292  ROWLEE: GENUS CosTUS IN CENTRAL AMERICA 
13. COSTUS SPLENDENS Donn. Sm. & Tuerckheim; Donnell 
Smith, Bot. Gaz. 33: 260. 1902 
Costus maximus K.Schum.; Engler, Pflanzenreich 44°: 405. 1904. 
Costus giganieus Kuntze, Rev. Gen.2:687. 1891. Not Ridley, 
1887. 
The species was based on a specimen collected in Guatemala 
at an altitude of 350 m., by H. von Tuerckheim (No. 8015), no 
more definite locality being mentioned. The writer has not seen 
the type specimen, but other material collected in Guatemala by 
Von Tuerckheim and referred to C. splendens has been available 
for study. Jn this material the bracts bear a callose below the 
apex, although no structure of this sort is mentioned in the 
original description. Since these specimens are indistinguishable 
from C. maximus K.Schum., the name C. splendens will have to 
supplant the later name C. maximus, and the known range of 
the species will extend from Guatemala to Panama. 
14. Costus LAxus O. G. Peters.; Martius, Fl. Brasil. 3%: 56. 
1890 
The type specimen was collected in Costa Rica by Aented 
in 1847, the name of the locality being illegible. The species 
is known also from Venezuela.
