1900 SUPPLEMENT—RECENT INTRODUCTIONS, 
ey. Lay 
AVERRHOA. Only the two species described are 
included in this genus. They are indigenous in tropical 
Asia. Flowers small, cymulose, regular; sepals five, 
imbricated ; petals five, hypogynons, twisted ; stamens ten ; 
eymes in short panicles. Leaves alternate, impari- 
pinnate, exstipulate. A. Bilimbi is known as the Cucumber- 
tree. 
AVERRUNCATOR. This useful implement is better 
lkmown as the Standard Tree Pruner, and is in use 
in most gardens where tall trees have to be pruned. 
Probably the best is that made by the Standard Tree 
Pruner Co., Derby, as it is easy to work and handle, 
making clean cuts. It is made in various sizes, and 
considerably economises labour. 
AVICENNIA (named in honour of Avicenne, a 
celebrated Arabian philosopher and physician, 980-1037). 
Syns. Bontia (of Linneus), Donatia, Halodendron (of 
Thouars), Scewra, Upata. Orv. Verbenacew. A small 
genus (three or four species) of glabrous or canescent, stove 
shrubs, broadly dispersed over the sea-shores of the warmer 
parts of the globe. Flowers small, sessile, in contracted, 
head-like, pedunculate cymes; calyx five-parted; corolla 
limb five-cleft ; stamens four; bracts shorter than the 
calyx. Leaves opposite, entire, coriaceous. A. nicida and 
A. officinalis are occasionally grown in Continental gardens, 
but they have little decorative value. 
AWN. A bristle-like appendage; e.g., those on the 
glumes of many of the Grasses. ; 
AXE-WEED. Sce Securigera Coronilla. 
AYENTIA (named in honour of the Duke d’Ayen). 
Syn. Cybiostigma. -Orp. Slerculiacer. A genus com- 
prising eight species of stove herbs or sub-shrubs, natives 
of the warmer parts of America. Flowers small, 
pedicellate, fascicled or cymose; calyx five-parted ; petals 
five. Leaves serrated. A. levigata and A. pusilla have 
been introduced, but are probably no longer in culti- 
vation. 
AYRSHIRE ROSE. See Rosa repens hybrida. 
AZALEA. This genus is now included by the best 
authorities under Rhododendron. 
Thrips, Red Spider, and most of the other animal 
pests to which Azaleas are liable are now best got rid 
of by means of the XL All Vaporiser. This may be 
used without the least injury to the tender foliage. More 
_ troublesome to the cultivation of Azaleas indoors is, how- 
ever, bud-dropping, which usually follows if the plants 
do not receive a sufficiency of moisture at the roots. 
To the species, varieties, and hybrids described on 
pp. 149-50, Vol. I., the following should be added: 
A. balsamineefiora alba (white). 1. white, produced in large, 
compact trusses, and lasting a long time in perfection. 
A. b. aurea (golden). A form differing from alba in its bright 
yellow flowers. : 
A. b. carnea (flesh-coloured). l. flesh-coloured, tinted with rose, 
and also with pale yellow when first expanded. 1887. 
The preceding are garden hybrids raised from a Javanese 
species. 
A. dianthifiora (Dianthus-flowered). fl. of a rose or violet 
colour, dotted with brown, sweet-scented ; calyx lobes long, 
pubescent ; corolla din. in diameter; pedicels tomentose. May 
and June. 7. rather large, elliptic-oblong, softly hairy. Japan, 
1889. A vigorous, free-flowering, hardy shrub. 
A. hybrida Daviesii (Davies’ hybrid). jl. white. 1893. A garden 
hybrid, supposed to have originated by crossing A. sinensis with 
A, viscosa. (R. G. 1387.) 
A. nitida (shining). A form of A. viscosa. 
A. obtusa (blunt). #7. deep red, solitary ; segments of the corolla 
nearly oval and sharp-pointed, the upper one not much smaller 
than the others, and faintly blotched purple. March. J. pilose, 
oblong, obtuse, narrowed at base. h. 2ft. China, 1844. Green- 
house evergreen. (B. R. xxxii. 37; G. C. n. s., xxv., p. 585.) 
A. o. alba (white). A variety differing from the type only in the 
colour of its flowers, which are white, occasionally striped red. 
1887 
A. occidentalis (Western). . rather unpleasantly scented, 
produced when the leaves are almost fully developed ; corolla 
Azalea— continued. 
white or rarely having a slight rosy tinge and a pale yellow 
band on the upper lobe, often 2sin. long. 7. obovate-oblong, 
lin. to din. long, nearly glabrous at maturity, but ciliated, 
thickish. h. 2ft. to 6ft. California. 
A. rhombica (rhomboid-leayed). qe usually in pairs; calyx 
minute; corolla bright rose, Ijin. fo 2in. across, sub-bilabiate. 
May, ¢. sub-conical, lin. to 2in. long, assuming a bronzy 
hue in autumn, the young ones silky, rhombic-elliptic, acute at 
both ends, hairy above, finely reticulated beneath. Branches 
slender, stiff, glabrous, the young ones _strigose-tomentose. 
Japan. A much-branched, hardy shrub, SYN. Rhododendron | 
rhombicum (B. M. 6972). 
A. rustica (rustic). This name has been applied to a garden 
race, said to be derived from A. sinensis (mollis) and A. occi- 
dentalis. 1893. :
