wood. Firs, again, are the principal host-plants, and the 
wood of stems so attacked breaks up in a remarkable 
manner as the fungus spreads, and usually takes on an 
unhealthy, yellowish-brown colour. Trees subject to canker 
are frequently attacked by this species, whose sporospores 
may be found growing out of the wounds caused by the 
eanker-fungus. Besides being of a bright yellow, the cap, 
as wellas the stem, is covered with darkish scales. See 
Pine Fungi and Honey Agaric for remedies. 
AGARISTA (a name of mythological origin, after 
the beautiful daughter of Clisthenes; in allusion to the 
beauty of the flowers). Syn. Amechania. Orv. Ericacex. 
A genus embracing about twenty-two species of green- 
house, glabrous or pubescent, usually evergreen shrubs, 
natives of Brazil, New Granada, Peru, and Mexico. 
Flowers white, pink, red, or purple, in axillary and terminal 
racemes; calyx free, five-lobed or parted; corolla conico- 
tubular or urceolate, with five recurved teeth ; stamens ten, 
included; filaments shortly adherent. Leaves alternate, 
hard, coriaceous, reticulate-veined. The two species here 
described thrive in a compost of peat and sand. Cuttings, 
not too young, will strike in sand, under a hand-glass, in 
moderate heat. See also Agauria. 
A. neriifolia (Nerium-leaved). (fl. crimson, urceolate, tubular, 
secund, drooping, disposed in a terminal, racemose panicle. 
June. 2. petiolate, oblong-lanceolate, acute, 3in. long, lin. 
broad, ovate at base, coriaceous, entire, pale beneath. kh. 2ft. 
Brazil, 1849. Plant highly glabrous. Syns. Andromeda 
neriifolia, Leucothoe neriifolia (B. M. 4593).

Syns. Andromeda pulchra, Leucothoe puichra (B. M. 4314). 
AGARISTA (of De Candolle). Included under 
Coreopsis (which see). é 
AGATHZEA. Blue Marguerite; Cape Aster. Bentham 
and Hooker refer this genus to Felicia, but the correct 
name of A. celestis is Aster rotundifolius. 
A. amelloides (Amellus-like). A synonym of A. celestis (rotundi- 
Solius). 
AGATHELPIS (from agathos, pleasant, and thelpis, 
hope ; reason for name not obvious). Orp. Selaginee. A 
small genus (less than half-a-dozen species) of greenhouse 
shrubs or under-shrubs, natives of South Africa. Calyx 
limb shortly five-cleft ; corolla spreading, star-like ; stamens 
two, affixed above the middle of the tube; spikes usually 
slender, elongated. Leaves scattered, linear or small. 
A. angustifolia and A. parvifolia have been introduced, but 
it is doubtful if they are still in cultivation. , 
AGATHIS. According to the authors of the “ Genera 
Plantarum,” this is the correct name of Dammara 
(which see). 
AGATHOMERIS. A synonym of Humea (which 
see). 
AGATHOPHYLLUM. This is now regarded as a 
synonym of Ravensara (which see). 
AGATHOSMA. As many as a hundred species are 
included in this large genus. 
A. acuminata is a variety of A. imbricata. 
A. bruniades is a variety of A. cuspidata (the type is not in 
cultivation). 
A. villosa (villous). #. flesh-coloured, lilac, or white. h. 1ft. or 
more. This is probably identical with Diosma Wendlandi. 
AGATHOTES. A synonym of Swertia (which see). 
AGATI. This is now included, by Bentham and 
Hooker, under Sesbania, A. coccinea being regarded as a 
form of S. grandiflora (which see). 
AGAURIA (name not explained by author). Syws. 
Agarista and Leucothoe (in part). Orp. Ericacew. A 
small genus (four species) of greenhouse, evergreen, highly 
glabrous or glandular-pubescent shrubs or small trees, 
natives of tropical Africa, Madagascar, and Mauritius. 
Flowers generally white, in axillary and terminal racemes ; 
Agauria—continued. 
calyx free, five- or six-cleft or parted; corolla cylindrical 
with five recurved teeth ; stamens ten to twelve, included. 
Leaves almost opposite and alternate, oblong or lanceolate, 
entire, pale beneath. For culture of the two species 
described, see Andromeda. 
A. buxifolia (Box-leaved). 7. pink, in terminal racemes ; pedicels 
somewhat secund. Summer. J. very shortly petiolate, cori- 
aceous, highly glabrous, broadly ovate or nearly oblong, mucro- 
nate, somewhat cordate at base, glaucous and at leneth almost 
ferruginous beneath. h. lft. Mauritius, 1822. Greenhouse. 
Syn. Andromeda buaxifolia (B. M. 2660; L. B. C. 1494).

vation) whitish ; corolla oval-oblong ; pedicels spreading-recurved, 
somewhat secund. June. J. petiolate, narrow-lanceolate, acumi- 
nate at both ends, entire, green above, woolly beneath. h. 4ft. 
Mauritius, 1825. Hardy. SyN. Andromeda salicijolia (B. M. 
3286; H. E. F. iii., t. 192). 
AGAVE. Including Littwa. According to J. G. 
Baker’s monograph of the Amaryllidex, this genus em- 
braces nearly 140 species, natives of tropical America, 
and especially plentiful in the Southern United States. 
Flowers greenish-yellow ; perianth tube short, the segments 
almost equal, oblanceolate, faleate; stamens inserted at or 
below the throat of the tube; filaments filiform, usually 
much longer than the segments; inflorescence densely 
sub-spicate or a thyrsoid panicle; peduncle having only 
reduced leaves. Fruit an oblong capsule, loculidally 
three-valved. Leaves densely rosulate, more or less 
fleshy and usually firm in texture, with a pungent spine 
at the tip and numerous horny prickles on the margins. 
The great majority of Agaves are monocarpic, i.e., only 
fruiting once. Several polycarpic species have been noted 
at Kew, and itis worthy of mention that all these belong 
to the sub-genus Litiza, in which the flowers are borne in 
pairs, forming a dense sub-spicate inflorescence. So far as 
is known at present, none of the sub-genus Euagave, of 
which the common A. americana may be taken as the 
type, are polycarpic, but die after flowering. 
To the species and varieties described on pp. 38-42, 
Vol. I., the following should be added:
