By this mail, Jenman sends a small package of fern specimens that he would like named. Some of them are not in 'Gr's' [Grisebach's] flora; others probably are but not so clearly defined that he can determine them with satisfaction. Many of them are from Mr Nock who has devoted his leisure to searching for ferns and has discovered several rare species. Ophioglossum palmatum is not noticed by Grisebach, but both Jenman and Nock have met with it and Jenman has it doing very well in cultivation. Mr Nock has written to Jenman regarding a case of ferns he sent Hooker by the last packet. Nock mentions two species of Trichomanes, one of which he appears to have made an error with: Hymenophyllum abruptum. Jenman asks if the second edition of the SPECIES FILICUM now advertised contains all the Jamaican ferns discovered to the date of its issue. Annotated. Pages 1 and 4 of 4.
