C. Arnottiana, 



A specimen of this species was preserved in the her- 

 barium of Nees von Esenbeck, and Drejer^^ described and 

 figured it : 



''Spicis 10 pedunculatis, pendulis, densifloris, cylindricis, 

 obtusis: superioribus geminatis, approximatis, duabus infimis soli- 

 tariis, distantibus; bracteis inf erioribus late foliaceis, culmum 

 longe superantibus, evaginatis auriculatis ; squamis ovato-lanceo- 

 latis acuminato-subcuspidatis ; perigyniis (immaturis) ellipticis, 

 laevibus; rostro breviusculo apice hyalino; stigmatibus binis. 

 Habitat in Ceylona, ad altitudinem 6000 pedum Arnott. ' ' 



Regarding its affinity Drejer writes : 



''Quamquam ex specimine unico, florente, radice, foliis, cul- 

 mique inf eriore parte carente, certum judicium f erre non possum, 

 tamen non dubito, quin affinitas huic specie! sit cum Caricihus 

 aeorastachyis, minus tamen cum C. glaiicescente, quam cum dis- 

 tigmaticis C. salina Whlb., Lynghyei Hernem., macrochaeta C. A. 

 Mey, reliquique." 



Kukenthal (1. c. p. 350) describes the mature perigynia 

 and squamae: 



"Utriculi squamis breviores latiores adpressi membranacei 

 subobovati compressi 2% mm. longi fusci superne granulosi 

 enervii basi cuneati marginati, rostro brevi integro apiculati. 

 Squamae 2 lanceolatae acuminato-aristae (arista laevis) atro- 

 fuscae dorso viridi trinerves.'' 



The TernaricB constitute the last section of the Aeoras- 

 tachycB with two stigmata. We have seen the gradual 

 evolution of this part of the grex from the Salince with 

 the terminal spike being staminate, and the pistillate lat- 

 eral and single in the axils of the bracts, to the Phacotce
