394 Mr. HooxeEr’s Observations on Andrea. 
obsoletiore, ad apicem percurrente instructis, nigro-viridibus, 
siccitate omninó nigris, sub lente elegantissime punctatis; Peri- 
chetialia reliquis breviora, pedicelli vix longitudinem exceden- 
tia, oblónga vel oblongo-ovata, interiora margine inflexo et pror- 
süs enervia, exteriora nervo obsoleto infra apicem evanescente 
percursa; Perigonialia e basi ovato-subrotundä acuminata, con- 
cava, inferne obsoleté uninervia. 
Fructificatio ; feminea terminalis; Pedicellus vix lineam longus, 
albus, demum fuscescens, desinens in apophysin exiguam, ro- 
tundatam, fuscam, capsula angustiorem ; Capsula ovata, nigro- 
fusca, basi pellucida, in quatuor valvas angustas ad basin usque 
longitudinaliter dehiscens; Operculum conicum, minutum, al- 
bescens :. Mascula gemmiformis, terminalis ; ex Antheris constans 
$—5, ovato-cylindraceis, subpellucidis, pallidé fuscis; et Fila- 
mentis succulentis numerosis, filiformibus, articulatis, flavescen- 
tibus, antheris duplo longioribus. 
The only botanist who appears to have well understood the 
three preceding species of Andrea was the late Dr. Mohr, who 
first described A. Rothii as distinct from rupestris; and gave 
figures of them all in his excellent Flora Germanica. A. Rothii is 
far from uncommon in the mountainous parts of the British 
isles, and is immediately distinguished by its very black colour 
and small size. It is unquestionably the plant intended by the - 
name of A. rupestris in the Muscologia Hibernica, which caused 
Hedwig's figure of the true A. rupestris to be there referred to 
A. alpina, though its most striking character, the midrib of the 
leaves, is not noticed by Mr. Turner. In the neighbourhood of 
Bantry it is so abundant, that, according to Miss Hutchins, the 
mountains are black with it.
