 p. 77. Azorella species, Lam. Bolax species, Spreng. Koch. 



LIN. SYST. Pentdndria, Digynia. Margin of calyx 5-toothed, 

 permanent. Petals oval, entire. Styles short. Fruit ovate, 

 contracted at the raphe, and rather compressed from the back ; 

 mericarps semi-ovste, without any ribs or vittae ; ribs filiform, 

 hardly conspicuous. Humble tufted herbs, natives of Magellan. 

 Leaves imbricate, entire or trifid, with the petioles sheathing or 

 dilated. Umbels nearly sessile, 2-8-flowered ; pedicels about 

 equal in length to the involucrum. Perhaps this genus is hardly 

 distinct from Frtigosa. 



1 A. AR.ETIOIDES (Willd. herb, ex D. C. prod. 4. p. 77.) leaves 

 imbricate, tripartite, coriaceous ; lobes oblong, acutish ; petioles 

 thick and rather corky, villous at the apex ; umbels nearly ses- 

 sile, simple, 4-flowered ; leaves of involucrum 4, equal in length 

 to the pedicels. 1(L. F. Native of Quito, on the high moun- 

 tain of Antisana. Fragosa aretioides, H. B. et Kunth, nov.

 f. 1.) leaves imbricate, sheathing at the base, trifid, coriaceous ; 

 lobes subulate, acute ; sheaths funnel-shaped, ciliately toothed ; 

 umbels almost sessile, 2-3-flowered ; leaves of involucrum 2, 

 serrated. l/.F. Native of the Maclove or Falkland Islands. 

 D'Urvil, fl. mal. p. 47 This is a very different plant from

 chamitis, Pers. ench. no. 3. D'Urv. fl. mal. p. 46. Bolax 

 filamentosus, Spreng. in Schultes, syst. 6. p. 359. There are 

 varieties of this plant with either an elongated or crowded habitj

 ones 1 -flowered. Perhaps the same as Chamitis integrifdlia, 

 Gaertn. fruct. t. 22. f. 4.

 bot. misc. 1. p. 325. t. 63. Root long, descending. Plant 2

 which is gathered by the natives, and employed by them in the 

 cure of headache.

 chon. A. crassifolia, Pers. ench. 1. no. 2. Fruit ovate ; having 

 the mericarps furnished with 3 slender stripes on the outside, as 

 in the genus Fragosa. 



Tufted Azorella. PI. | foot. 



6 A. PAUCOI V DES (D'Urv. fl. mal. p. 45.) leaves all radical, 

 long, pinnate ; segments or leaflets remote, opposite, short, pin- 

 natifid : lobes alternate, acutely cut ; scapes short, very hairy ; 

 involucrum 8-10-leaved; fruit glabrous, striated, nearly sessile. 

 i;. F. Native of the Straits of Magellan, along the rivulet 



called Bougainville River. Root thick, fusiform. Umbels 3-8- 

 flowered. Leaves hardly an inch long, but still longer than the 

 scape.

7 A. RANU'NCULUS (D'Urv. fl. mal. 1. p. 46.) stem stoloni- 

 ferous, very short ; leaves on long petioles, 5-parted ; partitions 

 3-lobed at the apex, obtuse ; umbels axillary, on short pedun- 

 cles ; leaves of involucrum 5, lanceolate, acute, ciliated at the 

 base, about equal in length to the flowers. If. . F. Native of 

 the Straits of Magellan, along with the last. Habit of a small 

 Hydrocotyle or Ranunculus. Fruit round, hardly pedicellate, 

 crowned by the calycine teeth. Umbels 4-6-flowered. Petals 

 greenish yellow.

XIII. PECTOPHYTUM (from ,n,m>c, pektos, compact, 

 and tivrov, phyton, a plant; a compact tufted plant). H. B. et 

 Kunth, nov. gen. amer. 5. p. 28. D. C. prod. 4. p. 78. 



LIN. SYST. Pentdndria, Digynia. Margin of calyx entire. 

 Petals unequal, acute, and a little inflexed at the apex. Styles 

 short, straight. Fruit ovate-elliptic ; mericarps rather convex 

 on the back, semi-oval, 5-ribbed, without any vittae ; ribs fili- 

 form ; commissure flattish. A tufted herb. Leaves crowded, 

 imbricate, coriaceous, trifid, glabrous ; petioles permanent. 

 Flowers white, in crowded fascicles at the tops of the branches, 

 and solitary in the axils of the bracteas, pedicellate. Bracteas 

 ciliately toothed. This genus is allied to Bolax and Fragosa, 

 but it differs from the first in the form of the fruit, and from the 

 last in the margin of the calyx being entire.
