We subjoin the characters of the new species. 



1. /. leucanthus (Royle), culmo bifolio tereti, foliis margine involutis 

 filiformibus culmum subsequantibus, capitulo terminali solitario 6 — 10- 

 floro, involucro 5-phyllo glumaceo floribus longiore, sepalis acutius- 

 culis, antheris acutis filamentis duplo longioribus, ovario incluso, stig- 

 matibus stylo ter brevioribus. 



This species is nearly allied to /. triglumis.

 canaliculatis, capitulo terminali 3 — 5-floro involucro 3-phyllo acuto 

 breviore, sepalis obtusis, antheris filamentorum fere longitudine, capsula 

 acuminata perianthio longiore, 



3. /. memhranaceus (Royle), culmo tereti subdiphyllo, foliis subfiliformi- 

 bus obtusis, capitulo terminali solitario 4 — 8-floro bractea communi 

 membranacea breviore, sepalis obtusis capsula acuta longioribus, stami- 

 nibus inclusis, antheris filamentis dilatatis ter brevioribus. 



4. J. concinnus (Don. Prodr. Fl. Nepal, p. 44), culmo tereti subdiphyllo, 

 foliis planiusculis obtusis, capitulis 3 — 6-floris corymbosis, bractea 

 communi elongata foliacea, sepalis acutis capsula acuta longioribus, 

 staminibus longe exsertis, antheris filamentis simplicibus 6-pl6 brevi- 

 oribus. 



5. /. indicus, triandrus ; capitulis multifloris squarrosis trichotome cy-

 of OphrydecB." By John Lindley, Ph. D., F.R. and L.S., Prof. Bot. 

 University College. 



The object of the author in this paper was to show that salep, the 

 prepared roots of certain Ophrydece, is not a substance consisting 

 principally of starch, as is the common opinion among writers of the 

 present day, but is composed of a bassorine-like matter, organized 

 in a peculiar manner. 



After stating the opinions of recent authorities, the author gives 

 the results of his own microscopical examination of the tissue of re- 

 cent and prepared roots, by which it appears that the tubercles of 

 Ophryde<E universally contain large cartilaginous nodules of a muci-
