236 Transactions.— Botany. 
This, which is an exceedingly handsome plant, is at once distinguished 
from Myosotis (Exarrhena) macrantha by the more silky indumentum, colour 
of the flowers, and particularly by the shape of the corolla, which has a 
short tube and large deeply divided limb ; whereas in M. macrantha the tube 
is very long and the divisions of the limb comparatively shallow. From M. 
lyallii it is separated by the leaves, indumentum, calyx and corolla. 
In the Wairau Valley, Nelson, I have gathered immature specimens of à 
plant agreeing with this in the structure of the flowers, ete., but with the 
habit and foliage of M. saxosa. I am tempted to consider it a hybrid 
between the two species. 
8. Myosotis (Exarrhena) lata, n. sp. 
Stems slender, simple or sparingly branched from the root, hispid, erect 
or ascending, 6-12 inches high, sparingly leafy. Radical leaves variable m 
size, 1-3 inches long, linear- to obovate-spathulate or obovate-oblong, gradu- 
ally narrowed into long or short petioles, obtuse, rather thin, hispid on both 
surfaces with short white hairs. Cauline leaves smaller, sessile, lanceolate 
or oblong. Racemes terminal, elongate, hispid, many-flowered. Flowers 
on slender pedicels, white with a yellow eye, or altogether yellow. Calyx 
5-lobed to near the base, lobes narrow, erect, covered with simple or 
occasionally hooked hairs. Corolla rather large, $-} inch long, $ inch in 
diameter, nearly campanulate, tube short, limb with short, rounded lobes. 
Stamens with long filaments, the anthers nearly or quite exserted. Style 
exserted. Nuts ovoid, pale-brown, shining. 
Hab. Apparently not uncommon on the Nelson mountains, altitude 
2,000-4,000 feet. Red Hills, Wairau Valley; Mount Arthur Plateau ; 
Mount Owen, ete. T.F.C. 
In habit very close to M. australis, with which it has probably been 
confounded. It is usually smaller, more slender, much more sparingly 
branched, and not so hispid. The flowers are altogether different, being 
larger and more campanulate ; the anthers are on long filaments, so that 
they stand nearly on a level with the top of the corolla, and the style is 
altogether exserted. The nuts are also broader, and appear to be pale- 
brown when ripe. In the true M. australis the filaments are shorter than 
the anthers, which are included in the tube of the corolla, their tips just 
appearing above the scales ; and the style is hardly longer than the calyx. 
A plant common in many places in the Canterbury mountains, and 
which at present I include as a variety of M. australis, has a broad almost 
campanulate corolla nearly as large as that of M. leta. But the anthers 
and style are precisely those of M. australis.
