murices are not to be found; all the remaining signs are consistent 
with your description. 4. extensa, R. Br., you have put under Cyathea 
medullaris ; the Alsophila which Bl. En. 246, has designed by this name, 
is surely an Alsophila ; there is no rudiment of indusium to be seen. 
A. melanopus, Hsskl.; arborea (10-15 feet high), stipitibus basi 
valde aculeatis, apice cum rhachi submuticis asperulis, frondibus 3 pin- 
natifidis ovato-oblongis acutis membranaceis subtus leviter glaucescen- 
tibus, pinnis elongato-oblongis acutis aut oblongo-lanceolatis acumina- 
tis, pinnulis lineari-oblongis acuminatis profunde pinnatifidis, laciniis 
lineari-oblongis obtusis aut acutiusculis subfaleatis planis obsolete cre- 
‘nato-serratis, soris alis venarum furcatarum insertis, costulis approxi- 
matis 1-5 laciniarum obtegentibus dein confluentibus ; rhachi subte- 
tragona glabriuscula inermi, paleis minutis subtus ad costulas cadu- 
cissimis, ad apicem trunci et basin stipitum nigrescentibus grandibus - 
copiosis dein deciduis.— This Fern, which grows at the height of be- 
tween 4-8000 feet in the woods of the Gedeh, differs from Z. lepi- 
Jera, J. Sm., stipite inermi, rhachi punctata aspera supra pilis longis 
adpressis vestita, pinnulis longiter subulatis paleis crinitis paucis. 
Your 4. crinita, fronde coriacea, rhachi paleaceo-erinita, supra undique 
pilosa, laciniis anguste ovato-oblongis margine reflexo subtus in costulis 
venisque pilosis, soris paleis crinitis tectis, differs from <. excelsa, R. Br., 
laciniis acute serratis margine reflexis, inferioribus subauriculatis venis 
2—3-furcatis ;—from 4. gigantea, Wall., defectu aculeorum, trunco al- 
tiori, pinnis ovato-lanceolatis opacis, pinnulis oblongo-lanceolatis laci- 
niis ovatis, rhachi strigosa, venis simplicibus, receptaculo calvo, soris 
in medio inter costas marginesque. 
The diagnosis of 4. (Chnoophora, Bl.) tomentosa, Endl., is not suffi- 
cient; here I offer a new one :—Arborea (25 feet high), stipite rhachique 
supra lanato-iomentosa et subtus dense paleacea muricato-aculeatis, 
frondibus ovatis tripinnatifidis aut triplicato-pinnatis coriaceis supra gla- 
bris, subtus cum rhachibus secundariis preeprimis autem in costis costu- - 
lisque dense fulvo-lanato-tomentosis et paleis imbricatis longissimis ad- — 
pressis densissime obtectis, pinnulis lineari-lanceolatis acuminatissimis, - 
laciniis (aut pinnulis secundariis) linearibus obtusis subfalcatis erenu- 
latis, sed margine revoluto quasi integerrimis et acutis, venis 2—3-fur- 
catis, soris inter paleas et tomentum costz et costularum plane occultis. 
— I am not quite sure if this will not prove your 4. crinita, but the la- 
ciniz of this are ovate-oblong, very Zomen£ose, linear !—And lastly, I have
