centii. Rev. L. Guilding. 



Caudex longe repens, gracilis, filiformis, radicibus tomentosis dense obsitus. 



Stipites breves, vix semiunciam longi, ferrugineo-tomentosi. 



Frondes plurimse, pollicares, ovatae, obovataeve nunc rotundatae, basi semper cuneatae, marginibus apiceque varie 



modo crenatis lobatis incisisve, hic illic fasciculatim pilosis, pilis minutissimis reflexis. Substantia tenera, 



membranacea, minutissime reticulata, pulcherrime venosa, vix costata, sed venis e basi versus margines radia- 



tim, vel potius flabellatim ramosis. Color laete viridis, nunc fuscescens. 

 Involucra solitaria vel bina, ad apicem frondis, plerumque in sinu lobulorum, fere omnino exserta, cylindracea, 



nuda, vel, inferne, marginibus utrinque alatis, apice bilabiata, labiis subrotundatis demum apertis. 



Receptaculum filiforme, nostris speciminibus nunquam exsertum, medio capsuliferum. 



Cajpsulce oblique insertae, sessiles, annulo completo instructae. 



Semina subsphaerica.

Numerous beautiful specimens, received from our friend the Rev. Lansdown Guilding, of this 

 minute Fern, enable us to give what we trust will be found to be satisfactory figures of this little 

 known, though we believe not uncommon, species. The only ones that exist, that we are aware of, 



* 



are that of the younger Hedwig, which is acknowledged by Willdenow and Smith to be bad ; and 

 that of Sloane, which, though usually (and even by Swartz) quoted under Tr. muscoides, we think is 



better referred to this. 



We have reason, indeed, to believe that the Tr. muscoides and reptans have been confounded by 

 botanists ; but the former differs from the latter (as we propose on another occasion to show inore 

 clearly by a plate) by its narrower, more beautifully reticulated and less veined frond, in the sub- 

 stance of which the involucres are inserted. We have another nearly allied specics from Guiana, 

 gathered by Mr. Parker, in which there is a strong nerve, having only as many divisions as there 

 are lobes to the frond.
