Revisions of Ceylon Natural Orders. 



[A. Engler : Das Pflauzenreich. Leipzig, 1900 (in progress.)] 



§ 1. Musacece, by K. Schumann. The only Ceylon species of 

 Musa is referred, as in Trimen's Flora, to M. paradisiaca, L., but 

 bo subspecies 4, troglodytarum, L., Bak. Trimen, however 

 remarks that he has seen nothing here with an erect inflorescence. 



§ 2. Typhacece, by P. Graebner. The only Ceylon species, 

 Typha javanica, Schnizl., is, as hinted by Hooker, placed as a sub- 

 species under T. nngiistifolia, L. 



§ 3. Pandanacece, by O. Warburg. Freycinetia Walkeri, 

 Solms, F. pycnophylla, Solms, and Pandanus zeylanicus, Solms, 

 are retained. The other species of Pandanus given for Ceylon by 

 Trimen {odoratissimus L. f. and foetidus (var) Roxb., the latter 

 given as P. affinis, S. Kurz) are not mentioned as occurring in 

 Ceylon. The whole account appears to have been made up at 

 Buitenzorg and Berlin, and ignores the contents of the Peradeniya 

 and Kew herbaria. 



§ 4. Monimiacece, by J. Perkins and E. Gilg. Hortonin ovah- 

 folia, Wight, given as a variety of H. floribunda by Trimen, is 

 raised to specific rank, as well as H. angustifoUa, Trim., and H. 

 floribunda, Wight. 



§ 5. Rafflesiacecp. and Hydnoracem, by H. Graf zu Solms-Lau- 

 bach. None in Ceylon. 



§6. Symplocacece, by A. Brand. The genus Symplocos, placed 

 in Styraceae by Trimen, is here given a separate family. To deal 

 with the species in Trimen's order : (1) S. spicata, Roxb., is made 

 to include (5) S. versicolor. Clarke ; (2) S. obtusa. Wall, is said not 

 to occur in Ceylon, and the plant thus described (C. P. 

 626, Gardner, 538, in Hb. Brussels, Walker, in Hb. Berlin) is 

 described as a new species, S. furcata, Brand. The variety /3. 

 major, Thw., is described as a new species, S. major. Brand. The 

 var. y obovata, Thw., was not seen, but is suspected of being a new 

 species, and the var. o. , cucullata. Thw. , is made into a new species, 

 £. cucullata, Brand ; (3) S.lmta, Thw. , and (4)6*. bractealis, Thw., are. 

 maintained ; (5) S. versicolor, Clarke, is sunk in S. spicata ; (6) 



* The articles which appear under this head are written primarily 

 for the Ceylon constituency of this journal, and deal chiefly with 

 advances in Science which are of immediate local interest.
