560 Cook : A Synopsis of the 



" In the western part of the island of Puerto Rico, near the 

 village of Yrurena, in swampy places on the margins of aboriginal 

 forests at an altitude of 400 feet ; collected by Wylder, 1827." 

 (Martius Hist. Palm. 3 : 281.) 



A specimen to which the above diagnosis would not be inap- 

 plicable was collected by Sintenis in the mountain forests near 

 Maricao (no. 484). It was distributed from Berlin as a Mar- 

 tinezia, together with two other very young plants and a seed to 

 which one of these was attached. 



The seed evidently did not come from a cocoid palm but to- 

 gether with the young seedlings may belong to Acrista. The 

 large spiny plant is probably a young specimen of Curium, and 

 should these suggestions prove to be correct the specific name 

 acautJiopliylla must be transferred to this genus though whether 

 it will replace colophylla or not is not to be determined until it can 

 be ascertained that the Maricao species is the same as that here 

 described from Bayamon. 



Bactris Pavoniana Martius, Palm. Orbign. 70 



" Frond pinnate, rachis with rather long spines and black bris-' 

 ties : linear acuminate, about equally distant, the terminal united, 

 setose-ciliate, glaucous below and with a sparse whitish down." 



"Puerto Rico; Pavon." (Martius, Hist. Pal. 3 : 282.) 



Grisebach has reported this species from Antigua and has re- 

 described it as follows, presumably from the Antigua specimens. 



"'Trunk low'; leaves pinnatisect : segments numerous, grass- 

 like, linear-acuminate or the uppermost broader by cohesion, glau- 

 cous and minutely puberulous or glabrescent beneath, approxi- 

 mate, subequidistant, reduplicate at the base : rachis armed with 

 very long black prickles and rare bristles, keeled above. Flowers 

 unknown ; leaf-segments (in our specimens, which are cut off, 

 perhaps about the middle of the rachis) more than 30-jugal, 3'" 

 6'" distant, 1 2"- 8" long, 4'"- 2'" broad, superior gradually 

 shorter, the uppermost cohering ones sometimes 6'" 8'" broad : 

 prickles scattered or clustered, slender, the greatest 2" long. 

 Hai?. Antigua: WullschL, Blubber valley ; [Portorico]." (Grise- 

 bach, Fl. Brit. W. I., 520. 1864.)
