I have found some difficulty in placing this form, which is 

 evidently fully developed. In general outline it is certainly 

 nearest to Eu. verrucosum /3 Wallichianum Turn., Alg. E. Ind. 

 T.ll, f.9, but it is ruled out of any connection with Eu. verrucosum 

 by its smooth membrane. In comparing Nordstedt's figures, I.e. 

 T.l, it seems apparent that f.17 (inermius) much more resembles 

 f. 15 [Eu. quadratum /3 javanicum) than it does f. 16, or Eu. 

 spinulosum Delp. The shape of the polar lobes is quite different, 

 and the general character of the markings much coarser than in 

 Delponte's plant or in subsp. africanum. There is nothing in the 

 size or the end-view to prevent inermius from being regarded as 

 a subsp. of Eu. quadratum /3 javanicum, and this is made more 

 probable by the fact that both are Javanese plants from the same 

 gathering — "Java, in Utricularia fiexuosa (herb. Blume)" in 

 each case, I.e. p.9-10. 



Since writing the above, in a sample from the same source I 

 have come across a single clean semicell belonging to this species, 

 and intermediate in character between (3 javanicum and subsp. 

 inermius. This I will name 



Eu. quadratum Nord. var. intermedium, n.var. 



Semicellulse profunde ut in subsp. inermius incisae, lobis autem 

 in sciagraphia (3 javanico congruentibus. 



Long, semicell 42; lat. 72; lat. lob. pol. 28; crass. 42/a; basis 

 lob. pol. 25/x supra isthmum; lat. ad constrict, supra lob. basal. 

 45,*. 



The life-history of this interesting plant seems to run thus : — 

 (1) Eu. quadratum Nord.; (2) (3 javanicum Nord.; (3) var, inter- 

 medium mihi; (4) subsp. inermius (Nord.) ; (5) var. ornatum
