314 Select Plants for Industrial Culture and 



resin : Imbricaria coriacea A. de Candolle ; Mimusops Eleiigi, L. ; 

 M. Manilkara, G. Don ; Sideroxylon attenuatum, D. C., Illippe 

 (Bassia) sericea, Blume ; Payenia macrophylla, P. Leeri (which 

 affords the Sundek-Gutta in brackish coast-lands, as shown by 

 Dr. Trimen) and P. Maingayi, Cl. ; Palaquium obovatum, P. 

 polyanthemnm, P. Krantzianum, Burck ; Cocosmanthus macro- 

 phyllus, Hassk., all from, tropical Asia ; Chrysophyllum. Africanum, 

 A. de Candolle, from tropical Africa ; Achras sapota, L., Mimusops 

 globosa, Gaertner, from Central America; but many of these at 

 often cool elevations. Possibly other sapotaceous trees, including 

 some Australian, could be worked for Gutta-Percha. Of this 

 article 62,000 cwt. were introduced into Great Britain in 1884, 

 valued at 462,000, in 1889 the import amounted to 48,000 cwt., 

 worth 575,000, of which quantity this Palaquium must have 

 supplied a large proportion. Pierre, after the indications of 

 Bentham, adopts the generic name Palaquium, and adds as Gutta- 

 Percha yielding : Palaquium Malaccense, P. Oxleyanum, P. for- 

 mosum, P. princeps and P. Borneense, all previously undescribed 

 species, either from Malacca or Sumatra or Borneo (see Bulletin 

 mens. de la Soc. Lin. de Paris, Juin, 1885). Dr. Burck admits 

 among iSunda-Island Gutta-Percha trees as really valuable only 

 Palaquium oblongifolium (the most frequent and the best), P. 

 Borneense, P. Treubei, the original P. Gutta being as a native plant 

 almost annihilated. P. ellipticum (Bassia elliptica, Dalzell) 

 ascends to the almost temperate elevations of 4000 feet, and is 

 tapped for Pala, a substance allied to Gutta Percha [General 

 Cullen]. 



Paliurus ramosissimus, Poiret. (P. AuUetia, Schultes.) 



China and Japan. A thorny tree, which could be utilised for 

 hedging. 



Paliurus Spina Christ!, Miller. (P. aculeatus, Lambert.) 



The Christ-Thorn. From the Mediterranean Sea to Nepal. A 

 deciduous bush or finally tree, which can be trimmed into hedges. 



Pandanus furcatus, Roxburgh. 



This Screw-Pine occurs in India, up to heights of 4,000 feet, 

 according to Dr. S. Kurz ; hence it will be likely to bear a 

 temperate clime, and give a stately plant for scenic group-planting. 

 P. pedunculatus, B. Br., occurs in East-Australia as far south as 

 32, and an allied tall species (P. Forsteri, Moore and Mueller) 

 luxuriates in Howe's Island. 



Panicum ag-rostoides, Muehlenberg. 



North-America. One of the hardiest species, bearing the winter- 

 cold of New York. Can be utilised for muddy banks and undrained 

 marshy meadows. Easily disseminated, forming large tall clumps, 

 flowering as well from the joints as top ; yields abundance of hay, 

 but must be cut while young [Dr. Yasey].
