TAB. XXXVIII 
Asplenium (Hemidictyon) Purdieanum, Hook . 
Frondibus subcoriaceis opacis cordato-rotundatis pinnatis, 
pinnis 5-7 patentibus submembranaceis lateralibus oppositis 
subsessilibus ovato-lanceolatis breviter acuminatis basi ob- 
lique cuneatis deorsum obtuse productis obtusangulis (sen 
pinnis inaequilateris), terminali subrbombeo-oyata acuminata 
aequilatera nunc subbastata lobis inaequalibus, yenis mar- 
ginem versus anastomosantibus, stipite rachique compressis 
subulatis fusco-paleaceis, radice fibrosa. 
Hab. Moist woods, La F undacion, Jamaica, Pur die. 
This appears to be an entirely undescribed F ern of peculiar 
habit, having the fructification of an Asplenium (verum) and 
the venation of Hemidictyon s except that it wants the marginal 
vein which unites the terminal veinlets in the latter genus. 
This will consequently rank with the Asplenium Finlaysoni- 
anum 9 represented on our preceding plate ; differing however 
in the shorter broader frond, the paleaceo-setose stipes and 
rachis, the less acuminated pinnae, which have the lowest half 
the broadest and most disposed to form an angle or auricle, 
(not the upper one). The root here too is simply fibrous, not 
forming a knob-like caudex.
