Palms of Puerto Rico 531 



glabra Miller, which Dr. Sargent (Silva, 10 : 38) has resurrected, 

 are not likely to be easy of determination, but since the last was 

 based on plants grown from seeds which came from Jamaica, it 

 seems unwise to use it for United States species to which the de- 

 scription is inapplicable. Miller's name may, however, replace 

 Sabal taurina Loddiges which was also founded on a stemless Saba/ 

 supposed to come from Jamaica. 



The species of /nodes are in a similar or even worse state of 

 disorder. There is little use, for example, in transferring to the 

 new genus the traditional name umbraculifera which was based by 

 Martius on the Corypha umbraculifera of Jacquin, but not on Lin- 

 naeus' species of the same name, which is a native of Ceylon. 

 Present taxonomic methods forbid such generic transfers of mis- 

 applied names, so that the name Inodes Blackburniana {Sabal 

 Blackbnruiana Glazebrook, Gardener's Mag. 5 : 52. 18 29) should 

 be used instead of the traditional Sabal umbracnlifera of the con- 

 servatories, though the identity and origin of the species still re- 

 main in doubt. 



Inodes causiarum sp. nov. 



Trunk 45-75 cm. thick at base, 5-15 m. tall, columnar or 

 slightly tapering upward ; surface narrowly rimose or nearly 

 smooth, light gray or nearly white. Leaf-bases splitting into rather 

 brittle fibers, partly remaining compacted into long ribbons 58 

 cm. wide. Leaves about 4 m. long, the petiole subequal to the 

 blade, considerably exceeded in length by the inflorescence. Petiole 

 3.8 cm. wide, distinctly carinate above near the end; ligule 4.2 

 cm. in diameter. Fruit grayish, 910 mm. in diameter; seed 

 chestnut-brown, finely rugose or nearly smooth, 78 mm. in di- 

 ameter ; embryo oblique, at an angle of somewhat less than 45 

 degrees from the horizontal. Type specimen from Joyua (no.

The palm-leaf hats manufactured in large quantities in Puerto 



Rico are made from the present species. The center of the hat 

 industry is at Joyua, a small village on the western coast of the is- 

 land some miles southwest of Mayaguez and west of Cabo Rojo. 

 Here many hundreds of the palms are growing along the shore in 

 a narrow belt of coral sand. 



From the two species of Sabal recognized by Grisebach Inodes 

 causiarum differs from umbraculifera in having the inflorescence
