—rarely more; or are terminal on the branches—or even on the stem— 
aud are then often elongate, having 10 or more pairs of smallish laxly- 
imbricated diandrous bracts. 
The chief variations of L. flava are already indicated above. The Irish 
form (=L. Moorei Lindberg. Hep. in Hibernia lect. 1875)—first found 
near Killarney by Mackay,* and recently by Lindberg and Moore—is 
quite the same as the West Indian, as represented by Swartz’s own 
specimens in herb. Hook. It belongs to the yellow-green form, although 
one of Moore’s specimens has whitish plants intermixed; and it has the 
large underleaves cloven to about the middle, with usually obtuse seg- 
ments,—or with one segment longer and acute, the other shorter and 
obtuse, as is frequent also in 8. American specimens. And it is to be 
noted that some states of L. serpyllifolia have quite as obtuse underleaves 
as L. flava. The large form of serpylli,olia, growing in North Yorkshire 
(Mowthorpe Dale, etc.), has them often very obtuse, but subacute ones 
are also present. The var. cavifolia, as represented by Stabler’s West- 
moreland, and some of my own Pyrenean specimens, has also often very 
obtuse underleaves. 
A few easily-observed characters usually suffice to distinguish every 
form of L. serpyllifolia Dicks. from L. flava Sw. (1) The size is smaller 
and the colour more rarely yellowish; (2) the leaves rounder, and with 
a much longer and more turgid lobule, sometimes equalling half the leaf; 
(3) the cells larger (,4,™™ in diameter, against ~,—3,™™ in L. flava); (4) 
the underleaves variable in size, generally smaller than in L. flava, 
always cloven quite to the middle, and with the segments oftener acute, 
(although in some forms obtuse); (5) the perianths rather shorter, acutely 
5-carinate, (whereas in every form of L. flava the keels are very slightly 
raised, and obtuse). 
As to L. thymifolia Nees (Syn. Hep. 372), Gottsche admits it to be a 
composite species, as it stands in ‘Syn. Hepaticarum.’ Only the Javan 
and Indian specimens (he says) should be called by that name. The 
plant from Serra de Estrella (Brazil), gathered by Beyrich, is a form of 
L. pulvinata; and that from Madeira (perhaps also the Mexican plant) 
belongs to L. flava. (Mex. Leverm. 218.)—Whether there be, even in 
India, any “ L. thymifolia” distinct from L. flava is doubtful, for I have 
examined Javan specimens of the former, named by Nees himself, and 
could find no character to separate them.—The plant published as ZL. 
thymifolia N. by Mitten in Hooker’s ‘ Handbook of the N. Zealand 
Flora’ not only does not agree with the original description, but the 
specimens show it to be distinct also from L. flava and serpyllifolia. I 
have given its spec. char. above, and add here a few diagnostic marks:

serpyllifolia foliis fornicatis prelate ovatis—fere triangularibus—seepius

* The Eng. Bot. figure of ‘‘Jung. serpyllifolia,” t. 2537, April 1, 1813, 
made from specimens gathered at Killarney by Sir T. Gage, is so much more 
like L. flava than L. serpyllifolia that I suppose it may really be that 
species.
