 Hab. In Himalaya temperata oceidentali frequentissima, a Nepal ?, Wal- 

 lich; ad Marri ! alt. 6000-8000 ped., Fleming (fl. Jul.-Sept.). (v.v.) 

 Species insiignis, gigantea, 4-10-pedalis, ramosa, caulibus basi crassitie 

 pollicis, fistulosis ?. Folia valde varia, longe v. brevius petiolata, basi 

 rotundata v. angustata, grosse serrata ; caule ad basin petioli glandulis 

 crassis pedicellatis aucto. Pedunculi robusti, stricti, erecti, 2-5",

This fine species approaches very closely indeed to some states of /. 

 longicornu. Wall., I. sulcata, Wall, (gigantea, Edgw.), I. Thomsoni, and 

 other allied species or varieties of Section H, but may always be known 

 by the shortly clavate capsule. This short clavate capsule is indeed 

 the only character by which many dried specimens can be distinguished 

 from I. longicornu and others of that section. 



The I. moschata of Edgeworth may be a different species, as Mr. Edge- 

 worth suggests, but I cannot distinguish it by herbarium specimens. 

 It is said to differ from I. Roylei in its musky odour, in its habit, and in 

 the leaves being more deeply serrate ; the latter appears to be a very 

 variable character, the upper leaves being more deeply cut than the 

 lower in both forms.

 superioribus alternis verticillatisque ovato- acuminatis petiolatis glan- 

 duloso-stipulatis grosse duplicato-serratis, pedunculis aggregatis elon- 

 gatis erectis pedicellatis subumbellatis racemosisve, bracteolis subu- 

 lato-lanceolatis, floribus ^-|" long, sordide lilacinis maculatis, sepalis 

 parvis ovato-lanceolatis, labello conice saccato in calcar breve rectum 

 attenuato, capsulis inclinatis I" long, lineari clavatis. 



Hab. Himalaya temperata subalpina, Sikkim, alt. 12,000 ped. ! J. D. H. ; 

 Kumaon et Garwhal, 12,000 ! St. Sf W. (6, 7, 8) ; Piti ! et Kunawur, 

 9000-10,000 ped. ! T. T. (fl. temp. pluv.). (v.v.) 



Ilerba robusta, pedalis et ultra, /. sulcata var. /3 similUma, sed omnibus 

 partibus minor, calcare breviore recto conico, sepalis angustioribus 

 capsulisque brevioribus. 

 This puzzling plant occurs throughout the Himalaya, on the edge 



of the Tibetan climate, and in subalpine districts. It differs from /.
