Coccothrinax martii Becc. in Webbia di U. Mart., II (1907), 305. Thrinax

Collected only "by Wright, probably in eastern end of the island, and 

 distributed under n. 3219. 



It is characterized by its leaves being rather deeply divided into numer- 

 ous (about 38) segments, which are lustrous above and silvery-white under- 

 neath, by the flowers having 12 stamens, and by the fruits (7-8 mm. in 

 diameter) borne on a pedicel 2 mm. long on the lower part of the branchlets, 

 and sessile above ; under the lens the surface of the fruit appears very finely 

 punctulate-scabrid. (Figure 171).

This is another of the palms discovered by Wright, probably in the east 

 of Cuba; it has been distributed under the n. 3966. The specimens have no 

 flowers, and bear fruits not thoroughly mature ; these, however, are charac- 

 teristic, as they are distinctly pedicellate (the pedicel is 3-5 mm. long) and 

 not perfectly spherical, as in most species, but more or less distinctly globu- 

 lar-turbinate and apiculate, and have the surface finely and densely granu- 

 late. The leaves are silvery-white on the lower surface and are divided into 

 about forty segments. Inside the fruiting perianth the remains of 6-9 

 stamens are distinguishable. (Figure 172).

I have doubtfully included this very imperfectly known palm in the 

 genus Coccothrinax, as it has a general likeness to C. argentea. It differs,
