Anthoceros punctatus, Linn. Sp. pi. 1606 (1753). 



Monoicous, ca3Spitose, small to medium size, bright pale green- 

 in colour. Fronds in layers, thin, subirabricate, spreading in a 

 circular manner, centre depressed and concave, lobes suberect, 

 somewhat dichotomous, oblong and obtuse, without any distinct 

 midrib, if present confluent and confused with both sides of the 

 frond, more or less deeply sinuate, pinnatifid or laciniate, crisped ; 

 cross-section of frond shows about 2 to 3 layers of cells, rarely 5 

 to 6 ; texture delicate, glandular, reticulate ; cells lax, epidermic 

 layer 4-, 5-, and 6-angled, chlorophyllose, chlorophyl granules 

 large, angular ; walls thin ; stomata distinct ; small remote scales 

 scattered over the frond ; radiculose, rootlets pale dirty brown, 

 arising from base or centre of frond. Calyptra antical, lower 

 half 4 to 6 cells thick, inner layer of cells very minute, 

 others irregular in size with very thin walls, oblong-linear, 

 Slightly repand, when young closed at the top, and later rup- 

 tured by the protruding capsule, leaving an irregular lacerate 

 opening, parts of which are torn aw^ay or remain adhering 

 as scariose rudiments. Capsule pedunculate, exserted, very long, 

 black, pod-iike, filiform, arising like blades of grass, tipped with 

 a veil when young, bursting when ripe into 2 valves with a 

 parallel partition. Spores black, strongly echinate, angular, on the 

 convex side beset with blunt prickles, single or 2 and 3 together ; 

 on the other two sides irregularly verrucose. Elaters brownish- 

 black, short and broad, flattish, geniculate, variously contorted.
