PANDANUS 



PANICULARIA 



advertised in Arner., but for the popular variegated 

 form, see No. 2. 



15. Vandermeeschii, Balf. f. Lvs. stiff, suberect, 

 2%-3 ft. long, l%-2 in. broad, very glaucous; margins 

 red and thickened; spines strong, red; midrib red, 

 prominent, spiny. Attains 20 ft. in Mascarenes. G.C. 

 III. 18:237. Taplin says it is stouter and usually more 

 upright than P. Veitchii; its Ivs. are dark green and the 

 plant does not produce suckers. The spelling Vander- 

 meerschii is probably incorrect. 



ANOTHER VIEW OF PANDANUS. 



In the third edition of Vilmorin's Blumengartnerei, 

 Voss gives a very different treatment of Pandanus. It 

 has every evidence of being based upon living plants in 

 German conservatories. A portion of it is here trans- 

 lated a'nd rearranged. Voss makes the species-endings 

 feminine because of the old Latin rule about the gender 

 of trees.

A. Young plants with imbranched stems. 

 B. Upper side of Ivs. flat on each half. 



1. utilis, Linn. (P. odoratissima, Jacq.). Margin of 

 Ivs. purplish red, strongly spiny: lower side of Ivs. with 

 a keel. Var. Madagascariensis, Van Houtte (P. Van- 

 dermeeschii, Balf. ) . Lvs. thickly white -powdered at the 

 base. P. Forsteri, Moore, from Lord Howe's Island : Ivs. 

 light green and shining above, bluish green beneath; 

 spines yellowish green. 



BB. Upper side of Ivs. more or less keeled on each half. 



2. furcata, Roxb. (P. caricdsa, Hort. ) . A fast grower; 

 large specimens occasionally flower in German conser- 

 vatories and then branch. Lvs. light green; spines 

 lighter, marginal ones erect, those of the keel below 

 recurved. 



3. Candelabrum, Beauv. In this and No. 2 the stems 

 are thin and the aerial roots very thick. Lvs. blue-green ; 



1632. Young specimen of Pandanus utilis, 

 (Rather narrower-lvd. than the type). 



spines light colored, tipped brown. The inference is 

 that this species is distinguished from No. 2 by the 

 spines of the lower keel not being recurved. 



AA. Young plants with scarcely any stem. 

 4. reflexa, de Vriese. Lvs. strongly reflexed; spines 

 on margin and 'lower keel strong; no keels above. P. 

 ornata, Lam., lacks the spines on the lower keel, but is 

 otherwise the same. 



1633. Pandanus utilis. 



An old Screw Pine in the tropics. 

 The Garden.) 



(Adapted from 



AAA. Young plants freely branched from the ground. 

 B. Spines absent or only a few at the apex of Ivs. 



5. laevis, Roxb. (P. odoratissima, Noronha). (Not 

 adv. in America, but inserted because of its synonym 

 and the interest attaching to a spineless Pandanus.) 



BB. Spines present and sharp. 

 c. Upper side of Ivs. flat on each half. 



6. pygmaea, Thouars (P. graminifdlia, Hort. ) . Dwarf, 

 and densely bushy, with many aerial roots: Ivs. dark 

 green; marginal spines whitish. 



CC. Upper side of Ivs. more or less keeled on each half. 



7. nitida, Kurz^. (P. graminifdlia, Hort.). Shrubby, 

 attaining 8 ft. Lvs. remarkably shiny on both sides ; the 

 lower keel lacks spines. 



8. Javanica, Hort. Bushy: Ivs. dark green above, 

 only slightly shining, beautifully striped with white; 

 marginal spines straight; spines of the lower keel bent 

 back. P. Veitchii, Lem. Lvs. shining on both sides, 

 striped yellowish white, sometimes all yellowish white; 

 spines not half as long as in P. Javanica. ^ ]\j 



PANICULARIA (Latin name referring to the pani- 

 cled spikelets). Glyceria of the trade. Graminece. A 

 large genus of swamp grasses inhabiting all parts of 

 the temperate zone, and characterized by ample pani- 

 cles, many-fld. spikelets with only the 2 lower glumes 

 empty; the others firm in texture, obtuse, strongly 5-7- 

 nerved, rounded on the back, and without cobwebby 

 hairs; styles present. Only the following are in the 

 American trade : 



Americana, MacM. ( Glyceria grdndis,Wa,ts., also Hort. 

 Glyceria aq^ldtica, Amer. authors). REED MEADOW- 

 GRASS. Tall, erect and stout (3-5 ft. high), glabrous: 

 Ivs. large and broad (3-8 lines broad), spreading: pani- 

 cle very large (8-15 in. long), mostly dark brown, its
