Hairy though they are, the foregoing are not the most 

 hairy forms of specimens which have come to Europe. 

 Plate XXXVII shows a remarkable plant represented by 

 the single sheet photographed. It is in Kew Herbarium. 

 Hancock collected it under field number 114 on shady 

 limestone precipices at 6600 feet at Mengtz in December 

 1893. The right-hand specimen shows a normal obconica 

 rosette with leaf-petioles, margins of blades and under side 

 densely villous, the hairs being very darkly coloured and 

 the stout hairy scape bearing many flowers on long pedicels, 

 all being very hairy. The specimen on the left I take to be 

 a monster in which the flower-scape has forked, one branch 

 forming an umbel, the other a many-flowered bracteate 

 raceme. 



Of many other forms of divergence — great or small — 

 which the type P. obconica, Hance, shows, I shall indicate 

 a few which illustrate special features : — 



Plate XXXVIII shows a Yunnan plant which differs from 

 the type in the length of the petioles and is also nearly 

 glabrous. The leaves have a more coriaceous consistence 

 than the normal. The long scape has pedicellate flowers. 

 Note also the robust rhizome. 



Plate XXXIX is a Szechwan form which, with leaves of 

 about typical size, has the margin of the leaf-lamina broadly 

 crenate or dentate. It has a fair proportion of hairs over 

 the leaves. The umbel is profusely flowered, and the flower 

 itself, with long pedicel, has a stout corolla-tube. 



The Yunnan plant shown in Plate XL recalls in many 

 features P. filipes, Watt, but it is altogether a larger plant. 

 The short delicate scapes and the few-flowered umbels 

 bearing shortly pedicellate flowers smaller than usual are 

 marked characters. Further particulars observable in the 

 plant are : — 



Rhizomatous. Lamina ovate, 5 "5 cm. long x 4*5 cm. wide ; 

 somewhat thick ; paler below, upper surface glabrous ; 

 margin nearly entire only slightly crenate denticulate 

 ciliate. Petiole about equal to lamina, hirsute but not 

 densely. Scape slender curved equalling or barely exceed- 

 ing leaves ; delicately hirsute. Umbel 3-4-flowered ; bracts 

 minute linear with pedicels hirsute. Pedicels slender fili- 

 form short 7 mm. at most. Flower long-styled. Calyx
