PAN AX 



The above comprise all the Panaxes known to have been of- 

 fered in the American trade, but there are many novelties in 

 Old World collections, which may appear here at any time. 

 The garden plants are often named before they have bloomed, 

 and are therefore sometimes referred to the wrong genus. 

 Some of the names are here given: P. crispittum, Bull. Dwarf: 

 Ivs. triangular, pinnate, the Ifts. deeply incised and toothed, 

 the lateral ones overlapping. Brazil. P. Deleauanum, Hort., 

 is properly P. fruticosum, var. Deleauanum, N. E. Brown. A 

 remarkable variation with digitate Ivs., the divisions ternate 

 or 2- ternate, the ultimate segments variable, but cuneate at 

 base, toothed and cut and white-toothed. Polynesia, I.H. 

 30:492. Known also as Aralia Deleauana. P. diffitsum, Bull. 

 Form of P. fruticosum, with bright green, crisped Ifts., which 

 are linear-oblong and spiny - toothed. Polynesia. P. dissec- 

 tum, Bull. Erect, branching, the 2-pinnate Ivs. drooping, the 

 Ifts. cuneate-obovate and toothed and often 2-lobed. P. dumb- 

 sum, Bull. Short-stemmed: Ivs. roundish ovate, pinnately 

 divided, the variable ultimate divisions spine-toothed. P. fis- 

 sum. Bull. Stem marked with pallid spots: Ivs. 3-pinnate, the 

 Ifts. linear-lanceolate and whitish toothed. Polynesia. P. 

 Mastersidiiitm, Sander. Of climbing habit, with long-stalked 

 drooping pinnate Ivs. about 3 ft. long, the petiole greenish, 

 tinged with pink and marked with white, the Ifts. oblong-lan- 

 ceolate and toothed. Solomon islands. G.C. III. 23:242. P. 

 multifidum, Hort., is properly P. fruticosum, var. multifidum, 

 N. E. Brown. Compact plant, with 3-pinnatisect Ivs. and lin- 

 ear^or linear-lanceolate segments % i n - or l ess long, with bris- 

 tly teeth. P. Murray i, Muell. (Aralia splendidissima, Hort.). 

 Tree in its native place, with drooping, shining green pinnate 

 Ivs. 3-4 ft. long, and many oblong-lanceolate Ifts. 3-6 in. long: 

 umbels of brownish fls. in long, terminal panicles. S. Sea 

 islands, Austral. B.M. 6798. P. orndtum, Bull. Lvs. long, 

 pinnate, the Ifts. narrow-lanceolate and deeply blunt-toothed. 

 Brazil. P. sessiliflorum, Rupr. & Max., is described in Acan- 

 thopanax, its proper genus. L. H B 



PANCRATIUM (Latin, all-power fill; referring to sup- 

 posed medicinal value). AmarylliddLcece. Pancratiums 

 and Hyuienocallis, sometimes called Spider Lilies or 

 Spirit Lilies, form a beautiful group of bulbs, hardy or 

 tender, some blooming in winter, others in summer, 

 and all characterized by the singular and beautiful floral 

 structure known as a staminal cup and pictured in Vol. 

 II at page 788. This cup is white and has the texture of 

 petals. It is fringed or toothed in a great variety of 

 ways. The filaments growing out of the cup are long 

 or short. The perianth segments are generally long, 

 slender and gracefully recurved. Thus many fanciful 

 variations of the Spider Lily type are produced. 



The names of these charming plants have been 

 shifted back and forth between Pancratiums and Hy- 

 menocallis until horticulturists have come to despair. 

 The latest monographer of the Amaryllis family (J. G. 

 Baker, in Handbook of the Amaryllidese, 1888), distin- 

 guishes the two genera as follows: Pancratium has 

 many ovules in a cell and the seeds are black and 

 angled by pressure; Hymenocallis has few ovules in a 

 cell, and the seeds are usually solitary, large, and with 

 a thick, green, spongy coat. Pancratium is an Old 

 World genus : Hymenocallis is a New World genus, H. 

 Senegambica, an African species, being an exception. 



For generic description and culture, see Hymenocallis . 

 Also notes by Miss L. Greenlee in Vick's Mag. 20:181, 

 where, however, the picture labeled P. ornatum prob- 

 ably represents P. or/w, which is Hymenocallis ovata.

PANDANUS (Latinized Malayan name). Pandanacece. 

 SCREW PINE. Screw Pines are tropical plants often at- 

 taining the size of trees, and remarkable for their stilt- 

 like aerial roots, and the perfect spiral arrangement of 

 their long, sword-shaped Ivs. Their general appearance 

 is singular. See Fig. 1633. They hold aloft a few 

 long, scarred, naked branches, each one of which is 

 crowned by a tuft of Ivs. The aerial roots gradually 

 lift the trunks out of the ground, but they doubtless 

 anchor the trees also. They are, however, difficult 

 organs to explain. Pandanuses are also remarkable for 

 their spines, which are rather small but very numer- 

 ous, all the same size and arranged at regular intervals 

 along the whole of each gracefully recurved sword- 

 shaped leaf a perfect expression of formal linear 

 beauty. 



Two species of Pandanus are of the first importance, 

 P. Veitchii and P. utilis, the former variegated, the 

 latter not. ( See Figs. 1630-32. ) Young plants of these are 

 amongst the most popular of all foliage plants for home 

 decoration. They are especially suited for fern pans 

 and table decoration. They are grown to a very large 

 extent by wholesale florists and palm specialists. Every 

 conservatory has them, and occasionally P. utili* is
