NOTES ON FLOAVERS. 
Ternate (ternatus) ; growing three together 
from the same point, as the leaflets of Meny- 
anthes trifoliata, and some clematises. 
Thallus; the leaf-like expansion of a lichen : 
it is the union of stem and leaf in these and 
some allied tribes of imperfect plants. 
Trapeziform (trayieziformis) ; having the 
form of a trapezium ; a figure with four 
straight sides, not parallel, and of unequal 
length, as in the leaf of Populus nigra. 
Triangular {triangularis) ; having the 
figure of a triangle, as in the leaf of Betula 
alba. 
Vagina ; the sheath formed by the convolu- 
tion of a flat petiole around the stem, as seen 
in the case of grasses. 
Vasculum ; a term applied to the fistular 
modification of the petiole of some plants, 
which is called a pitcher. 
Veins; the ramifications of the petiole among 
the cellular matter of the leaf. 
Veinless ; applied to leaves which are with- 
out veins. 
Veinlets ; the smaller veins of the leaf. 
Vernation ; the manner in which young 
leaves are arranged in the leaf buds. 
Verticillate (verticillatus) ; whorled ; where 
several leaves are in opposition round a com- 
mon axis, as in the phyllodia of Acacia verti- 
cillata. 
Vernation ; the manner of the distribution 
of the veins of a leaf. 
Volva; a wrapper ; the involucrum-like base 
of the stipes of a mushroom : this is originally 
a bag enveloping the whole plant, and is left 
at the foot of the stipes when the plant elon- 
gates and bursts through it. 
Vrille ; a French term for tendril. 
Waxy (undulatits) ; having an uneven, 
alternately concave and convex margin, as in 
the leaf of the holly. 
Winged (alatus) ; when the blade of the 
leaf is apparently continued down the petiole, 
so that the petiole has a foliaceous margin. 
Stems are sometimes winged in the same way. 
Whorled (verticillatus) ; applied when seve- 
ral leaves are situated opposite on the stem, as 
in Asperula odorata. 
NOTES ON FLOWERS AND FLOWERING 
PLANTS. 
Obeliscaria Drummondii, Graham 
(Drummond's Obeliscaria). — Asteraceae § 
Tubulifloras - Senecionideas. — A herbaceous 
perennial, growing two feet high, with many 
nearly simple (unbranched) stems, deeply ly- 
rate-pinnatifid leaves, with from three to 
seven linear-oblong lobes ; the flowers gixnv 
singly at the top of the very long stalks, and 
are large and strong ; the florets of the ray 
(what would be called petals) are five, with a 
semiorbicular limb, and are bright yellow, the 
lower half stained with deep brown ; in the 
centre the florets of the disk are collected into 
an ovate form. A native of North America. 
Introduced in 1836. Flowers in July and 
August. It is also known as Hudbeckia JDrum- 
mondii (F&xton). Culture. — Hardy; grows in 
ordinary garden soil ; propagated by division 
of the plant and by seeds. 
Stephanotis eloribunda, A. Brogniart 
(many-flowered Stephanotis). — Asclepiadaceas 
§ Stapelite. — A shrubby climbing plant of 
vigorous habit, with evergreen opposite ovate- 
elliptical, thick, smooth, shining, dark-green 
leaves, and umbels of large white fragrant 
flowers; the stalk of the umbels is inserted 
laterally between the stalks of the leaves ; the 
flowers consist of a tube about an inch long, 
swollen at the base, and spreading at the apex 
into five oval segments, pure white, and deli- 
riously fragrant. A native of Madagascar. 
Introduced in 1835. (?) Flowers in May, 
June, and July. Culture. — Requires a stove, 
and either a large pot and trellis, or to be 
planted against a pillar ; peat and loam ; pro- 
pagated by cuttings. 
Bomarea acutifolia, Herbert (sharp- 
leaved Bomarea). — Amaryllidaceaa § Alstro- 
nierieas. — A tuberous-rooted herbaceous plant, 
(nearly evergreen in a greenhouse) with twin- 
ing stems, twelve to twenty feet long, clothed 
with scattered lanceolate leaves, slightly hairy 
underneath and about half an inch wide, and 
terminated by a bunch of flowers, each about 
one inch long; the flowers are in six segments, 
tubular, the three inner segments orange- 
coloured, the outer ones red. A native of 
Mexico. Introduced in 1829. Flowers in 
August and September. Known also as Al- 
stromeria acutifolia (Otto). Culture. — 
Hardy in a sheltered place, with slight protec- 
tion in winter ; sandy loam ; propagates by 
seeds or division of the root. 
Cypella Herberti, Herbert (Herbert's 
Cy pella). — Iridaceaa. — A slender bulbous plant, 
growing about two feet high, with broadly 
linear-lanceolate plaited leaves, and a flexuose 
regularly two-forked flower-stem, bearing 
large showy orange-coloured flowers in a 
loose panicle; the flowers consist of six divi- 
sions, the three outer ones large, spreading, 
and undulated, the inner ones much smaller, 
and forming a double curve, so as to be very 
much recurvate at the apex. A native of 
Buenos Ayres. Introduced in 1823. Flowers 
in June and July. It also bears the names of 
Tigridia Herberti (Herbert) and Morcea 
Herberti (Lindley). Culture. — Requires a 
frame, Or a dry position out doors, such as a 
south aspected border, well drained ; peat and 
sandy loam ; propagated by seeds or by off- 
sets.
