Koehne, and its sub-species uliginosa f. diffusa, and melito- 

 glossa &. mino7-, expansa, and densifiora are given for Cojion, 

 but no specimens are cited. Ammania baccifera remains 

 imchanged, subsp. viridisheing cited (again witliout specimen) 

 for Ceylon. Ammania cordata Wight and Arn. and At7im. 

 lanceolata Heyne become Nessea brevipes Koehne and Nescea 

 lanceolata var. stricta (Thw. 2796) respectively. Rotala 

 rotundifolia (Roxb.) Koehne and Ammania midtiflora Roxb. 

 var. parviflora are additions to the Ceylon Flora, for which no 

 authority is given unless Flora British India. 



Woodfordia floribunda Salis. becomes W. fruticosa (L.) 

 S. Kurz., Lawsonia alba Linn, becomes L, inermis L., 

 Lagerstroemia flos-reginse Retz becomes Lag. speciosa L., 

 Pemphis acidula remains unchanged. Nessea triflora (L.) 

 Kunth. is cited for Ceylon, without mention of the fact that 

 it is generallj^ regarded as an introduction. 



18 Heft. Taxacese by R. Pilger. No species in Cej'lon. 



19 Heft. Betulacese by H. Winkler. No species in 

 Ceylon. 



20 Heft. Zingiberacese by K. Schumann. Alterations in 

 this family are comparatively few. Amomum floribundum., 

 A. involucratutn, and A. nemorale are attributed to " (Thw.) 

 Benth.," instead of to Trimen, on the evidence of Genera 

 Plant., III. A var. induta is described of A. acuminatum 

 Thw., with the note that the tj^e and variety are fovmd in 

 the same Thwaites' number, but are perhaps different species, 

 the specimens being insufficient for decision. A. ftUviceps 

 and A. ciliatmn apj^ear as Pliseomeria fulviceps (Thw.) 

 Schum. and Phseomeria ciliata (Bak.) Schum. respcctivoh'. 

 Amx)mum rvfescens Trim, becomes Alpinia rufescens (Thw.) 

 Schvim. In A. graminifolium, " Lingheradja" is written for 

 " Singhe Raja." Alpinia nutans Rose, is changed to A. 

 speciosa (Wendl.) Schum., but the Ceylon var. sericea Moon 

 is not mentioned. The Ceylon form of Coatus speciosus is 

 attributed to var. lasiocalyx Schum. Globba bulbifcra Roxb. 

 is said to be probably an escape in Ceylon, and Hexlychiinn 

 coccineum doubtfully native, wliile Amomum echinatum 

 presumablj'^ occurs in Ceylon ; these statements are due to 

 neglect of Ceylon records and specimens. The former name 

 Elettaria major Smith is adopted for Ehttaria cardamonuim 

 Maton var. major. A new species of Cyphostigma, C. pedicel- 

 latum Schum. (Thwaites 2736a) is described; it is mixed 

 with the type, but differs in its much broader solitary 

 leaves, broader but simpler inflorescence, and pcdicollato 

 flowers. 



21 Heft. Aracese — Pothoidese by A. Engler. Pothns 

 ceylanicus Engl. n. sp. is described from Herb. Peradeniya 

 and Herb. Berlin ; the remaining Ceylon species are un- 

 changed. The Cej^lon form of Acorus calamus is assigned to 

 var. b. verus.
