derived from the receptacle. There are but few species of 

 this section, all of which are Eastern European or Western 

 Asiatic. Of this the only one that approaches M. dissiti- 

 ilora is M. amwna, Rupr., a native of the Caucasus, which 

 has similar rooting habit, foliage, indumentum and long 

 pedicelled flowers, but these are very small, and in the 

 absence of nutlets I am unable to say whether ^ or not 

 M. amoena (published by Boissier, U F1. Orient.," iv. 241) 

 ten years later than dissitiflora, may not be referable to 

 this species. Should this prove to be the case, it would 

 follow, that if brought from Switzerland, itmust have 

 been from a garden. 



The effect of long cultivation of M. dissitiflora has 

 resulted in a very great enlargement of the whole plant, 

 and of the corolla in particular, from about a quarter of an 

 inch in the specimens preserved in the Kew Herbarium at 

 the date of the publication of the species, to that shown in 

 our plate. The latter represents a very luxuriant form, 

 received at the Royal Gardens from E. J. Lowe, Esq., 

 E.R.S., of Shirenewton Hall, Chepstow, who desires that 

 it should commemorate the interest in horticulture taken 

 by Mrs. Thiselton-Dyer, who, during her visits to the 

 Alps, has contributed many rare and interesting plants to 

 the Royal Gardens. 



Descr. — A rather straggling branching biennial or 

 perennial, sparsely clothed all over with soft, erect, or sub- 

 erect hairs. Lower leaves petioled, one to two inches 

 long, elliptic or spathulate, acute or apiculate, narrowed 

 into a petiole an inch long or more ; upper leaves sessile, 

 oblong, or ovate-oblong. Racemes elongate, slender, laxly 

 many-fld. ; pedicels one half to one inch long, sub-erect. 

 Calyx one-sixth of an inch long, tube short, and lanceo- 

 late segments clothed with erect straight hairs. Corolla- 

 tube about as long as the calyx, mouth hairy within ; limb 

 one-fourth to upwards of half an inch broad, flat, lobes 

 rounded, sky-blue, yellow at the mouth. Anthers with 

 the connective terminating in a blunt process. Nutlets 

 ovate, acute, dorsally convex, obscurely keeled, black, 

 shining, provided at the base with a short, stout, white 

 pedicel. — J. D. H.
