Rad. aquilegia in „Transactions of the Botanical Society of 
Edinburgh“ Vol. IE. (1845) p. 115—117 — „Contributions to 
British Jungermanniae. By Thomas Taylor Med. Doct, F. L 
5. etc, (Read 9 th. May 1844)“ lautet: 
p. 117 ur. 6 — Jungermannia aguilegia Tayl. ınss. 
Caule caespitoso, prostrato, subpinnato; ramis complanatis; 
foliis imbricatis, erectiusculis, eonvexis, integerrimis, lobo supe- 
riori obovato-rotundato, margine recurvo; inferiori minori sub- 
quadrato ex tumida involuta basi apice adpresso; perichaetia- 
libus oblongis transversalibus deflexis; ealyeibus elongate ob- 
conieis truncalis integerrimis. 
Jung. complanata, f. minor, Hook. Brit. Jung. tab. 81 fig. 17. 
On rocks over which water continnally trickles, Patches 
wide, shallow, brownish olive. Stems 1—4 inches long, irre 
gularly pinnate; the branches nearly at right angles to the stem. 
Leaves from a narrow base, faatly cup-shaped; their lower 
lobe swelling out at its involution, white their angulale 
tops lie elosaly adpressed to the inside of the upper lobe. 
This species differs from Jg. complanala L., by the smaller and 
more convex leaves, their olive-brown colour, their lesser lobe 
not sharply refleeted upon the upper but having a tumid base, 
by the deflexed perichaetial leaves, by the perigonia occuring 
usually ab the terminstion of the shoot and not on proper 
short lateral branches, and by the angulate portion ofthe lower 
lobes of. the leaves being shorter. This species prefers very 
wet surfaces of mural rocks, while J. complanala L., is partiel 
to trees.

On exposed rocks, Cromaglan 9! Abundant near Cooms- 
shana Lake, Dingle Bay 5’ plants. 
Dioieous! so that it cannot be a variety of Rad. complanala, 
as Hooker described it; known also by the smaller size, tumid 
involute lobes, and olivaceous colour. Dr, Hooker may be 
correct in referring this species to Rad, physoloba, Mont. with 
which also R, fiavifolia Tayl., must bi united. ..
