FHLJJUM (from Phleos, an old Greek plant name 

 used by Theophrastus). SYN. Stelephuros. OBD. Gra- 

 minece. A genus comprising about half-a-score species 

 of hardy, annual or perennial, erect grasses, natives of 

 Europe, Central and North Aria, North Africa, and 

 North and Antarctic America. Panicle rather long, 

 pedunculate, always densely spike-formed, sometimes 

 elongated, narrow-cylindrical, sometimes shorter, oblong 

 or scarcely ovoid, often pubescent ; spikelets one- flowered, 

 with rarely a rudimentary second flower ; glumes three ; 

 stamens three. P. alpinum, P. arenarium, P. phalaroides 

 (P. BoeJimen), and P. pratense (Cat's Tail, or Timothy 

 Grass), are natives of Britain. The species have no 

 horticultural value. 



FHIiOGACANTHUS (from phlox, phlogos, flame, 

 and Acanthus ; from the flame-coloured flowers of some 

 species). STN. Lozanthus. OBD. Acanthaceas. This genus 

 contains about twelve species of tall, stove shrubs or 

 herbs, inhabiting the Himalayan Mountains and Mar- 

 taban. Flowers whitish, reddish, or greenish, cymose; 

 cymes disposed in long, thyrsoid, terminal spikes, or axil- 

 lary and shorter ; corolla tube large, incurved. Leaves 

 entire, or slightly toothed, often large. For culture, see 

 Jnsticia.

 what funnel-shaped ; tube short, rather gibbous at base ; spike 

 terminal, on a quadrangular peduncle. January. L large, oppo- 

 site, remote, broadly ovate-lanceolate, obscurely serrate, entire

 Shrub. (B. M. 2845 and B. R. 1340, under name of Juttida

 P. curvifiorns (curved-flowered).* A. yellowish, with an elongated 

 corolla. November, i. large, elliptic, acute at both ends, toothed, 

 glabrous. Stems quadrangular, downy. A. Sit. to 6ft Khasia 

 Mountains, 1839. Shrub. (B. M. 3783.)

 racemes terminal. Spring. I. oblong, attenuated at both ends, 

 ub-crenulated. h. 2ft India, 1828. Herb. (B. B. 1334.) 



PHLOMIS (the old Greek name used by Dioscorides). 

 OBD. Labiate. A genus of tomentose, woolly, canescent, 

 or greenish, mostly hardy herbs, sub-shrubs, or shrubs, 

 inhabiting temperate and mountainous Asia and the 

 Mediterranean region. Upwards of seventy plants have 

 been described as species, but, probably, not more than 

 fifty are sufficiently distinct to merit specific rank. 

 Flowers yellow, purple, or white; corolla with an in- 

 closed or scarcely exserted tube, the upper lip com- 

 pressed, entire or notched, tomentose or villous, sessile, 

 and the lower three-cleft and spreading; whorls many- 

 flowered, axillary; bracteoles often numerous, ovate, lan- 

 ceolate, or narrow, appressed. Nutlets ovoid-triquetrous. 

 Leaves wrinkled; floral ones conformed, or the upper- 

 most ones diminutive. All the species are of easy culture 

 in ordinary garden soil; they are well adapted for 

 naturalising in shrubberies, wild banks, and borders. Ml 

 may be increased by seeds; the shrubby sorts also by 

 cuttings, and the herbaceous kinds by division. The 

 under-mentioned species are those best known to cultiva- 

 tion, and are, except where otherwise indicated, hardy 

 perennial herbs.
