subquadrata cellulis inferne elongatis angustis subito angustatis 
lanceolatis lamellis obtectis apicem versus parce serratis, pericheti- 
alibus conformibus, theca in pedunculo longo aurantiaco ovali-cylin- 
drica erecta inclinatave, operculo breviter conico rostro brevi, calyptra 
pilosa thecam totam obtegente, flore masculo foliis perigonialibus 
hastato-ovatis breviter acuminatis. 
Hab. In Himalays orient. reg. temp., Sikkim, J. D. Hooker! (No. 
1193, 1194, 1204, 1235). 
P. Teysmanni (Dozy et Molk.) valde affine, sed foliis a basi quadrata 
subito angustatis angustioribus recedit. 
14. P. ruscatum (Mitten). Caule elongato simpliciusculo, foliis sic- 
citate incurvis subcrispatis humidis patulis e basi subquadrata, cellulis 
infimis parvis firmis oblongis ceteris rotundis paululum angustatis 
lanceolatis acutis lamellis obtectis margine e medio ad apicem dor- 
soque argute serratis, perichetialibus externis conformibus internis 
angustioribus, theca in pedunculo unciali erecta inclinatave ovali- 
eylindracea, operculo hemisphserico brevirostrato, calyptra thecam 
totam obtegente. 
P. cirrhatum, Wils. in Sched. 
Hab. In Himalayz reg. temp., Nepal, Wallich! Sikkim, J. D. Hooker! 
(No. 1225, 1233,1242). In mont. Khasian. reg. temp., J. D. Hooker 
et T. Thomson! (No. 1203, 1230). Kumaon, Strachey et Winter- 
bottom ! 
P.cirrhato dimidio minus, folis fuscis basi dilatata angustiore inte- 
gerrima. 
15. P. FASTIGIATUM (Mitten) Caule elongato simplici dichotome 
fastigiatimque ramosove, foliis siccitate incurvis cirrhatis a basi la- 
tiore ovata erecta, cellulis parvis elongatis parallelogrammaticis 
patulis divergentibusque longe lanceolatis lamellis brevibus densis ob- 
tectis, margine a basi infima ad apicem dorsoque superne serratis, 
pericheetialibus basi longiore convolutaceis, theca in pedunculo brevi 
semunciali ovali-cylindrica erecta inclinatave, operculo convexo bre- 
viter rostrato. 
Polytrichum convolutum, Wils. in Sched. 
Hab. In Himalays orient. reg. temp, Sikkim, J. D. Hooker! (No. 
1182, 1183, 1202, 1240). In mont. Khasian., ad Kollong, J. D. 
Hooker et T. Thomson. 
Species P. cirrhato et P. macrophyllo (Dozy et Molk.) intermedia. A 
P. convoluto Americ meridionalis, icone Schweegricheniano satis 
bene illustrato, foliis angustioribus opacioribus rigidioribus et a basi 
infima serratis recedens; a P. cirrhato, ad quod serratione foliorum 
accedit, foliis latioribus tota superficie lamellis brevissimis obscura, 
siccitate magis crispatis crassioribus, theca in pedunculo breviore; a 
P. macrophyllo, statura affiniore, foliis magis cirrhatis obscuris et e 
basi serratis, diversa.
