flower, shorter than the tube, linear, the outer ones broader, 

 almost lanceolate. Tube somewhat curved, slightly downy, 

 limb spreading, waved, unequally five-lobed, the margins 

 more or less recurved, at first yellow with an orange eye, 

 then becoming rose-coloured with an orange eye, finally 

 entirely rose-coloured. Calyx small, obscurely four-lobed. 

 Stamens four, inserted nearly at the middle of the tube. 

 Filaments short. Anthers rounded, brown. Pistil: Ger- 

 men ovate : Style about half the length of the tube : Stigma 

 capitate, oblique. 



Our Glasgow Botanic Garden is indebted for this hand- 

 some and most desirable inhabitant of the stove to Mr. 

 Marnocr, of Britton Hall, by whom it was communicated, 

 under the very appropriate name of L. mutabilis. The 

 comparatively large heads of flowers are at first wholly 

 yellow, with a deeper eye; the outer ones then first gra- 

 dually become rose-coloured, the orange eye for a time 

 remaining, when that changes likewise, and at length the 

 whole flowers are a delicate rose colour. Of what country 

 it is a native, I am ignorant; but it possesses all the essen- 

 tial character of L. nivea, and hence I have considered it 

 as a variety of that species, although, perhaps, the white- 

 flowered state should rather be considered a variation from 

 this. L. nivea is stated in Bot. Mag. t. 1946, to be an 

 East Indian plant; — a native of the West Indies according 

 to Sir J. Smith, in Rees's Cycl. From L. aculeata it 

 differs in its far more strongly aculeated and glabrous stems 

 and branches. Its flowers appear in May and June, and 

 continue for a considerable length of time.
