Isopterygium andamanicum Gangulee, Mosses E.

15. Isopterygium andamanicum Gangulee, Mosses E. View in CoL India 8: 1953. f. 1002. 1980.

Protologue: Typus lectus a E. H. Man in Andamania ( Port Blair ), anni 1893, et positus in Bryotheca E. Levier in BM sub numero 2477 .

Label: Bryotheca E. Levier, in insula Andaman merid. Port Blair, 1893, legit E.H. Man determ. C. Mueller sub no 2477 (holotype: BM, isotype: LE!). Comments: the holotype is at BM, unfortunately we were not able to study it during our visit to BM (possible was on loan), but the curators later provided a picture of the specimen (and its label) confirming it is housed there. Concerning the number 2477, it is believed that it is not the collecting number, but a Bryotheca Levier’s number. This can be inferred both by the protologue as well as from the labels. The number 2477 was never associated with the collector’s name, but with the collection’s name. In the label, there is a space for the collector’s number after a coma, but it is empty (there is no number after Man’s name). So we are considering the voucher as Man s.n. (and 2477 as an herbarium number). There are also some specimens housed in Paris (PC) that match the name, collector and collecting year, but differ from the Bryotheca Levier’s number, so we are not considering them as types. Also the presence of “ nov. sp.” on the label indicates that the author intended it to be a new species.
