframe. They will then begin to flower 

 by June. The blossoms are closed by day 

 and are fragrant by night. 



A. Corolla-tube slightly pubescent. 

 B. Duration perennial: bracts broadly lanceo- 

 late: Ivs. oblong-linear. 

 lychnidea, Walp. (Nycterinia lychnidea, 

 D. Don. Ennus lychnidea, Linn. E. grdcilis, 

 Lehm., not Hort.). Subshrub, about 2 ft. 

 high: Ivs. oblong-linear, sessile, entire or 

 few-toothed: corolla-tube 1-1 J^ in. long, 

 limb M~%in. across, white inside, purplish 

 or red outside. B.M. 2504; 8215 (the latter 

 asZ.maritima'). B.R.748. G.C. III. 42:162 

 (as Z. maritima). Usually acts much like 

 an annual and is generally treated as such 

 when cult. 



BB. Duration annual: bracts oblong-lanceo- 

 late: Ivs. linear or the lower ones lanceolate. 

 capensis, Walp. (Nycterinia capensis, 

 Benth.). Differs from the above, as de- 

 scribed by Bentham, in stature, duration, 

 strict sts. and smaller Ivs., but unfortunately 

 Bentham does not give the height of the 

 plant or color of the fls. According to R.H. 

 1851 : 221, the plant has white or lilac fl.-clus- 

 ters on the same plant, each fl. having an 

 orange eye. The spikes, according to Ben- 

 tham, are commonly short and 4-8-fld., some- 

 times long and 15-20-fld. There is some evi- 

 dence that this species and the next are con- 

 fused in the trade. In R.H. 1851 : 221 the fls. 

 are %-l in. long and less than J^in. across. 



AA. Corolla-tube glabrous. 

 selaginoides, Walp. (Nycterinia selaginol- 

 des, Benth.). Dwarf annual, branched at the 

 base, 3-5 in. high, rarely 6 in., with spatulate 

 Ivs. and fls. 1 in. long, color of fls. not 

 Stated by Bentham, but in R.H. 1896, p. 308 

 (same picture as Gn. 24, p. 89) the fls. are said 

 to range from white to lilac and darker depending on 

 their stage of development, with an orange-colored eye 

 which becomes crimson later. This suggests the preced- 

 ing species, and it is evident that the two must be dis- 

 tinguished by technical characters until the colors can 

 be verified. G.C. III. 55:173. The plant once adver- 

 tised in America as Nycterinia selaginoides is said to be a 

 pink-fid, half-hardy perennial, growing 9 in. high, which 

 does not agree with authentic descriptions. A species 

 passing under this name is hardy at San Francisco.
