Probably the nearest relative of this species . is Pitcairnia ctenophylla L. B. 

 Smith, but that has much narrower leaf-blades which are not at all narrowed at 

 base, small scape-bracts much shorter than the internodes, and floral bracts much 

 shorter than the pedicels. 



Pitcairnia epiphytica L. B. Smith, sp. nov. Fig. 20.

 dimorphis, alteris ad flagellas oarvas flexuosas gracillimas laxe serrulatas re- 

 ductis, alteris longe petiolatis, lineari-lanceolatis, utrinque acuminatis, 8 dm 

 longis, 35 mm latis, supra glabris, subtus dense adpresseque albo-lepidotis, ad 

 apicem versus serrulatis, petiolis laxissime serratis; scapo erecto, flexuoso, 

 albo-flocculoso; scapi bracteis internodia superantibus, lanceolatis, ad apicem 

 versus longe acuminatis serrulatisque, viridibus; inflorescentia simplicissima,

TYPE: epiphytic, along uppermost Rio Yatua above mouth of Rio Yacibo at 

 100-140 m alt., Amazonas, Venezuela, January 30-31, 1954, B. Maguire, J. J. 

 Wurdack & G. S. Bunting 37442. 



The only specimen of this species is too young to show the appropriate char- 

 acters but it appears related to species with an indehiscent fruit such as Pit- 

 cairnia leprieurii Baker and P. uaupensis Baker. It differs from the former in its 

 serrate scape-bracts and lower floral bracts and from the latter in its much 

 broader leaf-blades and large lower floral bracts. 



Pitcairnia kunhardtiana L. B. Smith, sp. nov. Fig. 21. 



Florifera ultra 1.3 m alta; foliis 1.4 m longis, supra glabris, subtus dense 

 adpresseque brunneo-lepidotis, subdense serrulatis, vaginis ovatis, 5 cm latis,
