236 Transactions. — Botany. 



This, which is an exceedingly handsome plant, is at once distinguished 

 from Myosotis (Exarrhma) 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 a 

 plant agreeing with this in the structure of the flowers, etc., but with the 

 habit and foliage of M. saxosa. I am tempted to consider it a hybrid 

 between the two species. 



3. Myosotis (Exarrhena) lata, n. sp. 



Stems slender, simple or sparingly branched from the root, hispid, erect 

 or ascending, 6-12 inches high, sparingly leafy. Eadical leaves variable in 

 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. Eacemes 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, -J— | 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. Eed Hills, Wairau Valley; Mount Arthur Plateau; 

 Mount Owen, etc. 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. lata. But the anthers 

 and style are precisely those of M. australis.
