Acidanthera— continued. 
much on the lines of Ixias, which it approaches. It 
makes a very good pot-plant. 
A. equinoctialis eee jl. about six in a distichous 
ike ; perianth-tube Sin. to 6in. long, the limb 2in. in diameter, 
the segments white, with an acute, purple spot at base; outer 
spathe-valves 3in. to 4in. long. November. J. ae super- 
posed, ensiform, lft. to 14ft. long, strongly ribbed. Stem 
stiffy erect, 3ft. to 4ft. high. Corm large, depressed-globose. 
Sierra Leone, 1893. This requires a warm house. (B. M. 7395.) 
A. bicolor (two-coloured). /l. few, in a very lax spike ; peri- 
anth white, with a slender tube 4in. to Sin. long, the segments 
acute, liin. to ljin. long, the three lower ones conspicuously 
spotted with purple at the throat. Stem simple. Corm 
lobose, sin. in diameter. Abyssinia, 1896. Hardy. (G. C. 
fi , XX., p. 393.) 
A. capensis (Cape). The correct name of Tritonia capensis. 
ACINETA. Sxn. Neippergia. This genus comprises 
about eight species, all natives of tropical America. 
Though classed as cold-growing Orchids, the Acinetas 
thrive more satisfactorily in an intermediate tempera- 
ture, especially during the dull winter months of the 
year. They require a liberal amount of moisture at 
the root during the growing season, but care must be 
taken to avoid stagnation, which causes the potting 
compost to decay, whereby the roots and the general 
health of the plant are affected, often leading to’ de- 
struction. Syringing and damping overhead must also 
be done with discretion, and should only be attempted in 
bright, dry weather. It should always be done sufli- 
ciently early in the day to enable the foliage to become 
dry again before the evening, when a fall of tempera- 
ture sets in. Excessive agcumulation of moisture in the 
hearts of the young growths must also be strictly guarded 
against, or they will quickly rot off. Where accumu- 
lated moisture is observed, the plant should be held 
upside down, and by gently tapping the growth affected 
the moisture will be dispersed. These precautions are 
especially necessary when the plants are grown under 
cool conditions, or suspended in a house where the sash- 
bars are not properly grooved to carry off the condensed 
moisture. Propagation is effected by division of the 
pseudo bulbs, preferably when the new roots are emitted 
from the base of the newly made growths. Purchase of 
Imported plants is, however, by far the most satisfactory 
way of increasing the stock. To the species described 
on p. 14, Vol. I., the following should be added: 
A. Hrubyana (Hruby’s). #7. ivory-white, disposed in loose 
racemes; lip marked with a few purple spots, and having 
narrow, erect side lobes. Colombia, 1852. A fine and distinct 
‘ies. 
spec 
A. Humboldtii fulva (fulyous). /l. tawny-yellow, dotted all 
over with ep ae ; lip of a brighter yellow, spotted with 
dark purple. A handsome variety. (B. M. 4156.) 
A. H. straminea (straw-coloured). 7. pale straw-yellow, with 
very few spots. Colombia. 
A. superba (superb). A synonym of A. Humboldtii. 
A. Wrightii (Wright's). A synonym of Lacena spectabilis, 
ACINOS. Included under Calamintha (which see). 
ACIOTIS. Syn. Spennera. About twenty-six species 
of this genus, natives of the West Indies and tropical 
America, have been described. 
ACIPHYLLA. Syn. Gingidiwm (of F. Mueller). 
This genus includes about a score of species, natives of 
New Zealand and Australia. To those described on p. 14, 
Vol. I. (both of which are called “ Wild Spaniard” by 
settlers), the following should be added: 
A. hoa (Lyall’s). fl. white; inflorescence long and con- 
tracted; female umbels almost concealed in the tumid sheaths 
of the bracts; male umbels on spreading, branched peduncles. 
1. simply pinnate or trifoliolate; leaflets rigid, pungent, 4in. to 
6in. long, tin. broad. New Zealand, 1889. 
ACIS. This genus is included by J. G. Baker under 
Leucoium (which see), the specific names remaining 
unchanged. A. grandiflorus is, however, regarded as 
merely a variety of A. (Leucoiwm) trichophyllus. 
A. roseus longifolius (long-leaved). This differs from the 
t in its larger flowers, longer leaves, and more ‘lorif. 
habit. Corsica’ 1886. : : fr earet

ACISANTHERA. Syn. Uranthera. According to 
the “Genera Plantarum,” this genus embraces about 
fourteen species of glabrous, pilose, or slightly hispid, stove 
herbs (often annuals) or sub-shrubs, inhabiting the West 
Indies and tropical South America. Flowers purple and 
pink, terminal and axillary, shortly paniculate; calyx with 
a hemispherical or campanulate tube and four or five 
acuminate lobes as long as the tube; petals four or five, 
obovate or orbicular; stamens eight to ten, unequal. 
Leaves almost sessile, entire or serrated. A. quadrata is 
probably the only species in cultivation. 
ACMELLA. Included under Spilanthes (which see). 
ACMENA. Bentham and Hooker include this genus 
under Eugenia. 
A. floribunda. Synonymous with the plant correctly described 
in Vol. I. as Eugenia Smithii. (B. M. 5480.) 
ACOKANTHERA. This is the correct name of 
the genus described on p. 63, Vol. IV., as Toxicophlea 
(which see). 
ACONITUM. According to Bentham and Hooker, the 
number of distinct species is only about eighteen, many of 
the plants described on pp. 15-17, Vol. I., being mere 
varieties. They are chiefly mountain plants, spread over 
the greater part of Europe and Central Asia, very few 
species being found in North America. A. Napellus is a 
British species. 
Though Aconites will grow fairly well almost 
anywhere, they are best accommodated in a deep, 
fairly rich soil, and in partial shade. Their spikes of 
flowers look remarkably well in a mixed border of good 
width. They are best divided in autumn. The following 
are the only additions calling for mention : 
Sect. I.—_Roots Tuberous. 
A. californicum (Californian). A garden synonym of A. 
cherr. 
A. decorum (neat). A garden synonym of A. Cammarwm 
A. dissectum (dissected). This plant has much in common with 
A. Napellus, but it is more hatry. The principal difference is 
exhibited in the narrower helmet of the flowers. Himalayas,

A. Fischeri (Fischer's). jl. pale blue, large, puberulous, many in 
a straight, erect raceme. October. /., cauline ones petiolate, 
tripartite; segments cuneate, trifid, incised-lobed. Europe, 
North America, &c., 1886. Plant erect, robust. (B. M. 7150.)

ACRATHERUM. A synonym of Arundinella

ACRIDOCARPUS. Sxn. Anomalopteris. This 
genus embraces about a dozen species of stove or green- 
house trees and shrubs, natives of tropical and South 
Africa, Madagascar, and Arabia. Flowers yellow, racemose 
or rarely corymbose; calyx deeply five-cleft; petals 
unequal, clawed, almost entire; stamens ten, all perfect ; 
racemes or corymbs terminal and lateral, often paniculate. 
Leaves alternate, rarely opposite, entire, often glandular 
beneath, without stipules. 
ACROCHZENE (probably from akros, top, and chaino, 
to gape; reason not obvious). Orv. Orchider. A 
small genus (two species) of stove, epiphytal Orchids, 
natives of tropical Asia. Sepals spreading, sub-equal ; 
petals small, lacerated; lip erect, shorter than the sepals, 
with a short claw; scape lateral, erect; raceme long, lax.
