This new species in habit and foUage is similar to P. Wattersii Hance, which, 

 however, is readily distinguished by its yellow flowers which are from 12 to 20 mm. 

 long and larger in all their parts. It is apparently the same as the plant referred 

 to P. Wattersii by Hance in 1882, though it is obviously distinct from his species 

 described in 1881. The Hupeh specimen which has slightly larger and thinner 

 leaves, slightly less abruptly acuminate than those of the type, was received from 

 Kew under the name P. Wattersii. Hemsley when founding his P. Mariesii {Jour. 

 Linn. Soc. XXIII. 61 [1886]) had not seen Hance's type of P. Wattersii, but only 

 the specimen from Kwangtung collected by B. C. Henry, and it is evident that 

 Hance's mistaken identification of this latter plant misled Hemsley. Chodat in 

 his monograph mistook A. Henry's No. 7114 from western Hupeh for B. C. Henry a 

 plant from Lien-chau, Kwangtung, and believing the latter to represent Hance s 

 species, described and figured it as P. Wattersii, To add to the confusion, the 

 two specimens referred by Hance to his P. Wattersii are mounted on the same 

 sheet of Hance's herbarium, now in the British Museum, and their labels seem to 

 have been transposed, for the detailed information sent us by Dr. A. B. Rendle 

 and supplemented by sketches and fragments show that the large-flowered speci- 

 men (the true P. Wattersii) is labelled " Lien-chau, B. C. Henry " while the 

 small flowered (our P. caudata) is labeled " Ichang, T. Watters." According to 

 Hance's description it is perfectly clear that he had the large-flowered specmien 

 before him when he described the plant collected by Watters near Ichang, the only 

 one he had seen in 1880, when he published his description, for the small- 

 flowered plant was not collected until the following year.
