RHAPHIDOPHORA (Greek for }n'r>]Ir-/>rn ri u,j: allud- 

 ing to needle-like hairs). Araccir. Abuut '2t) sppcips oP 

 the East Indies, allied to Potho.s, but distino;uisljcd from 

 the Pothos tribe by the presence of odd hairs in the in- 

 tercellular spaces and by the 2-loculed rather than 3- 

 loculed ovary. See Potlios. It is probable that the gar- 

 den plant PotJios aure/(.'< is of this genus. Rhapbido- 

 phoras are climbing aroids, to be treated like Philoden- 

 dron and Pothos. 



It is not kno\yn that any species of Rhaphidophora 

 are in the American trade, it*, pertusa, Schott (i?. phi- 

 v(lta, Schott. Schiddpsus perfi(sus, Schott), has large 

 monstera-like Ivs., with long and narrow side lobes and 

 numerous holes in the blade. R.H. 1883, p. 551. J?, de-

 nate Ivs., the segments or Ifts. oblong-lanceolate-acu- 

 minate and strongly nerved; spathe yellowish. B.M.

 oblong Ivs., with roundish or subcorilate base; spathe 

 yellowish. 



RHAPIDOPHt'LLUM (Greek, probably means BJiapis- 

 leaved). Pahnar^',v. Blue Palmetto. A genus of one 

 species ranging from South Carolina to Florida. It is 

 a dwarf fan-palm with erect or creeping triink 2-3 ft. 

 long, and long-stalked Ivs. with about 15 segments. 

 The genus is closely allb-d to Cham^erops and is distin- 

 guished by having tbe albumen not ruminate a.nd by the 

 bracts at tiie base of tbe branches of the spadix being 

 few or none. 



Other generic characters: spadicps s]iort-y)edn]icled : 

 spathes 2-5, entire, tubular, compressed, Idlid, woolly: 

 fls minute, orange: fr. small, ovoid or obovale, woolly. 

 The plant is said to produce suckers freely, like Rhapis, 

 an ttnusual circumstance among palms.

Bha pidoplnfl! n hi Hi/strix, the Blue Palmettoor Needle 

 Palmetto, is (be most tieautiful and elegant of our 

 native dwarf palms. It is very local in its distribution, 

 lieiniz' fouml iu rich, low soil both in Georgia and .Florida, 

 but it is cverN'wliert.; rather rare. Its most striking char- 

 acteristics are tbo long, sharp, hlack 

 spines ]ii-oje('ting in every direction from 

 the <hirk libers which cover the trunk.

RHAPIOLEPIS. See Baphiolepiy. 



RHAPIS (Greek, needle; alluding to 

 the shape of the Ivs. or perhaps the awns 

 of the corolla). Pahnncen-. A genus of 

 5 species of fan-palms of very distinct 

 habit, natives of China and Japan. They 

 are among the few ]iahiis that produce 

 suckers at the ba^e. tber<diy forming 

 bushy clumps, how pahns, with leafy, 

 densely ces])itosr n--edy stems clothed 

 with remains of the reticulate leaf- 

 sheaths : h^s. alternate and terminal, 

 sub -membranaceous, connate or semi- 

 'trbicular, irregularly and digitately 3- to 

 nuiuy-parted; segments linear, cuneate, 

 or elliptical truncate, entire, dentate or 

 lobed: nerves 3 to many; transverse 

 veins conspicuous; rachis none; lignle 

 very short, semi-circular; petiole slen 

 der, biconvex, smooth or serrulate on 

 the margins; sheath long, loosely fringed 

 on the margin; spadices shorter than the 

 Ivs., slender-peduncled : rachis sheathed 

 by deciduous bracts: branches spread- 

 ing: spathes 2-3, incomx>lete, membra- 

 nous: fls. yellow. This genus is .distin- 

 guished from its near allies (for a list 

 of which see Licuala) by the fls. being 

 dicecious; corolla 3-toothed; anthers de- 

 hiscing extrorsely. The name Rhapis is 

 commonly spelled and pronounced Ra- 

 phis, hut this is incorrect.
