collected by Wilson under the same number (4033), of 

 which I think it worth while to introduce a photograph 

 (Plate XLIV), and I am able to do so by the kindness 

 of Dr. Rendle, Keeper of the Botany Department. The 

 specimen shows how, even in the same collecting, differ- 

 ences in the specimens occur. The plant in Plate XLIV 

 has the general aspect of that in Plate XLIII, but the 

 leaves are much more leathery and want the prominent 

 denticulations. Of these large-leaved short-scaped forms 

 a good example is furnished by the plant which has been 

 described as 



P. Petitmengini, Bonati. 1 (Plate XLV) 



The specimen which is figured in Plate XLV is the type 

 of this species. It is a rhizomatous multicipitate form. 

 The characters that arrest attention are : — The few leaves ; 

 the large lamina, which is membranous, nearly entire, and 

 has projecting veins ; the long white hairs ; the short 

 scape, very delicate ; the short membranous bracts ; the 

 long thread pedicels, nearly as long as scape ; the few 

 flowers in umbel, which as usual open successively and 

 therefore give unequal pedicels ; the very small calyx with 

 apiculate lobes ; the narrow corolla-tube. It has, as 

 Bonati says, a look of P. filijpes, Watt, but the plant is

" Species perennis, villosa. Folia longe petiolata, petiolis 6-8 cm. 

 longis, lanatis ; limbo integro, vel obscure lobato, basi cordato, ovato- 

 oblongo, obtuso, 7-9 cm. longo, 4-7 cm. lato, menibranaceo ; nervis

 multo brevior, 3-5 cm., erectus fistulosus. Bracteae 2-3 mm. lineatae, 

 obtusae vel acutae. Umbellae simplices, 3-5-florae. Pedicelli graciles, 

 inaequales, 10-25 mm. longi. Calyx infundibuliformis, baud accrescens, 

 3-5 mm. longus, superficialiter lobatus, lobis triangularibus, acutis. 

 Corolla calyce duplo longior, tubo cylindrico, 1 cm. longo ; limbo 

 concavo tubum aequante, 1*5-2 cm. diametiente, lobis 5 profundis, 

 usque ad tertium superiorem in 2 lobulos obtusos fissis. Capsula parva,

" Plant near P. filipes, Watt, from whicb it differs in its very large 

 leaves with the petioles shorter than the limb, by its few-flowered 

 umbels, the corolla with concave limb and bifid lobes. It has some 

 analogies with P. Vilmoriniana, Petitm., but is clearly distinguished by 

 its shorter scapes, by its leaves, its few-flowered inflorescence, and by its 

 much larger flowers."
