I have repeatedly exammed the two Tasmanian states o f this plant, and compared them with the Australian,
aiul with the 3f. Australia {Coccoloba Australh, Forst.) of New Zealand and Norfolk Island, and am in doubt
whether they should be regarded as three varieties or species. In the ‘ London Joiu-nal of Botany ’ I distinguished
the var. f l o f Tasmama as a new species, M. Gunnii, about whose specific distinctness Gunn has no doubts whatever,
but this Meisner has since imited with M. adpressa. In the New Zealand Flora again I united the New
Zealand and Norfolk Island plant with the M. adpressa, var. a, but these Meisner keeps distinct, relying chiefly on
the moi’e membranous leaves, more graceful habit, and fimbriated stigmata of the New Zealand plant, for distinguishing
them. Of these characters I cannot confirm that of the stigmata, and those of the habit and texture of
the leaf are o f little importance, but I would add the much more acuminate leaf, which is three-lobed in young
specimens, and smaller, less fleshy perianth. M'ith regard to the differences between tlie var. a and fl o f M. adpressa,
they are quite as marked, though I doubt their being o f specific value : Gunn well sums them up, in saying
rliat the M. adpressa is a maritime plant, with trailing stems, sometimes climbing for 6 feet or so over rushes, etc.,
and with round blunt leaves at the ends of tbe twisted branches, with somewhat revolute margins, and smaller
flowers and fruit; whilst the var. fl always grows in the richest soil, in dense, humid, shaded forests, ascending to
the tops o f lofty trees, and sending out long, straight shoots ; it has longer, acuminate leaves, and larger flowers
and fruit.

A very large European and Asiatic genus, of which some species occur in various other parts of the world,
and tbree or four in Australia. Some of these are as conspicuous as the “ Forget-me-not,” which belongs to this
genus. I have followed Alph. De Candolle in uniting Fxarrhena w ith Myosotis. The geuus is distinguished by its
quinquepai-tite or quinquefld calyx, salver-shaped corolla, with contorted lobes, and tlie throat closed by conniving
scales ; and by the four compressed, smooth and glabrous nucules, that are not perforated at the point o f insertion ;
all are erect or suberect herbs, with spreading or appressed, rather rigid hairs, spathulate radical leaves, and long,
bracteate or ebracteate, scorpioid racemes of rather small flowers, which often change colour w ith age. (Name from
/ivç, a mouse, and ovs, an ear ; from the appearance of the leaves.)

A very extensive European, Oriental, and Indian genus, o f which there are a few species in many other parts
of the world, and tbree or four in Austraha. As in Myosotis, tbc corolla is closed by scales, but it is distinguished
from that genus by the (generally liispid or echinate) nuts being much dejiressed and adnate along the back to a
central columnar receptacle. (Name from kvw . a dog, and yXwo-o-a, a tongue; in aUusion to tlie rough surface of
the leaves o f many species.)
