PHOENIX 



PHORADENDRON 



opposite and alternate, 2-ranked, ensiform, with fili- 

 form tips, whitish or mealy beneath; petioles 3-5 ft. 

 long, slender, scurfy, with many long spines; sheath 

 fibrous: fr. black-purple. Along rivers and bays. 

 Trop. Asia. R.H. 1912, p. 423. 



BB. Arrangement of Ifts. 2~4 or many-ranked. 



c. Position of Ifts. equidistant. 



D. Color oj Ivs. dark green. 



4. p'usflla, Gaertn. (P. farinifera, Roxbg.). Shrubby: 

 caudex at most 4 ft., thickly clothed with old If .-sheaths: 

 petiole with 1 or 2 pairs of spines; Ifts. subopposite, 

 4-ranked, ensiform, rigid, pungent, dark green: fr. 

 black. Ceylon and S. India. The caudex is said to 

 have a farinaceous pith, and the foliage to be so spiny 

 that it is impossible to walk through clumps of it. 



DD. Color of Ivs. light green. 



5. zeylanica, Hort. (P. pusilla, Becc., not Gaertn.). 

 St. 8-20 ft. high, rarely much shorter: Ivs. rather short; 

 Ifts. very many, subequidistant, 7-10 in. long, bright 

 green, quadrifariously inserted, linear-lanceolate: fr. 

 obovoid-oblong, red at length violet-blue, 3^in. long. 

 Ceylon. Fr. edible. 



cc. Position of Ifts. grouped or fascicled. 



r>. St. bulbiform: Ivs. short. 

 E. Lfts. scattered, irregularly fascicled. 



6. humilis, Royle. Sts. short, tufted, bulbiform, 

 rarely elongated: Ivs. subglaucous; Ifts. scattered, 

 interruptedly fascicled. Very close to P. acaulis, but 

 distinguished by the very long-peduncled, fruiting 

 spadix. Hilly districts of India. Var. Hanceana, Becc. 

 (P. Hanceana, Hort.), from China, is cult. 



7. Roebelenii, O'Brien. Figs. 2918 2 2919. Lvs. 1 

 ft. or more long; Ifts. 5-7 in. long, shining, dark green, 

 soft, curved, subglaucous, often approximate, mostly 

 falcate, not spinous at the tip. Assam to Cochin- 

 China. G.M. 38:80; 53:996. A.G. 15:201. G.C. III.

 6:289. J.H. III. 64:76. Gt. 61, p. 392. This dwarf 

 palm, like a date palm but only about 2 ft. high, is 

 variously understood. Beccari ; in Webbia, vol. 3 

 (1910), treats it as a valid species; but Blatter subse- 

 quently, in Journ. Bombay Nat. Hist. Soc., makes it a 

 synonym of P. humilis var. Loureirii, Becc. 



EE. Lfts. in nearly opposite fascicles. 



8. acaulis, Buch. Caudex bulbiform, 8-10 in. diam., 

 densely clothed with sheaths and bases of spiny petioles: 

 Ivs. 2-6 ft.; Ifts. in subopposite fascicles, many-ranked, 

 y^r\y^ ft. long, very rigid, somewhat glaucous, marginal 

 nerve very strong; petiole 1 ft. or more, with many 

 spines: fr. bright red to blue-black. India. 



DD. St. erect: Ivs. long. 



E. Lvs. very slender. 



9. pihnila, Hort. St. slender, graceful, 6-10 ft. : Ivs. 

 10-16 ft. long, recurved, drooping; Ifts. 8-12 in. long, 

 4-ranked. Gt. 20, p. 173 (desc.). 



10. canariensis, Hort. (P. tennis, Versch. P. Jubse, 

 Webb). Resembling P. dactylifera, but more slender 

 and graceful in all its parts: Ivs. more numerous.

 68:446. Var. macrocarpa is cult, in Florida. 



EE. Lvs. more robust. 



F. Foliage glabrous. 



11. sylvestris, Roxbg. St. solitary, stout, 25-40 ft. 

 high, clothed with persistent petiole-bases, the crown 

 very large: Ivs. 10-15 ft., glabrous, grayish green; 



petiole spiny; Ifts. 1-2 ft., fascicled, 6-18 in. long and 

 %-l in. broad, 2-4-ranked, rigid: fr. orange-yellow, the 

 seed rounded at both ends, pale brown. Very close to P. 

 dactylifera and perhaps the origin of that plant. India.

 A hybrid of P. sylvestris and P. canariensis secured by 

 E. H. Hart is highly praised. 



FF. Foliage glaucous. 



12. dactylifera, Linn. (P. cycadifolia, Hort.). DATE 

 PALM. Fig. 2920. St. erect, to 100 ft. and more: Ivs. 

 glaucous, arcuate-ascending; Ifts. linear-lanceolate, 

 acuminate, 8-16 in. long, strongly complicate, the lower 

 4-ranked, the upper 2-ranked, irregularly and remotely 

 aggregate: fr. cylindrical-elliptical, 1-2 in. long. Arabia, 

 N. Afr. R.H. 1893, p. 127; 1912, p. 109. G.W. 11, p. 

 24. Var. excelsa, Hort., is cult, in Fla. See Date. 



P. andamanensis, Hort. Similar to P. rupicola, but more 

 elegant, differing from those in cult, by the regularity of its pinna 

 and narrowness of the terminal one. Andaman Isls. P. dumdsa, 

 Hort. Saul, 1893. Of "dwarf habit." Seems unknown to botanists. 

 P. natalensis and var. variegata are offered, but no description is 

 available. P. paradtnia is advertised. P. Sanderidna. Presumably 

 intro. within recent years by Sander & Co., St. Albans, England.

PHOLZDOCARPUS (Greek, scale and fruit: the 

 fruit is covered with a scaly coat). Palmdcese. A palm 

 of the oriental tropics. Trunk tall: Ivs. orbicular, 4-5- 



Earted ; petiole spinous : f r . globose or ovoid with a tessel- 

 ited pericarp; seed laterally inserted. About 5 spe- 

 cies, Malaya, all very imperfectly known. One spe- 

 cies, P. Ihur, Blume, is sometimes grown in the warm- 

 house and may be suitable for outdoor growth in S. 

 Calif. This has Ivs. similar to those of Borassus flabel- 

 lifer, the petioles are armed with stout spines, the spa- 

 dix loosely branched and the drupe ovoid, about as 

 large as a fair-sized hen's egg, the rind rugose and tes- 

 sellated and has 3 4 seeds. Malaya. 



PHOLIDOTA (Greek, scale and ear; the scales of the 

 unopened raceme are said to recall the rattle of a 

 snake). Orchidacex. Orchids with the habit of Coe- 

 logyne, to be grown in a warmhouse, 55 to 65. 



Rhizomes creeping: pseudobulbs consisting of a sin- 

 gle internode: fls. small, short-pedicelled, in slender 

 racemes, each with a large bract; sepals and petals short, 

 broad; labellum excavated or sac-like; column very 

 short, winged around the top. A small genus contain- 

 ing about 20 species, natives of India, S. China, and the 

 Malay Archipelago. For cult., use strong light rich 

 potting material, broken pots, old dry cow-manure, 

 plenty of drainage. Do not allow to become very dry. 



imbricata, Lindl. Pseudobulbs oblong sulcate: Ivs. 

 oblong-lanceolate, plicate, 6-12 in. long: raceme long- 

 peduncled, 3-8 in. long; fls. small, rather crowded on 

 the raceme, white or yellowish, with a shade of violet. 

 Feb.-May. India. B.R. 1213; 1777. L.B.C. 20:1934. 



chinensis, Lindl. A small creeping epiphyte: pseu- 

 dobulbs cespitose, 1-2-lvd.: lys. oblong-undulate, acu- 

 minate: fls. greenish white, in drooping racemes not 

 more than 2-3 in. long; sepals ovate; petals linear; 

 labellum oblong, recurved. This plant has long been 

 known from Chinese drawings.

PHORADENDRON (Greek, tree thief}. Loran- 

 thacese. The mistletoe of E. N. Amer. is P. flavescens, 

 Nutt. (Viscum flavescens, Pursh), Fig. 2921. It is 

 parasitic on deciduous trees as far north as N. J. and 

 S. Ind. and extending southward to Fla. and Texas; 

 also Calif. F.R. 3:590. It makes dense bunches 1-3 ft. 

 across, with thick oval or obovate yellowish green ever- 

 green Ivs. The forking twigs are terete, and break 

 easily at the base. The fls. are dioecious, borne in very
