Weissia cucullata Mull.Hal.
Indigenous Endemic

Morphological description

Plants small, loosely caespitose, yellow- green; terricolous. Stems 2-4 mm tall, occasionally branched below; in section round, central strand small, cortical cells incrassate, outer row smaller. Leaves contorted-incurved dry, erect-spreading wet; linear-lanceolate, to 2 mm long; apex acute, weakly cucullate, mucronate; base oblong; margins narrowly incurved, entire. Costa short-excurrent, ventral superficial cells elongate, smooth, dorsal superficial cells long- rectangular, smooth; in section oval, guide cells 4, ventral stereid band strong, 2-3 cells thick, ventral surface cells undifferentiated, dorsal stereid band 3-4 cells thick, dorsal surface cells undifferentiated. Upper laminal cells quadrate, thin-walled, papillae on ventral surface large, branched, 1-2 over lumen, on dorsal surface low, numerous, scattered; basal cells rectangular, hyaline, smooth, thin-walled. Autoicous. Perichaetia terminal, leaves similar to vegetative leaves, but slightly larger. Seta 2-3 mm long, yellow; capsule hymenostomaceous, oval, constricted at mouth, 0.8-1.0 mm long, reddish yellow; peristome absent; operculum rostrate, 0.3- 0.4 mm long; spores round, 25 µm, strongly papillose.

Diagnostic description

The small, linear-lanceolate leaves, acute-cucullate apices and hymenostomaceous capsules help to identify W. cucullata. The spores are also larger than those of any other Southern African species of Weissia. From: Magill, RE. 1981. Ditrichaceae to Grimmiaceae. In: OA Leistner (ed.). Fl. S. Africa Bryophyta(1,1): 83-281. Botanical Research Institute, Department of Agriculture and Water Supply, Pretoria. [https://doi.org/10.5962/bhl.title.119879] [CC BY]

Habitat

On soil. From: Magill, RE. 1981. Ditrichaceae to Grimmiaceae. In: OA Leistner (ed.). Fl. S. Africa Bryophyta(1,1): 83-281. Botanical Research Institute, Department of Agriculture and Water Supply, Pretoria. [https://doi.org/10.5962/bhl.title.119879] [CC BY]

Distribution

Endemic to Southern Africa, this species is known only from the type specimen.
