from the coriaceous.leaved plants referred to P. argyrophyllum. Whether, however, 
what I have described above should be regarded as Miquel's P. Wightii is perhaps 
doubtful, there being much confusion in both Wight's and Arnott's Herbaria, where 
alone authentic specimens of Miquel's plants are preserved. Miquel’s description of 
leaves sparsely hairy on the nerves, together with specimens named by Miquel P. 
Wightii in Herb. Arnott with this character, obviously apply to P. Hymenophyllum ; 
others equally authentically named P. Wightii, and quite glabrous, with membranous 
leaves, are identical with forms of P. argyrophyllum (perhaps sylvestre) ; whilst still 
a third 'series, with coriaceous leaves and more basal stronger nerves, also named 
Wightii by Miquel, represent that plant as here limited. Furthermore, specimens of 
this last in Arnott’s Herbarium are named by Miquel * P. nigrum forma sylvestre.” 
In short the confusion is inextricable, and I cannot say whether P. sylvestre, argyro- 
Phyllum, Hymenophyllum and Wightii represent as many species, or fewer, or one 
only. Lastly, P. Wightii must be carefully distinguished from P. Schmidti (P. 
. arborescens Miq. not of Roxb.), which though not easily distinguishable by words is 
à very different species.

DC. changes Wallich’s name to P. indicum, citing as the authority Miquel’s Systema 
(p. 815), where, however, thé name leptostachyum is preserved, and I find no autho- 
nity in Miquel for the name P. indicum. The P. leptostachyum of A. Richard is 
undescribed, and only mentioned in Grisebach's Cat. Pl. Cub. 69.  Miquel's citation of 
Wall. Cat. 1540 for this is an error.
