nervo crassiusculo sub apice evanido carinata, marginibus erectis integerri- 
mis, cellulis superne oblongis obscurioribus ; perichzetialia elliptica, con- 
voluta, anguste subulata,'apicibus obtusiusculis. Theca in pedunculo 
gracili, ovalis, rufa, subzequalis, erecta, operculo subulato, peristomio parvo, 
dentibus brevibus pallidis dicranis. 
Hab. Guadelupe, in monte sulphurifero (4000 ped.), Richard, Parker 
et Guilding. Brasilia, Parahybuna, Gardner, n. 19. 
Caulis 2-3 lineas altus. Folia å lineam longa, luteo-fusca. Pedunculus 
sub 3-linearis, rufus. 
Gardner’s specimens, n. 19, do not appear to differ from those 
from Guadelupe. 
5. D. HiLARIANA (Mont. in Ann. Sc. Nat. ser. 2. xii. 52, t. 1. f. 2, 
Dicranum). * Ceespitulosa, humillima, subsimplex, basi innovando divisa. 
Folia caulina plicato-flexuosa, apice suberosa, basi e cellulis laxis elongatis 
teneris flavide pellucidis, superne minutis et minutissimis pellucidis areolata, 
nervo canaliculato angusto flavo flexuoso crassiusculo ante apicem evanido ; 
pericheetialia distincte obtusa. Theca in pedunculo brevi, ovalis, brunnescens, 
minuta, sicca cylindrica, operculo longe et oblique subulato; peristomii 
dentes inflexi, rubri, ad medium usque bifidi, cruribus tenuissimis hyalinis 
longis subrugulosis."— C. Müll. Syn. i. 442. 
Hab. Brasilia meridionalis ad terram, Herb. Montagne. 
From the description, this appears to be very near to D. longi- 
rostris, if not, indeed, identical. 
6. D. PvsiLLA (Hampe in Ann. Sc. Nat. ser. 5. iii. 358, Angstroemia). 
Caulis brevissimus. Folia margine superne recurva revolutave, apice sub- 
crenulata, nervo crassiusculo percurrente carinata, cellulis basilaribus elon- 
gate oblongis pellucidioribus, superioribus abbreviatis rotundis obscuris. 
Pedunculus brevis, luteo-viridis. Theca ovalis, erecta, operculo rostrato, 
* peristomii dentibus lanceolato-subulatis tenerrimis, basi croceis, apice 
pallidioribus fere usque ad basin divisis." 
Hab. Andes Bogotenses, Pic de Cuesta (1200 metr.) in convallibus 
“ Barrancas,” Lindig. 
Caulis $ lineam altus. Folia viridia 3-linearia. Pedunculus 14 lineam 
longus. Theca rufo-fusca. 
7. D. Passtiana (C. Müll. in Bot. Zeit. 1857, 380, Angstroemia). 
Caulis brevis. Folia densiuscula, superiora lanceolato-subulata ; peri- 
cheetialia inferne elliptica, superne subulata; omnia apicibus obtusiusculis 
subintegerrimis, nervo sub summo apice evanido carinatis, marginibus 
medio revolutis, cellulis basi elongatis, superioribus minutis oblongis 
obscurioribus. Theca in pedunculo breviusculo, oblongo-cylindracea, 
erecta, operculo subulato, peristomii dentibus rubris dicranis. 
Hab. Brasilia, Santa Catharina, Pabst er Herb. C. Müller. 
Very nearly resembling D. longirostris, but remote from D. 
Guilleminiana, the leaves having no vaginant base.
