6 BALFOUR—NEW SPECIES OF PRIMULA. 
This is one of the southern forms of the widespread type 
of P. denticulata, Sm. and a very distinct one it is. Its small 
rosette of obovate puberulous leaves, from which a scape of 
great length for the size of the rosette ascends, gives it a well- 
marked character. The rhizome forms several rosettes, and 
there may be several scapes ascending from the same tuft. Its 
calyx has a curious membranous inflated appearance in dried 
specimens. It is the Chinese representative of the Himalayan 
P. erosioides (Watt), Balf. fil. et W. W. Sm. 
+ Primula annulata, Balf. fil. et Ward. 
Pusilla efarinosa rhizomate tenui ramoso late repente vestigiis 
foliorum vetustorum obtecto. Folia puberularosulata ad 1.5 cm. 
longa 5mm. lata spathulata vel oblongo-spathulata obtusa mar- 
gine regulariter serrata vel serrato-lobata deorsum sensim in 
petiolum alatum lamina longiorem evaginantem attenuata. 
Scapus ad 3.5 cm. altus gracilis uniflorus puberulus; bracteae 
duae parvulae puberulae virides lanceolatae subulatae alternae 
superior major ad 2.5 mm. longa ; pedicellus erectus ad 3.5 mm. 
longus puberulus ; anthopodium parvum. Calyx 3.5 mm. longus 
campanulatus viridis puberulus ultra medium fissus lobis 
triangularibus vel oblongo-deltoideis obtusis vel acutis nunc 
obscure dentatis ciliatis. Corollae violaceae tubus ad 4 mm. 
longus calycem triente vel quadrante superans supra stamina 
ampliatus extus erubescens intus ad orem minute puberulus 
annulo prominulo lobato instructus, limbi discus puberulus 
brevissimus, lobi ad 3 mm. longi obcuneati ad medium divari- 
catim bipartiti. Stamina filamentis brevissimis antheris 0.5 mm. 
longis in flore longistylo ad medium tubi corollini inserta calyce 
inclusa. Ovarium sphaeroideum; stylus longus vix calyce 
longior stamina paullo superans. Capsula oblonga calyce vix 
aucto omnino inclusa ; placenta columnaris. 
Species pusilla aspectu P. ywnnanensts, Franch., et P. bellae, 
Franch., sed ab hac oris barbati inopia ab illa corollae prominulo 
annulo recedit. 
-W. Yunnan. A-tun-tsu. Ona limestone peak, 14,000 ft. - 
June 1913. FF. Kingdon Ward. No. 511. In Herb. Edin. 
Two or three plants collected by Ward under the number 511 
but without further designation are all that we have of this 
distinct species. The habit of the specimens shows that the 
plant is one of mossy loose soils such as we associate with P. 
membranifolia, Franch., P. yunnanensis, Franch., and like forms. 
The delicate rhizome branches are closely invested with the 
brown dry leaves of previous years. The small flower with a 
distinct prominent annulus not barbate is a characteristic 
feature of the plant.
