100 BOTANICAL NOTES. 



Celebes, and by Warburg, Hollrung and others' in New Guinea. 

 In his arrangement he adheres to the old classification including 

 Hornstedtia, Plagiostachys, etc., under Amomwn, and so on. One 

 new genus he describes under the name Haplochorema seems to be 

 a true Koempferia with creeping rhizomes. It occurs in Borneo, 

 four kinds being described from Sarawak. One might describe 

 it as a Koempferia adapted for jungle life. Hedychium microchi- 

 lum described from Java in my paper in the last Journal, appears 

 as Brachy chilus Uorsfieldii Peters. It was originally described 

 under the name of Hedychium Horsfieldii in Hooker's Kew 

 Miscellany, and also by Peters in a Copenhagen Botanical Jour- 

 nal, both works difficult to procure. The whole habit of the 

 plant is so much that of Hedychium, that I think it would be bet- 

 ter to keep it in that genus. A good figure of what is evidently 

 the common Cost us globosus Bl is given under the name of C. 

 acanthocephalus n. sp. It was collected in West Sumatra by 

 Beccari. The plant is evidently widely distributed. The whole 

 monograph is interesting from a geographical point of view, for 

 though of course one may be sure that many more of these 

 plants will be found in the Eastern islands, it gives sufficiently 

 clear evidence of the change in the flora as we go further east. 

 Thus one notices that the Globbas, so abundant here, disappear 

 to a large extent, few occurring in Borneo, fewer in Java, and 

 only one (excluding G. marantina probably introduced) further 

 east in the Philippines. Gastrochilus, except the cultivated G. 

 panduratus, does not occur in the list ; but probably this is due 

 to the difficulty of getting the flowers in wild plants. Zingiber 

 also disappears rapidly towards the East, but one kind has been 

 met with in New Guinea. Tapeinocheilus appears to be abundant 

 in the Papuan region, fourteen species of these grand plants 

 being catalogued, extending from Amboina to New Guinea. 



Alpinia rosella Ridl. Since publishing this species (Journal 

 32. p. 164) I have found a figure and description of a plant col- 

 lected in British North Borneo by Burbidge and published under 

 the name Alpinia Fraseriana Oliver, in the Icones Plantarum 

 vol. vi. pi. 1567, which agrees closely with A. rosella, and is I 

 think the same species. Ialso note some misprints in my de- 

 scription on p. 165, in line 2 absent should be about, and in line 10 

 the words should run " Seeds 3 about £ inch through.
