and specimen A was labelled, in the first instance in the 

 Paris Herbarium, with the name given by Franchet, and it 

 comes from the same locality as B. Yet in his description 

 of the species Petitmengin quotes neither of them, but 

 cites the specimen which is the type of Franchet's var. 

 (c) glabrescens. The plant so described by Franchet is. as I 

 have already pointed out (see p. 333), P. sinciisteri, Balf. til. 

 The specimen cited by Franchet as the type is Franchet's 

 var. (b) rotv/ndifclia. Neither of Petitmengin's specimens 

 of P. begoniiforniis, Petitm., is P. sinolisteri, Balf. fil., nor 

 do the types of Franchet's variety (b) rotundifolia belong 

 to P. sinolisteri, Balf. fil. 



I suspect that the confusion introduced by Petitmengin 

 may be traceable to the fact that under No. 307 of Delavay 

 both Franchet's (6) rotundifolia and (c) glabrescens are 

 included. However this may be, the question I have to 

 settle for myself here is what nomenclature is to be 

 adopted. Had the name rotundifolia, been free, using it 

 would have simplified matters, but it is already taken for 

 Royle's beautiful Himalayan plant. The name P. bego<> ii- 

 formis, Petitm., might have been suppressed. I have 

 concluded to trust to Petitmengin's actual specimen deter- 

 minations rather than to his descriptive account and 

 reference to a mixed type, and have therefore retained his 

 name for the microform designated by Franchet (b) rotu ndi- 

 folia and shown in Plates XLIX, L, LI, LIT. 



On Plate LIU is shown a representation of the fcype- 

 specimen of a species of primula described by R. Knuth 

 under the name P. BonafH. Knuth. 1 I am indebted to 

 31. Bonati for the opportunity of examining and figurine- 

 the species. I give here Knuth's description of his 

 species : — 



" Perennis, 10-12 cm. alta. Folia paucinumerosa. 4-8: 

 petioli lj-3 cm. longi, crassiusculi, pilis articulatis olandu- 

 ligeris±rubellis hirsuti ; lamina firma vel fere subcoriacea, 

 ambitu ovata vel ovalis basi±cordata. usque 5 cm. lono-a et 

 4 cm. lata, subtus ad nervos subhirsuta, marline vix 

 repando-lobulato. Scapi plures, umbellam unicam con- 

 gestam gerentes, folia li-2i-plo. superantes, usque 10 cm.
