omnia dense imbricata leviter plicata, humida squarroso-patentia, e basi 
paulo angustiore parce plicata, late ovato-lanceolata, acuminata, apice 
remote sinuato-dentata, nervo solido lutescente percursa, in acumine inte- 
gerrimo evanescente, cellulis lateralibus dense aggregatis angulato-rotundis 
hyalinis, intermediis aureis elliptico-linearibus, czeteris ellipticis, versus 
apicem folii abbreviatis in acumine laxioribus ovalibus, tota flavescenti- 
diaphana. Theca breviseta, magis exserta, oblongo-ovata, celluloso- 
punctata, rubra, peristomii dentibus exterioribus flavidis, internis cruribus 
albidis.— Hampe, l. c.

P. denso proximus, sed colore et structura nervi differt.— Hampe, l. c. 
3. P. LnycoproDrorpEs (Hampe in Linnea, xxxii. 150). Rami elongati, 
inferne simplices folis parvis appressis, superne ramulosi, ramulis in- 
iequalibus distichis pinnati vel flabellati. Folia compressa, oblongo-lanceo- 
lata, acuminata, triplicata, paulo infra apicem subexcavata, margine plana 
a medio ad apicem usque serrata, nervo infra apicem desinente, superne 
flexuosa, cellulis basilaribus ad latera minutis rotundis, interioribus ob- 
longis ellipticisque, superioribus omnibus rotundatis; pericheetialia erecta, 
convoluta, ovata, abrupte apiculata, margine crenulata, nervo angustissimo 
percursa. Pedunculus ultra perichztium paululum productus. Theca 
oblongo-ovalis, subinelinata, operculo conico-rostrato; peristomii dentes 
pallidi, interni processibus punctulatis interdum hie illic anastomosantibus, 
inferne parum pertusis.

fertilis, Weir, n. 136. Andes Quitenses, in monte Tunguragua, Spruce, 
n. 1307, planta mascula. 
Rami 4-6-unciales, ramis longioribus biuncialibus, cum foliis 13 lineam

longa, fusca. 
Species pulchra, Selaginellis nonnullis primo visu similis. 
4. P. pensus (Sw. Prodr. Fl. Ind. Occ. 141; Hedw. Sp. Musc. t. 74,

lata, longitudinaliter plicata, e basi ovata sensim lanceolato-subulata, nervo 
sub apice evanido, marginibus denticulatis, cellulis basi ad margines 
pluribus parvis rotundis, interioribus elongatis, superioribus ovoideis 
rotundisque minutis, postice parce papillosis.
