BonrviA: Bang, 1964, 1 (Herb. Kew.; Herb. Berol.). 
This species is characterised by the ashen-grey tomentum of fine stellate hairs which 
covers all the green parts of the plant. Two species were sent out under the no. 1964, 
Bang, the other being N. Mandoniana. 
N. cinerea agrees closely with both N. Mandoniana and N. anthemidifolia as regards 
the form and lobation of the lamina, but differs in the character and distribution of the 
tomentum.

subterraneus, lignosus, firmus. Folia rosulatim disposita, incano-sericea ; petiolus 
2-3 cm. longus; stipule petiolo infra medium adnate et cum eo quasi vaginam 
membranaceam 4-5 mm. latam formantes, parte libera membranacea lineari- 
lanceolata acuta 5 mm. longa, uti petiolus facie sericeo-ciliata in dorso glabra; 
lamina ambitu triangularis vel cordata, bipinnatifida, circiter 1:0-1:2 em. longa, 
1:0-1-2 em. lata, supra sericeo-tomentosa, infra glabra, segmentis infimis 3—-5-lobis, 
superioribus 3-lobis vel integris, lobis lineari-oblongis obtusis. Flores infra petiolum 
medium insidentes. Calyx ad medium 5-lobus, lobis triangulari-acuminatis, 
7-9 mm. longus, tubo glabro, lobis glabris vel pilis sericeis paucis instructis. 
Corolla rosea, 17-2:0 em. longa; petala obovata, retusa, basi in tubum 5-6 mm. 
longum coalita. Stamina in caput globosum instructa, filamentis liberis longis. 
Carpella 3 mm. longa, breviter birostrata, dorso ciliata, pilis 4 mm. longis. 
Peru: Andes of Ayacucho, 3600-4000 m., R. Pearce (May, 1867); Cordillera de 
Puno, Lechler, 1713 (Herb. Kew.). 
This species in some respects resembles N. anthemidifolia, but differs especially in 
the triangular outline of the lamina and in the long soft silky hairs of the upper 
surface. 
Hairs of this type are found also in N. argentea and in N. sericea. To this latter 
species N. acuminata appears to be very closely allied. 
61. NorOTRICHE SERICEA, A. W. Hill.—Fruticulus depressus, ceespitosus; caudex sub- 
terraneus, lignosus, firmus, ramosus. Folia rosulatim disposita, incano-sericea ;

subulato-filiformi circa 1 cm. longa, uti vagina facie et ad margines dense sericeo-

glaber; lamina ambitu triangulari-ovata, palmatifida, segmentis pinnatifidis vel
