218 MR. A. W. HILL—REVISION OF 
Annue. 
1. NororRICHE PUSILLA, A. W. Hill, in Engl. Bot. Jahrb. xxxvii. 1906, p. 587. 
Peru: South, Feb. and April 1847, Weddell (Herb. Mus. Paris.: Pl. 29. fig. 19) ; 
Dep. Ancachs, Prov. Cajatambo, Cordillera nigra prope Chonta, 4400 m., Weberbauer, 
2788 (Herb. Berol.: Pl. 29. figs. 20, 21; Pl. 30. fig. 29). | 
The leaves are crowded in a terminal rosette ; short, spreading, horizontal branches 
are given off, which in their turn bear rosettes of leaves with flowers (Pl. 29. figs. 19-21). 
The tomentum is dense and somewhat shaggy, distributed all over the plant. The 
carpels have minute beaks (Pl. 30. fig. 29). 
9 NoroTRICHE PYGALEA, A. W. Hill—Annua pusilla, ezespitosa, circa 4 cm. longa; radix 
tenuis; caudex sub 1 em. longus, ramosus. Folia arcte aggregata, dense hirsuta ; 
petiolus 4 mm. longus; stipule petiolo ad medium adnat: et cum eo quasi vaginam 
minutam formantes, parte libera circiter 3 mm. longa subulata uti petiolus facie et 
in dorso stellato-tomentosa ; lamina reniformis vel subflabelliformis, circiter 2 mm. 
longa, 3 mm. lata, inciso-crenata vel lobata, lobis 8-10, supra et infra dense stellato- 
tomentosa. Flores ad petiolum medium insidentes, breviter pedicellati. Calyx ad 
medium 5-lobus, circiter 4 mm. longus, lobis triangularibus dense tomentosis, undique 
sparse tomentosus. Corolla albo-plumbea, 3 mm. longa; petala obovata, basi in 
tubum circiter 1 mm. longum coalita. Carpella 7, rotundata, circiter 1 mm. longa, 
ad apicem minute stellato-hirsuta ; semine reniformi omnino repleta.

Malva pygmea, Wedd. Chlor. And. ii. p. 274. 
Malyastrum pygmeum, A. Gray in Bot. U.S, Expl. Exp. p. 150, in adnot. ; Baker fil. in Journ, Bot. 
xxix. 1891, p. 167. 
Bonrvi: Laguna de Potosi, D'Orbigny, 1359 (Herb. Mus. Paris.: Pl. 29. figs. 22- 
24; Pl. 30. fig. 30). 
The whole plant of this species is only about 4 cm. long (Pl. 29. fig. 22), and the 
leaves are so small and so densely hairy that it is difficult to see how deeply the lamina 
is lobed (Pl. 29. fig. 23). The fruit is without a beak and is entirely occupied by the 
reniform seed (Pl. 30. fig. 30). The small flowers (Pl. 29. fig. 24) appear to be white 
with a dark centre, and on D'Orbigny's label are described as “ chiquito de flor blanca." 
This species and JN. pusilla are the only two known annuals in the genus. 
Perennes. 
3. NorOTRICHE CLANDESTINA, A. W. Hill.—Fruticulus depressus, ceespitosus, sepius 
pulvinatus; caudex lignosus, firmus, ramosus. Folie arcte aggregata, luteo- 
tomentosa ; petiolus circa 9 mm. longus; stipule petiolo plus minusve ad petiolum 
medium adnatz et cum eo quasi vaginam membranaceam 2 mm. latam formantes, 
parte libera 5-7 mm. longa filiformi uti vagina facie glabra in dorso et ad margines
