 (Jurdncr. — This is a rather soft and flaccid species, more easily recognizable 

 ))y the eye than described in words. The sori are very copious on the seg- 

 ments ; the involucre opaque, lirm, not readily bursting, but, while entire, 

 ti])ped wiih a dark-coloured umbo.

Hab. Brazil, SvlUnc, Bcyrich. Rio Janeiro, Gardner, n. IWi. — My lirst 

 knowledge of this plant was derived from a line specimen sent to me by Dr. 

 Klotzsch irom the Royal Berlin herbarium ; and it is very remarkable in 

 the large persistent involucres, nut bursting at the top all round, liul dehis- 

 cing as il were vertically horn the top outwards, towards the apix, or more 

 correctly, obliquely tow ards the margin of the segments. The stipes is jiale 

 brown, miiuitely tubereled and also aeuleated, at the base clothed with long 

 brown ehall'y hairs. 'Jhe frond is dark green above, much paler benealh, 

 iij. texture between membranaceous and coriaceous. Mr. Gardner's jdanl 

 seems to be exactly the same, his speeimeii is a little more advanced in age, 

 and of a yellower lint; but the siructuie of the involucres is similar, and 

 may perhaps be considered as more analogous lo that of Ilcmitclii, but it is 

 dilhcult to decide without an examination of young fruit. In the earliest 

 state of the sorus which has co.iie under my observation, the involucre co- 

 vers it entirely, but the point of attachment uppiuis to be only on the lower 

 half of the sorus next the costa. ('. ]Val/tcr<c from Ceylon has a similar 

 structure in its imoliu irs. (sic //. ;53).
