PHACELIA 



PH^NOCOMA 



12. congesta, Hook. (P. conferta, Don). Pubescent 

 and commonly cinereous erect annual, hardly viscid or 

 glandular in the least, a foot or more high : Ivs. pinnately 

 3-7-divided or -parted, and with a few interposed small 

 lobes, the main divisions oblong or oval, incisely pin- 

 natifid or irregularly lobed, the lower ones mostly 

 petiolate and the upper confluent: calyx-lobes linear or 

 somewhat spatulate; corolla blue, 3 lines long, the lobes 

 as long as the tube; stamens more or less exserted: 

 seeds reticulate scabrous, the fine sharp meshes being, 

 as it were, toothed at the junctions. Texas, New Mex. 

 B.M. 3452. V. 5:154; 12:140. 



13. tanacetifdlia, Benth. (P. tripinnata, Hort.). 

 Erect annual, often cult., roughish hirsute or hispid, 

 not glandular, or above slightly so, 1-3 ft. high: Ivs. 

 pinnately 9-17-divided into linear or oblong-linear once 

 or twice pinnately parted or cleft divisions, all sessile 

 or nearly so, the lobes mostly linear-oblong: spikes 

 cymosely clustered, at length elongated: very short 

 fruiting pedicels ascending or erect: calyx-lobes linear 

 or linear-spatulate, not twice the length of the ellipsoidal 

 caps. ; stamens and style conspicuously exserted : seeds 

 with very narrow pits bounded by thick walls. Calif. 

 B.M. 3703. B.R. 1696. Said to be sometimes cult, as a 

 bee-plant. According to Jepson, "Cows fed on it show 

 a marked increase in yield of milk but will not eat it 

 alone at first." Variable. Var. alba, Hort., has been 

 offered. L. F. HENDERSON.

PHJEDRANASSA (Greek, gay queen, suggested by 

 the beauty of the flowers). Amaryllidacese. Tender 

 mostly sximmer-blooming bulbs, with flowers that are 

 tubular in appearance, borne in umbels, generally 

 drooping and usually bright red with green tips. 



Bulb tunicated : fls. on a peduncle or scape 10 in. to 

 2 or 3 ft. long; perianth subcylindrical; segms. 6, equal, 

 regular, spreading only at the tip; stamens inserted at 

 or below the throat of the tube; ovary 3-celled; ovules 

 many, superposed: caps, globose, loculicidally 3-valved; 

 seeds many, small, black: Ivs. petioled, oblong or lan- 

 ceolate, produced after the fls. according to Baker, 

 but this point is doubtful for all species. Species 4 or 

 5, in the Andes at 7,000-12,000 ft., except P. Carmiolii, 

 a native of Costa Rica, which differs from all other 

 species in having the perianth-segms. much shorter 

 than the tube. Probably the choicest species is P. 

 chloracra, the tube of which seems at first sight over 2 

 in. long; however, the segms. are merely connivent and 

 it is only for a distance of Min. at the base that they 

 are really grown together into a tube. This species has 

 6-12 fls. in an umbel. P. gloriosa, Hort., recommended 

 by some dealers, seems to be unknown to botanists. The 

 species are kept rather dry in winter, and bloomed in the 

 open or perhaps under glass in spring, summer, or 

 autumn ; prop, by offsets. They apparently thrive under 

 the treatment afforded by a cool greenhouse. 



A. Tube of perianth much shorter than the segms. 

 B. Fls. chiefly red. 



chloracra, Herb. (P. obtusa, Herb. Crinum quitense, 

 Spreng.). Bulb globose, 2-3 in. thick: Ivs. produced 

 after the fls.; blade 8-12 in. long, 2-3 in. wide, oblong- 

 lanceolate and acute, the petiole clasping: peduncle 2-3 

 ft. long, nearly terete, glaucous; fls. scarlet, tipped 

 green, 6-12 in the umbel, usually drooping, l^2~2 in. 

 long. Andes of Ecuador, to 12,000 ft. B.M. 5361. B.R. 

 31:17. The name is sometimes erroneously written 

 P. chloracea. 



BB. Fls. chiefly green. 



viridifldra, Baker. Bulb ovoid, 1*4 in. thick: If. 

 solitary, bright green, lanceolate, nearly 1 ft. long; 

 petiole short: peduncle 1 ft. long, terete; fls. about 4 in 

 an umbel, green toward the tip, without any red, 

 passing into whitish toward the base, drooping, the 



perianth-limb 1J4-1M in- long. Andes of Ecuador. 

 Possibly a color variety of P. chloracra. 



AA. Tube of perianth much longer than segms. 



Carmi61ii, Baker. Bulb globose, 2-3 in. diam.: Ivs. 

 1-2, equaling peduncle, oblong-lanceolate, acute, bright 

 green, the petiole much shorter than blade: peduncle 

 about 2 ft. long, terete, pale glaucous-green, bearing 

 8-10 fls. in an umbel; fls. with perianth-limb 2 in. long, 

 the bright red tube cylindrical and 3 tunes as long as 

 the oblong-lanceolate green pale-edged segms.; stamens 

 exserted. Costa Rica. B.M. 8356, where it is said the 

 plant requires complete rest after the Ivs. die down. 

 "The tall fl.-stalk precedes the Ivs., which, however, 

 develop while the plant is hi flower."

PRffiDRANTHUS (Greek for, splendent or gay, and 

 flower, alluding to the brilliantly colored flowers). Big- 

 nonidcese. Ornamental vine grown for its very showy 

 flowers and also for its handsome foliage. 



Evergreen climbing shrub: Ivs. opposite, with 1 pair 

 of entire Ifts., the terminal 1ft. usually replaced by a 

 3-parted or repeatedly 3-parted tendril : fls. in terminal 

 racemes; calyx campanulate, 5-10-nerved, leathery, 

 tomentose, with 5 unequal short teeth; corolla tubular- 

 funnelform, curved; stamens slightly exserted; disk 

 annular, raised; ovary ovoid, tomentose, with many 

 ovules in several rows.-^-One species in Mex. Formerly 

 usually referred to Bignpnia, from which it differs 

 chiefly in the slender filiform tendrils, the leathery 

 tomentose calyx, the exserted stamens and tomentose 

 ovary. A very handsome strong-growing vine for 

 subtropical regions or in the N. for the cool greenhouse; 

 one of the most showy bignoniads on account of its 

 large brilliantly colored fls. For cult, and prop., see 

 Bignonia. 



buccinatorius, Miers (Bignonia Cherere, Lindl. B. 

 Kerere, Hort., not Aubl. B. buccinatdria, Mairet). Tall 

 tendril-climber; branches obtusely angled: Ifts. 2, or 

 sometimes 3, elliptic to ovate-oblong, cuspidate or 

 obtuse, thinly coriaceous, glabrous and lustrous above, 

 tomentose beneath while young, later hairy only on 

 the veins, glandular, 2-3 in. long: fls. pendulous, in 

 terminal racemes with erect stout and short rachis; 

 calyx 2^in. long; corolla 4 in. long, blood-red, yellow at 

 the base, lobes spreading, emarginate, about Kin. long.

PK/ENOCOMA (shining hair, Greek, alluding to the 

 involucre). Compdsitse. A South African little shrub, 

 sometimes grown under glass for the showy flower- 

 heads. 



Of the Gnaphalium-Helipterum-Helichrysum rela- 

 tion, one species: heads heterogamous, very many-fld., 

 showy because of the brilliant and elongated inner scales 

 of the involucre; florets all tubular and 5-toothed, the 

 marginal female and in a single row, the others male 

 with abortive stigma; receptacle naked; pappus of 

 many rough bristles in a single row, equaling the corolla, 

 somewhat unlike as between the female and male fls. 

 The stiff parts of the involucre make it useful as an 

 everlasting, for which use it is a very showy subject. 



These are handsome and distinct evergreen plants. 

 They need a cool airy and shaded house during the 

 summer. They should have plenty of ventilation in 

 the spring and well into the autumn; this will tend 

 greatly to solidify the growth, this causing the greater 

 production of flowers. It is better to place the pots on 

 screened coal-ashes, as this helps to keep the roots cool 

 and moist. They are better if kept by themselves, as 

 they should not be syringed. Watering is a matter of 

 great importance at all seasons. They need some stak- 

 ing and tying so as to keep them in shape. When the 

 weather is cool enough, they should have a temperature
