 a cell or capsule; alluding to the stalk of the fruit). 

 SYNS. LophocHnium, Phcenopoda, Podosperma. OBD. Com- 

 posite. A genus comprising five species of glabrous or 

 scabrous-pubescent, erect, hardy, Australian annnala, 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 campanula te. 

 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. gnapbalioides (Gnaphalinm-like). JL-htadtou long peduncles ; 

 florets very slender, considerably longer than the involucre and 

 pappus. June. I. linear or lanceolate, the lower ones narrowed 

 below the middle, all stem -clasping, and sometimes shortly de- 

 current. A. 1ft. to lift. 184L (B. M. 3920.)

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

 female ; referring to the villous style). OBD. Labiate. A 

 small genus (sir species) of dwarf or erect, hardy 

 annuals, natives of California. Flowers whorled, collected 

 into dense, leafy spikes ; calyx campannlate, 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. Donglasil (Douglas'). JL, corolla purple or dark violet ; lower 

 calyx teeth thrice as long as the tube ; bracts linear, acute, almost 

 leaf-like ; spikes oblong, 2in. to Sin. long. August. I. petiolate, 

 lin. to Ijin. long, oblong, obtuse, entire, gradually narrowed to 

 the base, glabrous. Stem slightly branched. h. 1ft 187L (B. M. 

 5886.)

 er shorter bracts than the type.

 Greek compounds, and denotes any collection of long 

 hairs. 



POGONELLA. A synonym of Simethis (which 

 see). 



FOGONXA (from pogonias, bearded ; referring to the 

 fringed lip of some of the original species). Including 

 Cleistes and Triphora, OBD. Orchideae. 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-mentioned 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 

 growth recommences the following season. All do well

 acuminate, dirty-yellowish, with three brown nerves; lip as 

 long as the sepals, glabrous, convolute portion white; lobes 

 rose-coloured. L shortly stalked, orbicular, acute, plaited by 

 about twelve strong nerves ; upper surface dull brownish-green 

 and purple, sparsely clothed with crystalline, cellular hairs; 

 under surface rose-coloured. Hong Kong, 1885. SYS. P. puldulla
