256 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I26 



their route discloses the collection was made in Peru more than a 

 thousand kilometers from where the river enters Brazil. 



Dyckia altissima Lindl. Bot. Reg. 27:84. 1841; Mart. Fl. Bras. 3, pt. 3:473. 

 1894. 



This species was described from Argentina and then extended to 

 Brazil by the erroneous inclusion of D. princeps Lem. and other 

 distinct species. 



Hohenbergia gnetacea Mez in Mart. Fl. Bras. 3, pt. 3 : 272. 1891. 



The species is native to Jamaica, not to Brazil as originally stated. 



Hohenbergia pycnantha (Baker) Mez in Mart. Fl. Bras. 3, pt. 3:273. 1891. 

 Aechmea pycnantha Baker, Handb. Bromel. 41. 1889. 



This is a synonym of Hohenbergia polycephala (Baker) Mez, an 

 endemic species of Jamaica. 



Pitcairnia inermis (Meyer) Meyer ex Schult. f. in R. & S. Syst. 7: 1238. 

 1830; Mart. Fl. Bras. 3, pt. 3:440. 1894. 

 Pourretia inermis Meyer in Presl, Rel. Haenk. i : 123. 1827. 



In Flora Brasiliensis Mez states categorically that this species is in 

 Brazil ("In fines Brasiliae septentrionalis descendit"), yet gives no 

 citation to corroborate. In the Pflanzenreich he drops the claim 

 completely and none of the collections are near enough to make it 

 seem probable. 



Pitcairnia nigra (Carr.) Andre, Rev. Hortic. 60:365. 1888; Mart. Fl. Bras. 

 3, pt. 3 : 461. 1894. 

 Neumannia nigra Carr. Rev. Hortic. 53:390. 1881. 



This species was described from cultivation and its origin surmised 

 as Brazil. Subsequently it has been collected in Colombia and Ecuador 

 far from the Brazilian boundary and at altiudes that make its occur- 

 rence in the Amazon Basin appear most unlikely. 



Pitcairnia poeppigiana Mez in Mart. Fl. Bras. 3^ pt. 3:461. 1894. 



The only collection of this species is from Peru. Mez's suggestion 

 that the species may also occur in Brazil is not too improbable al- 

 though the type locality is about three hundred kilometers distant, 



Pitcairnia recurvata (Scheidw.) K. Koch, Ind. Sem. Hort. Berol. for 1857: 

 App. 4. 1858 ; Mart. Fl. Bras. 3, pt. 3 : 460. 1894. 

 Piiya recurvata Scheidw. Allg. Gartenz. 10 : 275. 1842. 



This species was described from cultivation with Brazil as its sup- 

 posed origin. Subsequent collections from the wild have been limited 

 to southern Mexico, British Honduras, and Guatemala.
