PODOTHECA (from pous, podos, a foot, and theke, 
a cell or capsule; alluding to the stalk of the fruit). 
Syns. Lophoclinium, Phenopoda, Podosperma. ORD. Com- 
posite. A genus comprising five species of glabrous or 
scabrous-pubescent, erect, hardy, Australian annuals, not 
woolly, or rarely the involucre very slightly so. Flower- 
heads yellow, homogamous, rather large, sometimes very 
long, on terminal peduncles, usually dilated under the 
involucre ; involucre cylindrical, conical, or campanulate, 
with imbricated, herbaceous bracts; receptacle without 
scales; florets tubular, five-toothed. P. gnaphalioides is 
a plant of little beauty ; it thrives in any ordinary garden 
soil, and may be readily increased by seeds. 
P. gnaphalioides (Gnaphalium-like). /l.-heads on long peduncles ; 
florets very slender, considerably longer than the involucre and 
June. J. linear or lanceolate, the lower ones narrowed

POGOGYNE (from pogon, a beard, and gyne, a

small genus (six species) of dwarf or erect, hardy 
annuals, natives of California. Flowers whorled, collected 
into dense, leafy spikes; calyx campanulate, five-toothed ; 
corolla with a straight, exserted tube, and a bilabiate limb. 
Nutlets ovoid, smooth. Leaves linear, entire, or the 
upper or floral ones slightly conformed, long-ciliated, 
somewhat toothed. P. Douglasii is the only species in- 
troduced. Seed should be sown in pots, and the seedlings 
turned out into the open border. 
P. Douglasii (Douglas’). fl., corolla purple or darkviolet ; lower 
calyx teeth thrice as long as the tube ; bracts linear, acute, almost 
leaf-like ; spikes oblong, 2in. to 3in. long. August. l. petiolate, 
lin. to ljin. long, oblong, obtuse, entire, gradually narrowed to 
— bape glabrous. Stem slightly branched, h. 1ft. 1871. (B. M. 
P. D. multiflora (many-flowered). A smaller form, with lilac 
corolla, and rather shorter bracts than the type. 
POGON. A beard. The word is largely used in 
Greek compounds, and denotes any collection of long 
hairs. 
POGONELLA. A synonym of Simethis (which 
see). 
POGONIA (from pogonias, bearded ; referring to the 
fringed lip of some of the original species). Including 
Cleistes and Triphora. ORD. Orchidew. A genus com- 
prising upwards of thirty species of stove, terrestrial 
orchids, with spherical tubers, broadly dispersed over the 
globe. Flowers solitary or loosely racemose, having free, 
conniving, or somewhat ringent sepals and petals, either 
all equal or the petals smaller; a free, erect, undivided 
or lobed lip, with its disk crested or papillose; a long, 
semi-terete, clavate column, eared or winged at the top; 
and a sessile or very shortly stalked two-celled anther, 
containing two furrowed pollen masses. Plants either 
having one or a few sessile leaves upon an erect stem 
at the period of flowering, or leafless till after flower- 
ing, and then producing a solitary, stalked leaf from an 
underground stem. The under tioned species thrive 
in well-drained pots or pans of open, loamy soil, amongst 
which is intermixed living sphagnum. An abundance 
of water is required during the season of growth, but 
after the leaves die off none must be administered until

P. discolor (different-coloured). fl. in pairs, lżin. in diameter ; 
sepals and petals dirty grey-green, jin. long, spreading ; lip white, 
with a green disk, convolute; scape solitary, 2in. to 3in, long. 
l. solitary, 3in. to in. in diameter, nearly horizontal, orbicular- 
cordate ; — surface dark rufous-green, often with paler blue- 
green blotches, bristly ; under surface dull purple, less bristly.

with terete branchlets, natives of tropical America. 
Flowers pink, showy, pedicellate, disposed in terminal, 
branched panicles; calyx five-toothed, deciduous ; corolla 
with an elongated tube and a limb of five short, valvate 
lobes. Leaves opposite, petiolate, ample, membranous;

to Mussenda (which see).

A genus comprising about thirty species of stove or 
greenhouse herbs (or shrubs?), natives of the East 
Indies, the Malayan Archipelago, and Japan. Flowers 
disposed in many- or rarely few-flowered whorls; calyx 
ovoid-tubular, equal, five-toothed, often elongated during
