PANAX 



at least its upper part. It soon splits from the base up- 

 ward for a good distance, and, indeed, before withering 

 the lower part of the corolla is much disposed to sepa- 

 rate into five claws (liberating also the lower part of 

 the filaments). The filaments are adnate to the corolla- 

 tube for a long distance and then monadelphous and 

 adnate on one side or the other. 



debilis, Gray. Slender, glabrous, branching herb: 

 Ivs. alternate, linear-lanceolate, entire, sessile, 2-3 in. 

 long ; floral ones gradually reduced to bracts : raceme 

 lax, few-fld. : corolla-tube whitish, 9 lines long, lobes 

 light blue, 2 of them smaller than the others, the larger 

 ones 3-4 lines long. Var. serrata, Gray, was offered in 1881 

 by E. Gillett, but it is probably not in cult, anywhere. 



PALMETTO. See Sabal.

PALUMBtNA (said to be from pa'lumbes, wood-pig- 

 eon; from a supposed resemblance of the fls.). Orchi- 

 dacece. A monotypic genus greatly resembling Oncid- 

 ium, with which it was formerly united. It differs 

 principally in having the lateral sepals entirely united, 

 forming a single segment resembling the dorsal sepal 

 in shape and size, the labellum scarcely larger than 

 the petals and resembling them in shape. 



Candida, Reichb. f . The only species is a small plant 

 with narrow, compressed pseudobulbs, each with a sin- 

 gle slender leaf, 6-12 in. long: fls. few, small, white, 

 in a slender raceme ; sepals, petals and labellum ob- 

 long, acute, differing but little in size and shape. Gua,te- 

 maja. B.M. 5546. G. C. 1865:793; II. 20:233 (as On- 

 cidium candidiim).~M.ay be easily grown in a temper- 

 ate house. Blooms in summer, the fls. lasting a long 

 time- HEINRICH HASSELBKING. 



PAMPAS GRASS. See Gynerium. 



PAN AX (old Greek name, meaning all -healing). 

 Araliacece. Thirty to 40 trees or shrubs, mostly of the 

 tropics of Asia, Africa, Australia and the Pacific islands, 

 as defined by Bentham & Hooker ( including Nothopanax ) , 

 some of which are grown in warmhouses for their inter- 

 esting habit and foliage. The genus is confused in gar- 

 dens with Aralia,Acanthopanax,Fatsia,Eleutherococcus, 

 Polyscias, and others. From the Aralia group it is dis- 

 tinguished by having the petals valvate (applied edge- 

 to-edge) in the bud. From Polyscias, Pseudopanax and 

 Eleutherococcus it is known by its gynoecium (or pis- 

 tils) being usually in 2's, rather than in 5's or higher 

 numbers. From Fatsia it is distinguished by having 

 the pedicel articulated beneath the flower. See Fatsia 

 for another discussion of relationships. Panax has a 

 calyx with entire or 5-toothed margin, 5 valvate petals, 



5 stamens with oblong or ovate anthers, usually 2-lo- 

 culed ovary which ripens into a drupe-like compressed 

 fruit, and with mostly compound, often much-divided 

 leaves: fls. small, sometimes polygamous, in umbels, 

 heads, racemes or panicles. The Panaxes are to be 

 grown in the warmhouse, where they should have the 

 treatment given tropical Aralias (see p. 87). 



As defined by others, the genus Panax includes only 

 7 or 8 herbaceous species, natives of the temperate re- 

 gions of North America and Asia, while the woody spe- 

 cies are referred mostly to Polyscias and Nothopanax; 

 the species of the Polyscias have, according to Harms, 

 pinnate leaves, and those of the other have digitate 

 or simple leaves. As thus understood, the genus Panax 

 includes the ginseng, P. quinquefolium, for which see 

 Ginseng. The dwarf ginseng or ground-nut of the 

 northern states is P. tri folium. It is not in the trade. 

 These two plants are often described in the genus 

 Aralia as A. quinquefolia and A. tri folia. 



fruticdsum, Linn. (Nothopanax fruticdsum, Miq. 

 Polyscias fruticosa, Harms). Shrub 3-6 ft. in cult., 

 with pinnately compound Ivs., the Ifts. stalked, ovate- 

 oblong, acuminate, coarsely serrate, the ultimate ones 

 incised, 3-lobed: fls. in paniculate umbels. Java, etc. 

 Prized for its fern-like foliage, but known mostly in its 

 cultivated varieties. 



Var. Victdriee (P. Victorice, Hort.). Fig. 1628. A 

 compact form which constantly sends up new stalks: 

 foliage recurving, cut, curled and tasselled. light green, 

 with white - variegated 

 margins. G.C. II. 19: 

 405. I.H. 31:521? An 

 excellent table plant. 

 Through inadvertence, 

 Fig. 1628 was used in 

 the place of Aralia 

 Guilfoylei, p. 87,1st ed. 



Var. laciniatum (P. 

 laciniatum, Hort.). 

 Lvs. twice - pinnate, 

 drooping, about as 

 broad as long, tinted 

 with olive-brown, the 

 leaflets and divisions 

 narrow. Very grace- 

 ful. 



Var. exc61sum (P. 

 excelsum, Hort.?). 

 Lvs. very finely cut and fern-like, margined with white. 



Var. plumatum (P. plumdtum, Hort.). More finely 

 cut than var. laciniatum, and differing from var. excel- 

 sum in having no white on the foliage. 



ISpidum, Bull. Compact: Ivs. biternately divided, 

 the end division largest; pinnules or ultimate leaflets 

 obliquely obovate, the central one in each case small 

 (sometimes almost rudimentary) and more or less cov- 

 ered by its two lateral ones, the margins spiny-toothed 

 and cut. Brazil. Recent. 



nitidum, Bull. Compact : Ivs. roundish obovate, 

 toothed and somewhat spiny, sometimes with deep in- 

 cisions. Brazil. Recent. 



aureum, Sander. "A distinct elegant and highly at- 

 tractive Panax, the whole leafage being suffused with a 

 delicate golden green variegation. The habit is similar 

 to that of P. Victorice, quite as compact and bushy, but 

 not heavy in the slightest sense of the word. Individ- 

 ually the leaves are small, the edges finely serrated, 

 while near the margins are several splashes of clear 

 green." Sander. 



Balfourii, Sander. "A decided acquisition for all dec- 

 orative requirements, strikingly and profusely varie- 

 gated. Its luxuriant pinnate leafage renders its deep 

 green and creamy white coloring the more attractive. 

 Each of the pinnae forming the leaf is orbicular in 

 outline and deeply serrated, of a rich ivy green, abun- 

 dantly splashed with creamy white, the edges of the 

 leaves being entirely white. The stems are bronze- 

 green, specked with gray. The habit is compact and 

 bushy, well feathered from base to apex with foliage. 

 Intro'duced by us through our collector, Micholitz, from 

 New Caledonia."
