OCTOBLEPHARUM, Hedw. 
O. RADULA, Thw. et Mitt. 
Caulis gracilis ruber furcatim divisus; folia a basi oblonga, erecta, parum 
latiora, superne margine denticulis ciliata integerrimave, cellulis hya- 
linis areolata, exinde pateutia subsemitorta sensim angustata, nervo 
crasso obscuriuseulo subtrigono-tereti intus extusque setulis brevibus 
papilloso, apicem versus excurrente ibique denticulato percursa, et prz- 
terea laminam angustam pellucidam e cellula singula latam, utroque la- 
tere levem, foliorum partem superiorem totam constituente, limbo mar- 
ginali angustissimo subserrulato circumdata nec nisi lesione cernenda. 
Hab. Ins. Ceylon. Dr. Thwaites. 
Caulis unciam altus. Folia sesquilineam longa, cujus 2 erecta, reliqua 
patentia, albida, siccatione immutata.

S. ALBIDUS, Thw. et Mitt. 
Caulis gracilis elongatus; folia sparsa tertia parte inferiore eorum longi- 
tudinis erecta, cauli appressa suboblonga, superne latiora, cellulis 
hyalinis areolata, inde in folium patens lineare planiusculum apice 
obtusum denticulatum producta, margine limbo angusto cartilagineo 
ubique circumdata, integerrima, nervo levi percursa, cellulis rotundis 
obscuris przcipue extus protuberantibus papillosa. 
Hab. Ins. Ceylon. Dr. Thwaites. 
Caulis 1-13 unciam altus. Folia vix bilinearia albida dilutissime viridi 
tincta, sicca vel humida patentia immutata. 
In habit this species resembles S. tristichus, Nees, but is more 
slender and of a paler colour. 
S. caspirosus, Thw. et Mitt. 
Dense cespitosus, mollis ; caulis elongatus furcatim ramosus ruber ; folia 
dense inserta erecto-patentia laxe imbricata anguste lanceolata acuta 
obtusiusculave planiuscula inferne canaliculata, nervo angusto pallido 
percursa, dorso in folii medium papillis scabro, ceteroquin levi, mar- 
gine limbo angusto pallido, a folii medio minute, apice evidentius ser- 
rulato, cellulis hyalinis ultra folii medium longitudinis ascendentibus, 
superioribus minutis obscuris intus extusque minute papilliferis. 
Hab. Ins. Ceylon, regio subtropica. Dr. Thwaites. 
Caulis unciam altus. Folia sesquilineam longa, inferne albida, superne 
pallidissime glauco-viridia, exsiccatione directione parum mutata. 
Larger than S. rufescens, Hook. et Grev., but with narrower 
leaves.
