230 MR. A. W. HILL—REVISION OF 
retusa, basi in tubum 5 mm. longum coalita. Carpella circa 8, fere matura, 6 mm. 
longa, rostris late subulatis 2 mm. longis, dorso breviter stellato-pilosa. 
Bortvia : Dep. La Paz, nerr Copacabana, felsite mountains, 4400 m., A4. W. Hill, 83; 
Dep. La Paz, near Huaycho, N.E. side of Lake Titicaca, stony hill-sides, 4. W. 
Hill, 84 (Herb. Kew.: Pl. 29. fig. 18). 
This species somewhat resembles JV. flabellata collected by Mandon. It differs, how- 
ever, in having the lamina much more deeply cut than is usual in that species (Pl. 99, 
fig. 18), in the tomentum of more silvery and shaggy stellate hairs, in the smaller calyx, 
and in the colour and form of the corolla. It is perhaps more nearly allied to the group 
containing N. pedicularifolia (q. v., p. 246). This plant was found on the dry stony hill- 
sides of the Copacabana peninsula on the S.W. side of Lake Titicaca and in a similar 
position on the N.E. side of the lake near Huaycho. As there is no record of this species 
from the main chains of either the Eastern or Western Cordillera, it seems possible that 
it may be confined to this small area, and may have spread from the Copacabana penin- 
sula to the N.E. side of the lake across the narrow straits of Tiquina or vice versá. 
25. NororRiCHE MacrEANII, A. W. Hill (desc. emend.).—Fruticulus depressus, czespitosus, 
pulvinatus; caudex subterraneus, lignosus, firmus, ramosus. Folia arcte aggregata, 
imbricata, incano-viridia ; petiolus 1:5-2 cm. longus ; stipulze petiolo supra medium 
adnate et cum eo quasi vaginam membranaceam formantes, parte libera lineari- 
spathulata membranacea 5-6 mm. longa, supra ad apicem lano-stellato-tomentosa, 
infra uti vagina (supra et infra) plus minusve glabra; lamina flabelliformis, 
palmatisecta, 5-6 mm. longa, 1:0-1:2 em. lata, supra lanato-stellato-tomentosa, infra 
subglabra, segmentis profunde trilobatis (segmento medio raro 5-lobato), lobis 
obovatis crenatis. Flores fere in petiolum medium insidentes, sessiles. Calys ultra 
medium 5-lobus, 1-5 em. longus, lobis lineari-lanceolatis acutis circa 9 mm. longis, 
extus sparse stellato-pilosus. Corolla czruleo-violacea, 3-3:5 cm. longa; petala 
obcuneata, retusa, basi in tubum vix coalita. Stamina in columnam cylindricam 
instructa, filamentis liberis elongatis. Carpella matura non visa, ut videtur breviter 
birostrata, dorso dense stellato-tomentosa.

p.380; Baker fil. in Journ. Bot. xxix. p. 364. 
Peru: High Cordillera, Maclean (Herb. Kew.: Pl. 29. fig. 13) ; Arapa near Yauli, 
above Hacienda, Lima-Oroya Railway, 4600 m., Weberbauer, 382; above Oroya, 
4300 m., Weberbauer, 1705 (Herb. Berol.). 
The corolla-tube is practically absent in this species and the stamens are arranged in à 
cylindrical head with fairly long free portions to the filaments. 
* This species is not in any way nearly allied to .N. pedicularifolia (v. Weddell, Chl. And. 
tine 280), but appears to show affinity to N. aretioides, though it is conspicuous and 
distinet with its large flowers. A figure of the leaf is given on Pl. 29. fig. 13.
