1780-1856, a Swedish botanist). Ord. Thymeleacee. 
A genus comprising about twenty species of stove or 
greenhouse shrubs or trees, natives of tropical and 
Eastern Asia, Australia, and the Pacific Islands 
Flowers shortly racemose or spicate at the tips of the 
branches; perianth having an elongated tube and four 
spreading lobes; stamens eight, included or shortly 
exserted. Leaves opposite or rarely alternate. W. 
Alberti is a greenhouse, deciduous, much-branched shrub, 
requiring similar culture to Thymelza (which see, on 
p. 35). W. viridiflora—the bark of which yields a valuable 
paper material—is also in cultivation in botanical gardens. 
None of the species, however, are of any horticultural 
value. 
W. Alberti (Albert's). fl. golden, capitate-umbellate ; umbels 
pedunculate at the tips of the branches and _ branchlets. 
1. scattered or rarely nearly opposite, obversely lanceolate, or 
very rarely the uppermost ones linear-oblong, }in. to 14in, long, 
penninerved, rounded or rarely somewhat acute at apex. 
Branches glabrous, terete. h. 1ft. to 2ft. Bokhara, 1887. (R. G. 
1262, under name of Stellera Alberti.)

ZYGOCOLAX (a word made up from the generic 
names of the parent plants). Orp. Orchidew. A name 
applied to a hybrid obtained by crossing Colax jugosus 
(male) and Zygopetalum crinitwm (female), between which 
it is almost intermediate in shape. For culture, see 
Zygopetalum, on p. 245. 
Z. Veitchii (Veitch’s). ”. handsome, 2in. across; sepals and 
petals light greenish-yellow, blotched purple-brown ; lip 
yellowish-white, longitudinally striated with violet-purple ; 
seape a little shorter than the leaves, with a few sheathing, 
lanceolate, acute bracts. J. two or three, linear-lanceolate, 9in. 
to 12in. long, the basal ones a little broader and shorter than the 
upper ones. 1887. 
ZYGOPETALUM. To the species described on 
pp. 245-8, the following should now be added: 
Z. Crepauxi (Crepaux’s). /l. showy, rather crowded ; sepals and 
petals dark red, spotted and striped yellow ; lip large, white, 
with violet lines on the margin, the nerves covered with short, 
violet-rose hairs. Jl. shortly stalked, elliptic-obovate. Pseudo- 
bulbs small, angular. Brazil, 1887. A robust, tufted, stove 
species. 
Z. Ruckerianum (Rucker’s). /., sepals and petals white, with 
a Jarge, light purple area near the green base, twisting, undu- 
lated, acute ; lip purple, with a white callus and some yellow at 
the base of the side lobes, revolute on each side, and rolled 
underneath at the top. 1885. Stove. Much in the way of 
Z. Dayanum. 
Z. Wallisii (Wallis’). The correct name of the plant described on 
p. 161, Vol. L., as Batemannia Wallisii.
