This is a very pretty species, though not quite so handsome as its near congener, M. alpestris, Schm., from which it differs at first sight in the smaller corollas, which are of a deep violet-blue, as in M. Azorica, H. Wats. It may I think be distinguished from any of the species of this difficult genus by the dense capitate racemes, together with the narrow calyces and calycine segments and the long tube of the corolla. Another allied species, the M. fulva, Hook. and Arn., which inhabits the west coasts both of extratropical North and South America, chiefly differs from this in the shorter tube of the white corolla, and in the calyces being densely covered with silky fulvous or pale brown hairs.

This is a very small species, typical of a high latitude and rigorous climate, preferring also those localities where few other plants but lichens and mosses can exist. It is remarkable as belonging to a small section of the genus, apparently confined to the islands of New Zealand, of which the M. spathulata, Forst., is the type. These have many of the lower flowers solitary in the axils of the uppermost leaves, and the true ebracteate raceme reduced to a very short and few-flowered spike.
The leaves of several of the New Zealand species of Boragineæ so closely resemble one another in form, that unless good flowering specimens are examined, two genera may easily be considered as belonging to one and the same plant. Such are a species of Exarrhena, Br., and the M. spathulata of A. Richard. The latter is a very distinct plant from either M. capitata or M. antarctica, as also from the true spathulata of Forster,
