Primula Bonatii, Knuth, as a name for a primula must 

 be suppressed. 



A form of more character is that which has been 

 described as 



P. barbicalyx, C. H. Wright. 1 (Plate LIV) 



Here we have a plant from Mengtz in Southern Yunnan, 

 collected by Hancock, under field number 109, on lime- 

 stone crags at 8700 feet, and also by Henry (No. 10,512) 

 on cliffs at 7000 feet, which belongs to the very hairy 

 forms of the series. It is a dwarf with leaves smaller and 

 lobed a little more prominently than in the form figured in 

 Plate LY, but densely hirsute all over. The scapes are 

 quite short and the inflorescence is therefore buried in the 

 foliage, but the pedicels are long and somewhat filiform. 

 The calyx is distinct — apart from the density of the 

 barbation at its base — in the long and acute lobes at times 

 denticulate. It hardly approaches P. Listeri, King, as 

 Wright suggests. It is entirely an obconica form and 

 quite a distinct one. 



From Szemao I have specimens (Plate LV) of a plant 

 which may be regarded as an enlarged P. barbicalyx, 

 C. H. Wright, and more nearly approaching the hispid 

 form of P. obconica, Hance. It was collected by Henry 

 (No. 11,999) in mountain forests at 4000 feet. The leaves 

 are larger and have longer petioles than P. barbicalyx, 

 C. H. Wright. The scape is longer and carries a truss of 

 shortly pedicellate large flowers. The calyx is particularly 

 noteworthy. It is somewhat membranous with large acute 

 lobes which always have a fringe of white hairs and are, 



1 C. H. Wright in Kew Bulletin (1896), 24. The technical 

 description given by Wright is : — 



" Humilis, foliismembranaceis ovatis dentato-sinuatis ciliatis pilosis, 

 petiolo laminae aequilongo dense piloso, pedunculo brevi, floribus 2-5 

 umbellatine dispositis, pedicellis elongatis, calyce campanulato extus 

 (praesertim basi) pilis brunneo-purpureis vestito lobis 5 triangularibus, 

 corolla dilute lilacina longe tubulosa segmentis 5 bilobatis. 



"Habitat. — China: Yunnan, Mengtse, limestone crags at 8700 feet, 

 W. Hancock, 109. 



"Folia 1-1 j poll, longa, f-1 poll, lata ; petioli 1 poll, longi. Pedun- 

 culi 1 poll, longi vel breviores ; pedicelli 6-9 lin. longi. Calyx 2 lin. 

 longus. Corollae tubus 5 lin. longus ; limbus 6-8 lin. diam. 



" Resembling P. Listeri, King, but differing in having a smaller calvx 

 covered with long brownish-purple hairs and a large corolla."
