 twining, pubescent ; leaves all petiolate, opposite, cordately- 

 sagittate, acuminated, with rather lobed margins : the lobes

Sagittate-leaved Loasa. PL tw.

 much elongated, nearly simple, shining ; leaves remote, oppo- 

 site, petiolate, cordate at the base, 5-7-lobed ; peduncles axil-

 lobes broadly ovate, shorter than the petals, which are red ; fruit 

 hemispherical. H. Native of Chili, about Coquimbo. 



Elongated-stemmed Loasa. PL 2 to 3 feet. 



7 L. PROSTRA'TA (Gill. mss. ex Arnott, in Cheek, edinb. journ. 

 3. p. 274.) stems prostrate, flexuous ; leaves opposite, sessile, 

 cordate, ovate, deeply angular ; peduncles axillary, 1 -flowered, 

 about twice the length of the leaves ; calycine lobes lanceolate, 

 longer than the fruit, and about equal in length to the petals ; 

 valves of capsule closely beset by long, rigid hairs ; seeds egg- 

 shaped, large, with a smooth testa. Q. H. Native of Chili, 

 on La Cuesta de los Manantiales, Cerro de San Pedro Nolasco, 

 &c. Plant covered with long, rigid, stinging hairs. 



Var. ft, Cumingii (Hook, et Arnott, in bot. misc. 3. p. 239.) 

 segments of leaves bipinnatifidly and sinuately toothed. About 

 Valparaiso, and on the mountains near Aconcugua. In the spe- 

 cies the segments of the leaves are simply and sinuately toothed. 



Prostrate Loasa. PL prostrate. 



8 L. FA'LLIDA (Gill. mss. ex Arn. in Cheek, edinb. journ. 3. p. 



274.) epidermis of stem loose, and shining ; leaves opposite, all pe- 

 tiolate, ovate, coarsely toothed ; panicles opposite, axillary, much 

 longer than the leaves ; pedicels short, in the forks, about equal 

 in length to the flowers ; calycine lobes linear-oblong, one half 

 shorter than the petals. Q. H. Native of Chili, among loose 

 debris, on the banks of the El Rio del Yeso, near Arroyo de 

 San Nicholas, at the elevation of about 5000 feet, &c., where it 

 is called by the inhabitants Cavalluna. The plant is most nearly 

 allied to L. sclarecefblia, Juss. but that does not appear to have 

 the loose epidermis on the stem, and the leaves are much larger. 

 The pedicels in the forks of the panicle are elongated. 

 Pale Loasa. PL prostrate. 



9 L. LATERiriA (Gill. mss. ex Arnott, in Cheek, edin. journ. 

 3. p. 275.) stems almost wanting; leaves opposite, on long pe- 

 tioles, pinnate ; segments roundish, crenated, lobed ; peduncles 

 twin, 1 -flowered, terminal, about equal in length to the leaves ; 

 calycine lobes oval, exceeding the tube, but one half shorter than 

 the corolla. Q. H. Native of Chili, at Los Imposibles, near 

 the foot of the descent from the Planchon towards Chili, and in 

 El Valle de Tray Carlos, at the base of the volcano of Pateroa, 

 at an elevation of 9000 feet. This species is readily distin- 

 guished by its large flowers of a brick red colour, and by its 

 very short stems and radical branches, each of which bear 1 or 

 2 pairs of opposite leaves, and between the upper pair of which 

 arise 2 1-flowered peduncles, terminating the branch. Seeds 

 with a strongly reticulated testa like the next species ; and as in 

 it the hairs are short and not stinging. 



JJn'c/c-coloured-flowered Loasa. PL prostrate. 



10 L. PINNATIFIDA (Gill, mss. ex Arnott in Cheek, edir.b. journ. 

 3. p. 275.) stems nearly erect; leaves opposite, on long petioles : 

 radical and lower ones pinnate : segments pinnatifid, with round- 

 ish approximate lobes ; upper leaves pinnatifid ; peduncles axil- 

 lary, usually 1-flowered ; calycine lobes ovate, much shorter 

 than the corolla, and half the length of the fruit. Q. H. Native 

 of Chili, at La Cuesta del Inga, at an elevation of about 9000 

 feet. Plant with short rigid, but not stinging hairs. 



Pinnatijid-leaved Loasa. PL 1 foot. 



11 L. DISSE'CTA (Hook, et Arn. in bot. misc. 3. p. 240.) stem 

 erectish, strong, a little branched at the apex, with a loose white 

 epidermis ; petioles opposite, lower ones elongated, becoming 

 gradually shorter to the top of the stem ; leaves tripinnatifid, 

 with the ultimate segments ovate-obtuse ; pedicels short, rising 

 from the forks of the stem ; calycine lobes narrow-oblong, not 

 half so long as the petals. Q. H. Native about Valparaiso, 

 Los Ogos de Agua, and Aconcugua. 



Dissected-leaved Loasa. PL I foot. 



12 L. HETEROPHY'LLA (Hook, et Arn. in bot. misc. 3. p. 228.) 

 stem prostrate, dichotomous ; leaves opposite, on short petioles ; 

 lower ones small, hastately triangular, coarsely toothed : lower 

 floral ones nearly reniform, 5-lobed, with the lobes nearly equal, 

 and furnished with 1 or 2 teeth each ; but the middle lobe of the 

 uppermost leaves is rather lengthened ; peduncles in the forks 

 longer than the leaves ; calycine lobes oblong-lanceolate, about 

 equal in length to the petals ; fruit conically hemispherical. Q. 

 H. Native about Valparaiso ? and at Los Ogos de Agua. The 

 stem is rarely pubescent ; but the branches, particularly in their 

 upper part, and the turbinate tube of the calyx, are provided 

 with long sharp spreading hairs. 



Variable-leaved Loasa. PL prostrate. 



13 L. ACANTHIFOLIA (Lam. diet. 3. p. 579.) leaves cordate at 

 the base, pinnatifid ; lobes acuminated, sinuately toothed ; pe- 

 dicels axillary, and also from the forks, solitary, 1-flowered; 

 lobes of calyx narrow, acuminated, reflexed, equal in length to 

 the petals, which are bidentate. O- H. Native of Chili. Juss.
