apice recte truncata ut in ala longe spinosa, spinis ut in folio sed magis confertis. 



Folia floralia caulinis simillima. Andrcecia in caule tcrininalia, longe spicata, 



spicis ad 2 vel 3 subfasciculatis erectis; bracteae ad 1<> ju^ie, e hasi longe saccata 



parum recurvo-patulae, apice truncate et paucidenticulatae.

 In JPlagiochila superba, Wahlenb., the leaf-cells are much larger, the spines very stout, 

 very much longer and less numerous. Lindenberg says (Monogr. Flag. p. 80) that Sieber 

 had given him this species as coming from Australia ; but this is a mistake of Sieber, 

 who had not marked his packets and did not know on his return whence he had 

 procured the plants ; many errors of the same kind have been previously pointed 

 out by me.
