 VOL. ii. 114. 



wider. Stamina: filamenta three, united into a subtriquetrous 

 tube, shorter than the corolla, distinct at the top ; antheree 

 bifid below, fastened by the back. Pistil: germen obovate, 

 inferior ; style three-sided, length of the tube ; stigmas three, 

 thickish, awl-shaped at the top, erect. Pericarp : capsule 

 obovate, rounded, three-sided, three-celled, three-valved, with

 six, almost equal. Style : one. Capsule : three-celled, infe- 

 rior. The species are, 



1. Sisyrinchium Elegans. Scape round, one-flowered, 

 simple; leaf radical, linear, acuminate, shorter; petals oblong, 

 acute ; corolla yellow on the outside. Native of the Cape. 

 See the next species. / 



2. Sisyrinchium Collinum. Scape round, one-flowered, 

 simple ; leaf linear-acuminate, shorter ; petals oblong, acute. 

 This is very like the preceding species. Native of the Cape, 

 where it is very abundant. This, and the preceding, must 

 be kept in the dry-stove, and the other species in the bark- 

 bed. They may all be increased by the root. 



3. Sisyrinchium Grandiflorum ; Great-flowered Sisyrin- 

 chium. Scape round, simple, leafy ; spathe subtriflorous ; 

 petals obovate, obtuse ; leaves lanceolate, plaited. Root 

 bulbous. Native of Peru. 



4. Sisyrinchium Bermndiana ; Iris-leaved Sisyrinchium. 

 Scape ancipital, branched, leafy ; spathe subquadriflorous, 

 shorter than the flowers; petals mucronate ; leaves ensiform; 

 root fibrous, perennial. The stalk is terminated by a cluster 

 of six or seven flowers, on short peduncles, and enclosed in 

 a two-leaved keel-shaped sheath before they open ; they are 

 of a deep blue colour, with yellow bottoms, and are an inch 

 over when fully expanded. Native of Bermuda. This is a 

 tender plant, and requires the protection of a glass-case. 

 Both it and the next species are propagated by seeds, and 

 also by parting their roots ; if they are raised from seeds, they 

 should be sown in autumn soon after they are ripe, upon 

 an eastern aspected border, where they may have only the 

 morning sun : the best way will be to sow them in drills, at 

 three or four inches' distance, covering them about half an 

 inch with light earth. In the spring the plants will appear, 

 when their leaves have greatly the lesemblance of grass, and 

 therefore care should be taken that they are not pulled up as 

 weeds by those who till the ground. During the first summer, 

 they will require no other care but to keep them clean from 

 weeds, unless the plants should come up so close as not to 

 have room to grow ; in which case part of them should be 

 drawn out to give room to others, and these may be planted 

 in a shady border at three inches' distance, where they may 

 remain till autumn ; when they should be transplanted to the 

 places where they are to remain, and in the following sum- 

 mer they will flower. These plants prefer a shady situation, 

 and a soft loamy undunged soil. The time for transplanting 

 and slipping off the old roots is early in autumn, that they 

 may get good roots before winter. 



5. Sisyrinchium Anceps ; Narrow-leaved Sisyrinchtum. 

 Scape ancipital, winged, simple, almost leafless ; spathe sub- 

 quadriflorous, unequal, longer than the flowers ; petals mu- 

 cronate ; leaves eusiform. Root perennial, fibrous, from which 

 arise many very narrow spear-shaped leaves. The flowers 

 of this only expand for a short time in the morning, but the 

 others continue open the whole day. Native of Virginia, and 

 other parts of North America. See the preceding. 



6. Sisyrinchium Micranthum ; Small-flowered Sisyrinchium. 

 Scape ancipital, branched, leaf) ; spathe subtriflorous, une- 

 qual, nearly equal to the flowers ; petals linear, acuminate ; 

 leaves grassy, channelled. Native of Peru.
