462 CLXIII. PALME^E. (Beccari & Hook, f.) [Dcemonorops. 



72. C. XiObbianuSj Becc. mss. ; leaflets equidistant linear-lanceolate 

 caudate-acuminate membranous, clothed beneath with an appressed white 

 substance (as if coated with lime), costae 3 all naked or with a very few 

 bristles beneath, spadix slender and rachis and upper spathes aculeate, male 

 spikes crowded very short and broad with densely crowded distichous large 

 flowers. 



SINGAPORE, Lolb, G. Panti (210 Herb. Calcutta). 



A small palm, stem 18 in., 6-8 in. diam. Leaves 5-6 fl. ; leaflets 12-14 by 

 1-li in., rachis of the portion seen unarmed. Spatkes (upper?) with a short keeled 

 sheath and acuminate limb, armed with straight slender spines ^~\ in. long on the 

 sides and keel ; branch of male spadix 3 in. long, oblong; spathellules most densely 

 imbricate, in. diam. Male fi. nearly \ in. ; calyx cupular, with broad triangular 

 lobes, not pedicelliform ; petals twice as long, the lobes narrowly lanceolate. I have 

 seen only the branch of a male spadix and a fragment of a leaf with 7 leaflets, both 

 from G. Panti. J.D.H. 



DOUBTFUL SPECIES. 



C. EXTENSUS, Hoxb. Fl. Ind. iii. 777. Probably 0. palustris. 



C. HUMILIS, Eoxb. I. c. 773, is possibly 51, latifolius. 



C. METZIANUS, Schlecht. in Linncea, xxvi. 727 from Canara (?= C. rivalis, Thw.). 



C. PENICILLATUS, Hoxb. Fl, Ind. iii. 781. If for 30-40 pair of segments in 

 Roxburgh's description, 3-1 be substituted, this might apply to C. javensis, Bl. 



C. POLYGAMUS, Roxb. Fl. Ind. iii. 780 ; Mart. Hist. Nat. Palm. 210 ; Griff, in 

 Calc. Journ. Nat. Hist. v. 48 j Palms Bri f . Ind. 58, is not recogniable. 



24. D2ETOONGROPS, Blume. 



Characters of Calamus, but outer sheaths or spathes cymbiform, decidu- 

 ous, at first enclosing the inner ; flowers often more pedicellate. Species 

 about 80. Distrib. as of Calamus. 



Dcemnnorops differs so little from Calamus, and by sectional rather than generic 

 characters according to Griffith, Kurz and others, that it was united with the latter 

 in the " Genera Plantarum." As, however, Beccari, the latest and best authority 

 on Indian Palms, keeps them apart, and as the elaboration of .the species no less than 

 their nomenclature in this work owes so much to him, I think it right to follow his 

 lead. The difficulty of separating them in practice, working upon herbarium speci- 

 mens, is show n by the synonymy of various species of both. 



Sect. I. Cymbospathae. Spathes cymbiform, beaked, two outer 

 completely enveloping the inner. Male spadix fusiform before flowering. 



* Stem scandent. 



1. D. Jenkinsianus, Mart. Hist. Nat. Palm. iii. 327 ; leaflets equi- 

 distant linear finely acuminate, costse 3 all sparsely setose above with verv 

 long bristles, the central only beneath, margins setulose, petiole rachis and 

 flagellum with many marginal and dorsal hooked spines or 3-5-fid claws, 

 sheath armed with very long flat deflexed and shorter more slender spines, 

 spadix elongate decompound, outer spathe flattish 2-keeled armed with flat 

 spines narrowed into a long ppinescent beak, fruiting calyx nearly flat, fruit 

 globose apiculate. Walp. Ann. iii. 475 ; v. 827. D. nutantiflorus, Mart. 

 I.e. 326 ; Walp. l.l. c.c. 474, 827. Calamus Jenkinsianus, Griff, in Calc.
