long, with short erect branches i inch high, bearing a few petiolate leaves and one or two large flowers. Leaves
petiolate, inch long, oblong, blunt, entire, smooth or hairy, blotched green and brown. Peduncles erect, with

A small genus, found in the mountains of India, the Malay peninsula and islands, and one species in Tasmania,
which also inhabits New Zealand. The M. Pumilio is an extremely variable plant in size of leaf and flower and
length of peduncle, and is smooth or hairy. Stems very short, rising from a long underground creeping rhizoma.
Leaves radical, inches long, linear, obovate-oblong or spathulate, blunt, entire or sinuate and toothed. Scapes
shorter or longer than the leaves, sometimes 5 inches long, one- to five-flowered, racemose or paniculately branclied ;
pedicels slender, 4 -lg inch long, erect, patent or recurved, each with a subulate bract beneath the flower. Calyx
campanulate, five-toothed, much shorter than the corolla. Corolla 4—| inch long, pale blue ; upper lip cuiwed back,
a little bifid; lower very large, three-lobed ; mouth with two swellings. Stamens four; anther-lobes spreading.
Style with two flat plates at the top. Capsule globose, compressed, blunt, loculicida).—A common plant in Tasmania;
always variable. (Name from fiados, a breast; from the swellings on the throat of the corolla.)

Generally extratropical herbs, and natives of North America ; a few are found in South America, Australia,
Tasmania, Asia, and one in Europe. Leaves opposite, entire, crenate or toothed. Mowers axillary, solitary,
sessile or pedunculate, generally two-bracteate below the five-partite calyx. Corolla with the upper lip bifid,
lower trifid. Stamens two, included (the other two reduced to subulate filaments or absent). Style dilated or two-
lobed at the apex. Capsule four-valved. (Name from gratia, grace ; from the medicinal properties of G. officinalis.)

H a b . Northern and Middle Islands, Banks and Solander, etc.
A rather fleshy herb, 6-8 inches long, quite glabrous, sparingly branched. Leaves opposite, ovate or oblong,
sessile, blunt ; with a few teeth towards the point, i inch long. Flowers 4 inch long, yellow, nearly sessile ; peduncles
sometimes elongated in fruit. Anthers two-celled, one cell sometimes empty.

H a b . Northern Island. Bay of Islands, B. Cunningham.
A smaller plant than G. sexdentata, and pubernlous, but not uniformly or constantly so : I find no other
difference between these two. Mr. Bentham observes that this entirely resembles G. Peruviana, except in the long
sterile filaments. G. pubescens is an Australian and Tasmanian plant.
