the margins of the leaves. The cells bordering the mouth are 
smaller, which gives it a more pyriform urceolate shape when dry.

Mosses No. 25 (1848), non Brid. Bryol. Univ. 1: 100 (1826). 
Autoicous, the antheridia terminal and cotemporaneous with 
the fruiting axis. Plants gregarious, tall slender, 3-4 cm. high ; 
stems 25mm. tall, branching repeatedly and rooting at the joints; 
lower leaves short distant, with the vein ending below the apex, 
upper 3-4mm. long, 8-10’ crowded around the base of the seta, 
all narrow oblong-lanceolate, serrate above ‘the middle, marginal 
cells narrower and longer, teeth small appressed ; vein ending 
below the acute apex ; seta short, 5mm., pale, twisted and curved; 
capsules often cernuous, subglobose, becoming turbinate, and 
aring at mouth when dry and empty, small, 1-1.5 mm. long, 
often broader than long, neck tapering, contracted stomatose ; lid 
flat and apiculate when dry, conic when moist, bordered with 
brown; mouth bordered by 5-8 rows of large, clear cells and a 
darker annulus, with a second row of hyaline cells incurved and 
almost invisible, cells of the walls irregular with thick walls ; 
Spores rough, warty brown, .037~.043mm., maturing in spring. _ 
Type locality Apalachicola, Florida, Drummond’s No. 25, 
1848. Not since collected, though specimens gathered by Dr. 
Garber in Southern Florida in 1878, and distributed as No. 268, 
resemble this species in the tall, leafy stems, but the pedicels are 
much longer, not curved, and the mouth is bordered by 8-12 rows 
of cells, and the spores are smaller. They are probably referable 
to P. turbinatum var. Langloisit, and show connecting characters. 
_ The var. Langlotsit seems to bear the same relation to P. tur- 
“Haun as var. calvescens does to Funaria hygrometrica, and P. 
q\Salis corresponds to var. patulum. In both cases they are 
uthern in range, and are propably due to extreme heat and 
Moisture in early spring. They both fruit earlier than the species 
#: the North, and are taller, more slender and yellowish green.
