Notes

At Paris is a specimen of Zollinger 1442 named Asplenium erectum Willd., ex Herb. Drake, from East Java, "ad pedem Mt Lamon- gan 1500', Jan. 1845". v.A.v.R. records a cul- tivated plant at Bogor originating from Celebes, collected there by Koorders. These are the only known records of the occurrence of the species in Malesia.
A small indusium was first described by J. Smith in Lastrea decurrens. Ching and Iwatsuki have stated that the receptacle bears a tuft of hairs, not an indusium; but there is a distinct flat structure with hairs on its margin which I would not call part of the receptacle.
Mitui has recorded diploid and tetraploid conditions in the species, but no-one has distinguished the two forms from other characters, and I cannot see clear distinctions among herbarium specimens.
For some years a plant flourished in cultivation in the Botanic Garden at Penang but did not reproduce itself from spores. Plants grow well in the Temperate Fern-House at Kew.
