DIACALPE (from dia, through, and calpis, an urn; 
referring to the disposition of the spore-cases). ORD. 
Filices. A monotypic genus. Inyolucre inferior, globose, 
hard-membranaceous, entire, at length bursting very 
irregularly at the summit. Capsules numerous, nearly 
sessile. Sori globose; the receptacle small, scarcely ele- 
vated. For culture, see Ferns. 
D. aspidioides (Aspidium-like). Jronds tripinnate, sub-mem- 
branaceous, often deciduously crinite ; E oblong-cuneate, 
lobed, more or less decurrent. Malay Islands, &c. Stove. 
DIADELPHOUS. Applied to the stamens when they 
are connected into two bundles. © 
DIANDROUS. Having two stamens. 
DIANELLA (a diminutive of Diana, the sylvan 
goddess; in reference to the plants growing in woods). 
Syn. Rhuacophila. Orv. Liliacem. Very ornamental 
fibrous-rooted half-hardy perennials. Flowers paniculate, 
on drooping pedicels; perianth six-cleft. Leaves grass-like. 
The species thrive, in sheltered spots in the southern coun- 
ties, in a mixture of loam and peat. All succeed well 
planted out in the cool conservatory. Increased readily 
by divisions; or by seeds, sown in gentle heat, in spring. 
D. ezerulea (sky-blue) Л. blue ; branches of panicle short. May. 
l., stem ones long, numerous, ensiform, rough at the edge and 
keel. A.2ft. New South Wales. (B. M. 505.) 
D. intermedia (intermediate) fl. whitish, numerous, disposed in 
much-branched panicles 10in. to 18in. long. J. linear, ensiform. 
New Zealand. A free-growing species, producing bunches of 
pretty dark blue berries. 
D. levis (smooth).* /l. bluish, in loose racemes ; pedicels filiform, 
solitary, upright, distant, erecto-patent, scattered; corolla re- 
flexed, inner segments ruled down the middle with three deeply- 
coloured lines, parallel with the axis of the segment ; outer with 
five similar ones; filaments bent at the to , and connected by 
a joint with a short, thick, orange-coloured, irregularl oblong 
strumous y, on the inwardly shelving summit of which the 
anther is fixed by its base. Spring. l. bright green, ensiform, 
broad, smooth, and keeled. h. 2ft. New South Wales, 1822. 
SYN. D. strumosa. (B. R. 751.) 
D. strumosa (strumous) A synonym of D. levis. 
D. tasmanica (Tasmanian)* /l. pale blue, drooping, 2in. to 2in. 
in diameter ; D large, loose, decompoundly branched, very 
many-flowered ; perianth —— oblong, reflexed. Berries 
deep blue, jin. to Zin. long, broadly oblong. J. 3ft. to 4ft. long, 
broadly ensiform, with revolute margins, armed with spinular 
teeth. Tasmania, 1866, A very ornamental, large, rigid, grassy- 
leaved plant, sometimes attaining a height of 5ft. It forms а 
conspicuous ornament for the conservatory, its chief beauty 
consisting in the abundance of bright blue berries, which hang 
for many weeks on the hair-like pedicels. (B. M. 5551.) 
DIANTHERA (from dis, two, and anthera, anther; 
the cells are more or less separated from one another). 
Syn. Rhytiglossa. Including Porphyrocoma. ORD. Acan- 
асет. A rather large genus of erect, ascendent, diffuse, 
or prostrate, stove, greenhouse, or hardy herbs. Flowers 
long, solitary or fascicled, bracteate; corolla with a narrow 
_tube, which is either straight or incurved. Leaves entire, 
. or rarely dentate. For culture, see Justicia. 
D. americana (American) fl, corolla pale violet, or whitish, 
less than jin. long ; base of lower lip rugose ; peduncles ruin d 
exceeding the leaves, capitately several-flowered. Summer. i. 
narrowly lanceolate, Jin. to 4in. long, tapering at base, sub- 
sessile. Stem sulca ed. h. 1ft. to 3ft. In water, Canada 
to South Carolina, , and Texas. Hardy aquatic. 
Syn. Justicia pedunculosa (under which name it is figured in 
B. M. 2367). i 
D. ciliata (fringed).* fl. violet, with a white palate, numerous, 
fascicled. Winter. 1. ovate-lanceolate, 2in. to Sin. long. A. 2ft. 
Venezuela, 1870. A pretty stove sub-shrub. Syn. Beloperone 
ciliata. (B. M. 5888.) 
D. Pohliana (Pohys)* Л. purple; bracts deep red, imbricated, 
rather large; spike terminating the branches, closely packed, 
cone-like. March. J. somewhat large, sessile, narrowed to both 
ends. Brazil, 1880. Stove. Syn. Porphyrocoma lanceolata, 
(B. M. 4176.) í 
D. secunda (side- flowering) Л. red, in compound terminal

fragrance of the blossoms of most of the species, as well as 
from their unrivalled neatness and brillianey). Pink. 
ORD. Caryophyllee. Tufted, mostly glaucous herbs, often 
shrubby at the base. Flowers rose or 
purple, rarely white or yellow, terminal, 
solitary, panicled or fascicled; calyx tubu- 
lar, five-toothed, furnished at the base with 
imbricating bracts (see Fig. 643); petals 
five, entire or cut, with long claws. 
Leaves narrow, grass-like. This genus con- 
sists of about seventy species, according 
to the authors of the “ Genera Plantarum,” 
although more than four times that num- 
ber have been aceorded specifio rank by 
various botanists. Just a hundred are re- 
garded as species by Nyman, in his 
enumeration of European plants. The
