grow. About the end of June they should be removed into the 

 green-house, where they will flower and seed. A few plants may 

 be planted out into a sheltered situation in the open border, in 

 order to ascertain whether the plant will grow in the open air.

 pedicels 1 -flowered, opposite the leaves. ^ . S. Native of the 

 West Indies. 



Opposite-flowered Thylachium. Shrub 8 feet. 



Cult. No species of this genus has as yet been introduced 

 into European gardens, but should they be, we would advise 

 that they should be treated in the same manner as the genus 

 Stephania, which see, p. 285. 



XX. HERMIT PO A (native name of the plant.) Lcefl. 

 itin. 307. D. C. prod. 1. p. 254.

 one tubular, interior one 4-sepalled, small. Petals 4, linear.

 tive of South America. Flower scarlet, f 



Laefling's Hermupoa-tree. Tree 20 feet ? 



Cult. This plant has not yet been introduced, therefore the 

 mode of cultivating and propagating it is not known ; but we 

 would recommend its being treated in the same manner as Ste- 

 phania. Seep. 285. 



XXI. M^RUA (Meru is the Arabic name of M. uniflbra.) 

 Forsk. segyp. 104. D. C. prod. 1. p. 254.

 ed, valvate in the bud ; throat crowned with petaloid scales.

 crown many-parted. Tj . S. Native of Senegal. 



Senegal Maerua. Shrub. 



Cult. These shrubs will no doubt thrive well in a mixture of 

 loam and peat, and cuttings taken from young wood will strike 

 root if planted in a pot of sand, placed under a hand-glass, in a 

 moderate heat. 



XXII. A'RSIS (from ap^e, arsis, elevation ; because of the 

 fruit being seated on a long pedicel within the calyx.) Lour. fl.

 deciduous sepals. Petals 5. Stamens numerous, seated on an

 china. 



Wrinkled-leaved Arsis. Shrub 5 feet. 



Cult. A mixture of loam and sand will suit this shrub well, 

 and cuttings will strike root if planted in a pot of sand, placed 

 under a hand-glass. 



ORDER XVI. RESEDA' CEjE (plant agreeing with Reseda 

 in some important characters). D. C. 



Calyx of 4-5-6 permanent segments, which are slightly 

 open in the bud, or rotate 5 -toothed, as in Ochradenus. Petals

 of the calyx, and alternating with them, usually fringed or 

 cleft, furnished with broad claws, and inserted at the base, of 

 the elevated, dilated disk. Stamens definite, 2 or 3 for each 

 petal, inserted in the disk ; they are rather connate at the 

 base. Anthers 2-celled, at first erect, at length incumbent, 

 and sometimes as if they were bursting outwardly ; cells 

 parallel, 2-valved, free at the base, the rest connate, open- 

 ing by a longitudinal suture ; the outer valve is largest. 

 Ovary trigonal, or tetragonal, pedicelled, with the pedicel 

 closely fenced by the connate base of the filaments. Style 

 none. Stigma 3-4-lobed, with the lobes equal in number to 

 the angles of the capsule, and alternating with them, spreadingj 

 2-valved; valves connivent, truncate, and papillosely -hispid at
