ZISCULUS. Syn. Hippocastanum. This genus in- 
cludes about fourteen species of trees and shrubs, natives 
of North America and the mountains of Colombia,

panicles; calyx campanulate or tubular, five-cleft; petals 
four or five, unequal, clawed, imbricated; stamens five to 
eight, free. Capsules coriaceous, smooth or prickly, three- 
lobed or sub-globose, three-celled, or by abortion one- or 
two-celled. Leaves opposite, without stipules, digitately 
five- to nine-foliolate; leaflets serrated. To the species 
described on p. 34, Vol. I., the following should be added.

This tree closely resembles 42. Hippocastanum in general appear- 
ance, but is readily distinguishable by its leaves being of a pale 
greyish colour beneath. SYN. 42. chinensis, of gardens. 
2G, Watsoniana (Watson's). A form of 4. rubicunda. 
JETHEILEMA. A synonym of Phaylopsis (which 
see). 
ZETHIONEMA. About sixteen species, natives of the 
mountains of Southern Europe, Asia Minor, and Persia, are 
included in this genus. Flowers pink or purple, small, 
without bracts, on slender pedicels. 
There is no better subject for the rock-garden than 
ZE. grandiflorwm, once it is established. It is, however, a 
true sun-lover, and if a little lime be mixed with the 
soil in the particular nooks in which it is grown, a fine 
mass of pink blossom will be produced in summer. Its 
prostrate habit lends itself well to rockery decoration. 
ZETHONIA. Included under Tolpis (which see).

AFZELIA. This genus embraces about ten species 
of unarmed, stove trees, natives of tropical Africa and 
Asia. Flowers rather large, racemose; calyx segments 
four, imbricated ; petal clawed, orbicular or reniform, 
the lower rudimentary ones small or wanting; stamens 
three to eight, free; racemes crowded in panicles at the 
tips of the branches. Pods obliquely oblong, compressed. 
Leaves abruptly pinnate or rarely almost imparipinnate ; 
leaflets in few pairs, coriaceous. A. africana is the best- 
known species.

AGALMYLA. Syn. Orithalia. This is a monotypic 
genus, A. longistyla being merely a long-styled form of 
the true species, A. staminea. 
AGANISIA. Syn. Koellensteinia. The half-dozen 
species of this genus are confined to tropical America. To 
those described on p. 35, Vol. I., the following should be 
added : 
A. czrulea. The correct name is Acacallis cyanea. 
A. cyanea (blue). fl. rather small, in a short, erect raceme; 
sepals and petals white, ovate, acute ; lip blue, roundish-cuneate,

A. tricolor (three-coloured). jl. closely resembling those of 
A. cyanea, but the sepals are whitish on both sides, the petals 
are light blue, and the callus of the saddle-shaped, pe ee 
lip is different in shape. Amazons, 1886. A fine Orchid. 
AGANOSMA. This is regarded by Bentham and 
Hooker as synonymous with Ichnocarpus (which see). 
AGAPANTHUS. Syns. Abumon, Mauhlia. Ac- 
cording to Baker (‘Flora Capensis,”’ vol. iii.) this genus 
is monotypic. To the varieties described on p. 36, Vol. L., 
the following should be added: 
A. umbellatus atroczruleus (dark blue). /. of a beautiful 
dark violet. 
A. u. giganteus (etponte) A very robust form, with a very

AGAPETES. This genus includes about twenty-five 
species, natives of India, the Malayan Peninsula, and Fiji. 
To those described on p. 36, Vol. I., the following should 
be added :

corolla 1gin. long, 4in. to Zin. broad. December. 7. shortly 
petiolate, lanceolate, narrowed at both ends. Khasia, Moul- 
mein, &c., 1849. This closely resembles A. variegata, but has 
much larger flowers. SyN. Thibaudia macrantha (B. M. 4566). 
A. Mannii (Mann’s). jf. white, in. long, with a cylindrical 
corolla. 2. lanceolate. Branches almost glabrous. Otherwise 
like A. obovata. Northern India, 1892. Greenhouse. 
A. obovata (obovate). jl. reddish-brown, solitary, about 4in.

aceous, obovate, about sin. long. Branchlets scurfy and thickly 
leafy. Northern India, 1892. A dwarf, densely-branched, not 
very ornamental, greenhouse shrub. 
A. 1 eet (very pretty). A synonym of A. variegata, with 
which Thibaudia pulcherrima (B. M. 4303) and 7. varieyata are 
also identical. 
AGARICUS. To this genus belong several very 
destructive and common fungi met with upon various 
conifers and other subjects, as well as upon orchard trees. 
The best known is A. melleus (Armillaria mellea), or 
Honey Agaric, an edible fungus found in late summer upon 
trees of many kinds, but particularly upon Spruce, Pines, 
Larch, Beech, and less often upon Plum. This species, 
fully dealt with under Pine Fungi, is responsible for 
the condition known as Tree-Root Rot. Not so well 
known as the Honey Agaric is A. adiposus (Pholiota 
adiposa), a species with bright yellow slimy cap, covered 
with reddish-brown scales; the gills are yellow, changing 
to reddish-yellow, and the reddish pileus scales extend 
on to the stem. Like A. melleus, it grows in clusters; 
but, unlike that species, it is not edible. This is found 
much later than A. melleus, and on both living and dead
