Palmae. 

 Juania australis (Mart.) Drude. Affinities undoubtedly trop. Andean. Included 

 in the Iriarteae by Dkl DE, but perhaps nearer to the Morenieae, or possibly 

 regarded as type of a separate subtribe. HUTCIIINSON brought Juaiiia next to 

 Ctroxylo}!, following Bextiiam and HooKER, Croizat (7/) remodelled Morenieae, 

 including Jutuiia and the Mascarene IlyopJiorhe, otherwise linked with Chamae- 

 doreae. 



Bromeliaceae. 

 Ilcsperogreigia Berteroi Skottsb. 2 or perhaps more sp. Subtrop. Andean, related 

 to (ireigia («S sp., Costa Rica, Venez.-S. Chile). LOOSER called Hesperogreigia 

 monotypical, because my {)ai)er (2^0) had escaped him; if not, he would not have 

 written "^'Ouiza dc la afinidad de Greigia.^" [ijo. 291). Inspired by L. B. SMITH 

 he sup{)ressed I fispcrognigia in an appendix to his paper (p. 299), an attitude 

 I cannot take. The two genera differ very much.^
