1900 SUPPLEMENT—RECENT INTRODUCTIONS, &c. 351 
ERISMA (from erisma, strife; in reference to the 
difficulty experienced in locating the genus in the natural 
arrangement). Syns. Debrea, Dittmaria. ORD. Vochy- 
siacee. A small genus (four species) of stove trees, natives 
of Northern Brazil and Guiana, and closely allied to 
Qualea. Flowers small or rather large, paniculate. Leayes 
opposite, petiolate, coriaceous. Some of the species attain 
a great size in their native places. EH. floribundum has 
been introduced, but is probably lost to cultivation. 
ERITHALIS. Syn. Herrera. Flowers usually in 
terminal, pedunculate, erect panicles, very rarely solitary ; 
calyx limb truncate or fiye- to ten-toothed; corolla salver- 
shaped or rotate, with five to ten lobes. Leaves opposite, 
petiolate, coriaceons, elliptic, obovate or lanceolate. 
E. odorifera (scent-bearing). A synonym of E. /fruticosa. 
ERITHALIS (of Forster). A synonym of Timonius 
(which see). 
ERITRICHIUM. Bentham and Hooker include 
Krynitzkia and Plagiobothrys hereunder. ‘This genus 
comprises about seventy species. Flowers blue or white, 
in simple or branched racemes, or rarely nearly all axillary ; 
calyx deeply five-cleft or five-partite ; corolla tube short or 
rarely longer than the calyx, the lobes five, imbricated, 
obtuse, spreading; stamens five, affixed to the tube, 
included. Nutlets four, or fewer by abortion. Leaves 
alternate or (in very few species) opposite, usually narrow. 
To the species described on p. 529, Vol. I., the following 
should be added : 
E. barbigerum (beard-bearing).* /l. white, small, much resem- 
bling those of a Myosotis, disposed in branching, scorpioid cymes; 
calyx lobes linear, about jin. long. Summer and autumn. 
7. lanceolate. California, 1886. A pretty annual; the whole 
plant clothed with long, spreading hairs. (R. G. 1886, pp. 358-9, 
1, 42; R. H. 1885, p. 552, f. 99.) According to the ‘Index 
Kewensis,” the correct name of this plant is Krynitzkia 
barbigera. 
E. nothofulvum. jl. white, sweet-scented. California, 1892. 
A hardy annual, in general appearance not unlike a Forget- 
me-not. According to the ‘Index Kewensis,” the correct name 
of this plant is Plagiobothrys nothofulvus. 
ERNDLIA. A synonym of Curcuma (which see). 
ERODENDRON. A synonym of Protea (which see). 
ERODIUM. Though the Erodiums generally are best 
accommodated on the rockery, EH. Manescavi is such a 
vigorous grower, quickly attaining a good size, that it is 
best for the herbaceous border, thriving particularly well 
im chalky soils. 
To the species described on p. 529, Vol. I., the follow- 
ing should be added: 
E. chamzdryoides (Chamedrys-like). The correct name of 
E. Reichardi. 
E. chrysanthum (golden-flowered).* l. lemon-yellow; petals 
yellow, obovate, twice as long as the calyx. Summer. J. ad- 
pressedly silvery-silky, bipinnate; segments rather broad. 
obtuse. Stem shortened, scape-like. Greece, &c., 1897. Plant 
tufted. A fine, hardy perennial. 
E. geifolium (Geum-leaved). A synonym of E. hymenodes. 
E. moschatum (Musk-like). /l. pak; petals unequal, obovate, 
equalling the calyx; peduncle long, many-flowered. May to 
July. J. pinnatisect; segments eleven to thirteen, large, ovate, 
doubly serrated. Stem ascending, rather thick. South Europe, 
North Africa, &c. Half-hardy annual. 
EROPHILA (from er, the spring, and phileo, to love ; 
in reference to the flowering period). Orb. Crucifere. A 
small genus (about five species) of small, hardy annuals, 
extending from Europe to Northern India, H. vulgaris 
(Whitlow-Grass, Syn. Draba verna) being a British plant ; 
they are closely allied to Draba. LE. przxcox has been intro- 
duced, but is of little horticultural value. 
ERPETION. Included under Viola (which see), the 
correct name of E. reniforme being V. hederacea. 
ae A synonym of Commelina (which 
see). 
ERYCINA (a name of Venus, from Mount Eryx, a 
mountain in Sicily, where she had a temple). Op. 
Orchidez. A monotypic genus. The species is a singular, 
little, Oncidium-like Orchid, but differing remarkably from 
that genus in the structure of the lip and column, the 
former being almost equally three-lobed, while the latter 
is short, thick, and wingless. For culture, see Oncidium. 
Erycina—continued. 
E. echinata (hedgehog-like). fl. gin. across; petals green; 
lip yellowish, large and flat ; racemes axillary from the base 
of the seudo-bu b, decurved, loosely many-flowered. April. 
Ll. 2i 0 4in, long, ovate-oblong, with a few brown stripes, 
Stems tufted, 2in. to 3in. high, clothed with imbricating bracts 
below and leaves above, and terminating in a small, two-leaved 
pseudo-bulb. Mexico, 1892. (B. M. 7389.) 
ERYNGIUM. These plants are suited for the flower- 
border, shrubbery, or even for lawns, but the situation 
must be well drained: damp is fatal to them. E. eburnewm 
should be treated as a half-hardy annnal. 
To the species described on pp. 529-30, Vol. L., the 
following should be added : 
E. aquaticum. The correct name is EF. yucccefoliwm.

Occasionally to be met with are: EH. campestre(Kurope), E. corni- 
culatum (Portugal), and FE. dichotomum (Mediterranean region). 
ERYSIMUM. Sepals erect; stamens free. These 
fragrant yellow Wallflower-like subjects are excellent for 
sunny spots in rockeries or in flower-borders.

should be added : 
E. arkansanum (Arkansas). A synonym or form of #. asperwm.
