THE GENUS NOTOTRICHE. 259 
bipinnatifidis, supra plus minusve dense infra sparsissime sericeo-tomentosa, lobis 
integris vel 3-5-fidis, lacinulis ultimis numerosis anguste linearibus obtusis. Flores 
ad petiolum medium insidentes, brevi—2-3 mm.—pedicellati. Calyx supra medium 
5-lobis, 8-9 mm. longus, lobis triangulari-acutis vel acuminatis 3-4 mm. longis 
extus et ad margines sparse sericeo-ciliatis, tubo glabro. Corolla czruleo-violacea, 
14-17 cm. longa; petala obovato-cuneata, retusa, basi in tubum 4-5 mm. longum 
coalita. Stamina pauca in caput globosum instructa, filamentis liberis longis; 
anthers minute. Carpella circa 13, fere matura, birostrata, circa 4 mm. longa, 
dorso sericeo-ciliata, rostris circa 2 mm. longis. 
Peru: Crucero Alto, summit of Arequipa—Puno railway, 4470 m., 4. W. Hill, 82 
(Herb. Kew.: Pl. 29. figs. 9, 10). 
Distinguished from other species by its silky grey appearance and the numerous 
linear segments of the leaves (Pl. 29. figs. 9, 10). The stellate hairs are sessile and have 
only 2—4 long silky arms arising from each node. It is distinct from N. acuminata, 
particularly in the very small size of the anthers and in the distribution of the tomentum 
on the lamina.

Peru: Dep. Ancachs, Cordillera nigra supra Caraz, 4400-4500 m., Weberbauer, 
3103 (PI. 29. fig. 1) ; Prov. Cajatambo, Ocros ad Chonta, 4400 m., Weberbauer, 2777 
(Herb. Berol); without precise locality, Maclean (Herb. Kew.). 
A very distinct species, owing to the dense silvery coating of silky hairs all over the 
plant (Pl. 29. fig. 1). 
SPECIES IMPERFECTLY KNOWN. 
With regard to the following species considerable uncertainty exists. No specimens 
have been examined, and as the descriptions are not very concise and definite it seems 
best not to attempt to reduce them to other known species. 
SIDA PINNATA, Cav. Icon. v. p. 13, t. 422, fig. 1; DC. Prodr. i. p. 466. 
Sida pinnata, Cav., doubtfully of Presl, Rel. Henk. p. 111 ; doubtfully Malvastrum pinnatum, A. Gray, 
in Bot. U.S. Expl. Exp. p. 154; Wedd. Chl. And. ii. p. 281; Baker fil. in Journ. Bot. xxix. p. 365 
(Matthews, 682 exclus.). 
Ecvanor: in radicibus altissimis montis Chimborazo, ibique Sida phyllanthos, Cav. 
Although Cavanilles gives a figure of his species S. pinnata, it is not possible to be 
certain of his plant, owing to the lack of detail in the drawing. It seems unlikely that 
plants collected in Peru, near Lima, are of the same species as those from Ecuador ; and 
for this reason it seems best not to follow Gray, Weddell, and Baker fil., in placing 
either Gay's plant from the Cordillera of Cuzco or Pickering's plant from Casa Cancha 
Under this species. The form collected by Matthews from Cerro Pasco (no. 682), placed
