Zygostates
(from zygos, a yoke, and statos, standing; alluding to the two processes which stand out horizontally from the base of the column, and together somewhat resemble a yoke). SYN. Dactylostyles. ORD. Orchideae. A small genus (three or four species) of dwarf, epiphytal, stove Orchids, found in Brazil. Flowers small, racemose, on axillary peduncles; sepals sub-equal, free, spreading or reflexed; petals similar or broader; lip continuous with the base of the column, spreading, concave, undivided, with an incurved appendage at base; column arched, semi-terete. Leaves fleshy or coriaceous; sheaths scarcely thickened into pseudo-bulbs. Only one species has been introduced. For culture, see Burlingtonia.
Z. Greeniana (Green's). fl., sepals oblong, obtuse; petals white, ovate, foothleted; lip white, streaked with green, foveate, rounded; peduncles short, two-flowered. l. cuneate-ligulate, trigonal, fleshy, superposed. Pseudo-bulbs minute, somewhat pear-shaped, one-leaved. 1869. A curious little plant. NEW INTRODUCTIONS, ETC.
THIS Appendix contains all the new plants of any horticultural interest which have been introduced to British gardens during the progress of the publication of the DICTIONARY OF GARDENING, as well as some older ones--worthy of being included--which have been omitted under their respective genera. ABELIA. This genus embraces about half-a-dozen species, natives of the Western Himalayas, China, Japan, and Mexico. To those described on p. 1, Vol. I., the following should now be added:
A. rupestris grandiflora (large-flowered). fl. rosy-white, larger than those of the type. Whole plant more robust. A seedling of Italian origin. A. spathulata (spathulate). fl. sessile, in pairs on a short, slender peduncle; corolla white, with yellow blotches on the throat, nearly 1in. long. April. l. about 2in. long, elliptic-lanceolate, obtusely acuminate, sinuate-toothed, glabrous above, pubescent beneath, edged purple. Japan, 1883. A free-flowering, much branched, evergreen shrub. (B. M. 6601.) ABIES. To the species described on pp. 1-2, Vol. I., the following should now be added:
A. Eichleri (Eichler's). This is closely allied to A. Nordmanniana, from which it may be distinguished by its cones, which in a young state are bluish-black instead of green, and at a corresponding stage are 2 4/6in. long and 1in. broad, by the whiter or paler under surface of its mature leaves, and by the blue-green colour of its young shoots. Caucasus. (W. G. Z. 1882, No. 2.) A. Nordmanniana (Nordmann's). l. on the sterile branchlets either two-ranked or arranged more or less round the branches, linear, flat, retuse at apex, green above and scarcely sulcate, below one-ribbed, with two white lines; those on the fruiting branches curved, ascending or erect. cones sessile, elliptic-oblong or cylindrical; bracts cuspidate, exserted, reflexed; scales reniform from a shortly cuneate base. Branches horizontally whorled, the lower ones deflexed. Asia Minor. A tall tree, of pyramidal habit. (B. M. 6992 R. G. 699.) A. N. horizontalis (horizontal). A dwarf, compact-growing form, with horizontally spreading branches; it cannot be made to produce a leader, hence its peculiar habit. A chance seedling found in a nursery in the Vosges. ABROMA. The two or three species embraced in this genus inhabit tropical Asia and Australia. To those described on p. 3, Vol. I., the following should now be added:
A. sinuosa (sinuate). l. broadly ovate, pedately pinnatifid, on slender petioles. Madagascar, 1884. A pleasing species, of slender habit. ABUTILON. A genus of about seventy species, distributed over the warmer regions of the globe. To the species and varieties described on pp. 4-5, Vol. I., the following should now be added:
A. Thompsoni flore-pleno (double-flowered). A garden variety with double flowers. 1885. Greenhouse. (R. H. 1885, p. 324.) Varieties. CHRYSOSTEPHANUM COMPACTUM, a pleasing shade of chrome-yellow; a good variety for bedding out. MADAME JOHN LAING, rose, very large flowers. M. H. CANNELL, a very free-flowering hybrid from A. megapotamicum. ACACIA. Leaves bipinnate; leaflets often small and many-jugate, or reduced to a filiform petiole (phyllode). To the species described on pp. 5-7, Vol. I., the following should now be added:
A. leprosa (leprous). fl. numerous in a globular head, mostly five-parted; petals yellow, united to the middle. May. l., phyllodia narrow, linear-lanceolate, acute, or obtuse with a small point, narrowed at base, 1 1/2in. to 3in. long. Branchlets pendulous, more or less glutinous. Australia, 1817. A tall shrub or small tree. (B. R. 1441.) A. lineata (lined). fl. ten to fifteen or more in a small, globular head, mostly five-parted; petals yellow, smooth. April. l., phyllodia linear, with a small, hooked point, usually 1/2in. to 3/4in. long. Branches pubescent or villous, sometimes slightly resinous. h. 6ft. Australia, 1824. (B. M. 3346.)
