affinities being with T. nuda and its allies. Its flowers are very 

 small for the size of the plant, and its ovary long. 



II. In the summer of 1885 I received several specimens 

 of Tliehjmitra from Mr. Winkelmann, but from their being 

 long in transit, partly smashed up in passing through several of 

 our post-offices, and from their succulent nature and close- 

 packing half-rotten, I could make nothing of their flowers ; the 

 tubers, however, of some of them were uninjured, and I planted 

 them ; one, in particular, being loug and slender, I potted. This 

 summer (December, 1886) it produced the specimen here 

 described. I have closely examined three of its flowers in a 

 living state for their internal parts, and find them to correspond 

 closely. 



2. T. concinna, sp. nov. 



Plant small, stem 4| inches high, slender. Leaf single, 

 narrow, 3 inches long, thin, rather membranaceous. Flowers 2, 

 small, sub J inch diameter ; sepals ovate, acuminate, nerved, 

 brown ; petals blue with a tinge of purple, broadly ovate, apicu- 

 late, broader than lip ; column slightly hooded ; margins plain, 

 largely winged below; stammodia arising from a strong nerve, 

 long, curved, erect, finely filiform, with only a few long and free 

 hairs at tip, springing from 2-3 branches ; hairs reddish, clavate. 



Hub. Open country near the east bank of the River 

 Mohaka, north of Napier ; 1884: Mr. A. Hamilton. 



Obs. I regret that I have only had a single specimen of this 

 interesting little plant, which I believe to be a very distinct 

 species. Mr. Hamilton was also struck with its peculiar and 

 neat appearance when he gathered it, and though he sought 

 other specimens he was unsuccessful ; sheep being pastured 

 there in that locality, soon destroy all small tender indigenous 

 vegetation. Hitherto I have deferred publishing it, although I 

 had examined and noted its characters (as above) while fresh, 

 wishing first to obtain more specimens. Its small and graceful 

 appearance, thin leaf, blue petals, narrow lip, and few reddish 

 hairs springing in distinct bundles or branches from its stamiu- 

 odia, are peculiar characters. It is to be hoped that its 

 discoverer may meet with more of the same plant when again 

 in those parts. 



3. T. nervosa, sp. nov. 



Rather slender, straight, erect, 9-10 inches high ; a white 

 glossy sheath at base, 1 inch long, transparent, veined, trun- 

 cate, margin entire with a long narrow linear mucro ; 2 distant 

 sheathing cauline bracts each 1^ inches long, acute, adpressed. 

 Leaf single, 6 inches long, 3 lines wide, linear-acuminate, sub- 

 membranaceous. Scape very slender almost wiry at top, bearing 

 3 distant flowers ; floral bracts coloured, very broad, £ inch
