10. H. caLvciNuM (Sw., Hedw. Spec. Muse. t. 14). Folia apice serru- 
lata, nervo percurrente dorso levi, cellulis alaribus numerosis fuscis, inde 
elongatis angustis, superioribus omnibus elongatis oblongisque ; periche- 
tialia ad thece basin usque laxe convoluta, flava, apicibus subulatis an- 
gustis, thecam longe superantibus. Theca elliptieo-cylindracea. 
Hab. Jamaica, Swartz, Wilds, etiam ex Herb. Brown. 
Caulis 1-2-uncialis. Folia superiora fulva, 3-linearia, inferiora fusces- 
centia, sicca cirrhato-incurvata. Pedunculus 6-linearis. 
This species appears to be distinct from H. Sellowii and from 
H, Moritzianum in the substance of the leaves, as well as in the 
rather more compact habit. All the specimens agree in having 
their leaves everywhere fulvous.
