A S. palustre (Europza) proxima differt : caule strictiore, foliis caulinis

ducto, cellulis minoribus densioribusque intense rufescentibus ; superiora 
flexuosa, concava, latiora, oblongo-lanceolato-subulata, integerrima, cellulis 
basilaribus anguste pentagono-linearibus rufescenti-diaphanis, intermediis 
elongatis pellucidis pallidioribus in subula linearibus, omnibus interstitiis 
tenuioribus notatis lutescenti-diaphanis. Theca obtuse acuminata ; calyptra 
brevissima, campanulata, stylifera, basi lacera glabra. 
Hab. Bogota, Pacho (3200 met.), inter Illecebrariam, Lindig. 
S. Schwegricheni nostre ( — S. Hampeane) proxima ; differt : foliis su- 
perioribus latioribus, magis pellucidis, nec subula opaca.— Hampe, l. c. 
2. PrEURIDIUM, Brid. ii. 160. 
Musei pusilli. Folia setacea, pallide viridia, nitida. Thece 
tener, cartilaginex, nitentes, inter folia perichetialia fere sessiles ; 
demum fatiscentes. Habitatio ad terram nudam. 
P. Rosinsonir (Mont. in Ann. Sc. Nat. ser. 2. iv. 96, Phascum). 
Folia appressa, imbricata, inferiora et ramorum sterilium minora, julacea, 
late ovata, obtusiuscula, marginibus superne minute crebreque crenulatis, 
nervo percursa; superiora ovalia, concava, nervo latiusculo canaliculato in 
mucronem subulatum excurrente, marginibus subintegerrimis, cellulis in- 
ferioribus elongatis rectangulis, superioribus ovalibus. Theca breviter ovalis, 
acuta, subsessilis, nitida, fulva. Flos masculus ad caulis pedem, gemmi-

Caulis 1-2-linearis. Folia straminea, nitida. 
This appears to differ from P. nervosum, Hook. Muse. Exot. 
t. 105, in its leaves, more especially those of the perichetium, 
being shorter and, in proportion, wider. P. curvulum, Tayl., from 
Australia and New Zealand, is nearly intermediate in the form of 
its leaves. All these species differ in appearance from the Euro- 
pean P. subulatum, Linn., and P. alternifolium, Bruch et Schimp., 
in having their inferior leaves and those on the barren shoots 
without the subulate points, closely imbricated in a julaceous 
manner, with their upper margins minutely crenulate.
