3. G. spenceri, n.s. Plate XXVII. a and b. 



Annual ; stems erect, very slender, 3in.-7in. high. Leaves 

 rosulate, broadly ovate-spathulate, about lin. long, narrowed 

 into short petioles, obtuse or rounded at the apex ; cauline 

 leaves narrow oblong - spathulate, petiolate. Flowers in 

 2-4-flowered lateral or terminal involucrate umbels, pedicels 

 short. Calyx equalling or exceeding the narrow corolla, seg- 

 ments ovate-oblong, obtuse or subacute ; ovary sessile. Leaves 

 of the terminal involucre ovate, petiolate. 



Hab. South Island: Mount Eochfort ; 2,000ft.; Rev. 

 F.H. Spencer! (1880). 



I have only seen two specimens of this curious plant, both 

 of which are too far advanced to be quite satisfactory ; but, 

 after waiting fourteen years in the vain hope of obtaining 

 better material, I venture to publish it as a distinct species, 

 chiefly on account of the petiolate involucral leaves and 

 smalf flowers with calyx teeth fully equalling the corolla. 



4. Gentiana pleurogynoides, Griseb. Gen. et Sp. Gent., 

 236 (Emend.). 



Annual, erect, slender or robust, 6in.-18iu. high. Radical 

 leaves lin.-3in. long, petiolate, ovate-spathulate or oblong- 

 spathulate or lanceolate, obtuse or acute ; cauline few, 

 sessile. Flowers usually less than Un. diameter, in ter- 

 minal cymes or umbels. Calyx divided from one-third to 

 two-thirds of its length ; segments usually acute, divergent, 

 shorter than the corolla ; ovary shortly stipitate. D C, 

 Prodr., ix., 99; Hook, f., Handbook N.Z. Fl., 190. 



Hab. South Island. Common.
