POLYSTICTUS SANGUINEUS (Linn.) Mey. Esseq: 304. Plate Iv, fig. 2. 



Boletus sanguineus Linn. On trunks of dead coco trees, at The

 living and dead coco trees, Cozumel (1614). 



POLYPORUS SIMILIS Berk. Fung. Braz: 6.

AGARICACE.E. 



LENTINUS NICARAGUENSIS B. & C. N.Pac.Expl: 85. Plate Iv, fig. 5. 



On dead wood under edge of log, woodlands near Spot Bay, 

 Grand Cayman (1356). In same situation, center of Cozumel, and

SELAGINLLACE^:. 



SELAGINELLA CUSPIDATA Link. Fil. Hort. Berol. : 158 (1841). 



Plentiful near the cenote Nohoch Chen, Chichen Itza, Yucatan 

 (1620), called by the Mayas X-mux-coc, "dried pectoral," although 

 no use is made of the plant in asthma, difficult breathing, or kindred 

 complaints by the Mayas of the present day so far as I am able to 

 determine. It is used as a remedy in catarrhal affections of the chest 

 when expectoration is profuse. A literal translation of the Maya name 

 is mux dried or desiccated; coc asthma, difficult or wheezy breathing, 

 the prefix X simply denoting the feminine gender. Selaginella longis- 

 picata Underw. Field Col. Mus. Bot., 1:287, is a l so called X-mux-coc; 

 the two species are used indiscriminately in domestic medication. 



PTERIDOPHYTA.* 

 POLYPODIACE^:. 



ASPIDIUM SCOLOPENDRIODES (Linn.) Mett. Aspid. 97. 



Polypodium L. Nephrodium Hook. Dryopteris Ktze. Shady rock 

 clefts near Port Antonio, Jamaica (912, 1133). 



Good characteristic specimens of this species which holds a most 

 unsatisfactory position. I have not yet been able to find any trace of 

 an indusium in any specimens that I have seen. If one ever exists it 

 must be " very fugacious " indeed. Its affinities are nearer to Goniop- 

 teris, where Presl placed it. 



ASPIDIUM MOLLE (Jacq.) Swartz Syn, 49. 



Polypodium Jacq., Lastrea Bory, Nephrodium Desv. , Polypodium 

 parasiticum Linn. Dryopteris parasitica (L.) Ktze., Nephrodium para- 

 siticum (L.) Shimek. I have not been able to satisfy myself that A. 

 parasiticum (L.) Swtz. (Polypodium parasiticum Linn.) is identical with
