 posed in a kind of umhel at the top of the peduncle. Flowers 

 white.

 spatulate ; peduncles 1 -flowered. J? . B. S. Native of Guiana, 

 in the island of Arowabisch, in sandy places inundated by the sea. 

 Flowers white. 



Creeping Crenea. Shrub creeping. 



Cult. Should either of the species of Crenea be ever intro- 

 duced to the gardens, we would recommend their being grown 

 in sand, kept moist by salted water, or the pots in which they 

 are grown may be placed in pans filled with salted water.

 guiculate, spreading. Stamens 8, approximating by pairs, which 

 alternate with the petals. Ovarium sessile. Capsule hardly 

 dehiscent, or a membranous berry, 4-celled, globose. Seeds 

 angular, numerous in the cells. A smooth shrub. Leaves 

 quite entire. Flowers white, disposed in panicles or corymbs. 

 Lamsonia acronychia of Lin. fil. or more properly Acronychia 

 lae'vis of Forster, is a genus that does not belong to this order. 

 It has been referred to Aurantiacece by Labillardiere in sert. 

 austr. cal. p. 66. 



1 L. A'LBA (Lam. diet. 3. p. 106.) leaves opposite, lanceo- 

 late, quite entire ; flowers in panicles. fy . S. Native of the 

 East Indies, Levant, and north of Africa, where it is frequently 

 cultivated in gardens. Cyprus of the ancients. Henna or Al- 

 henna of the Arabs. Alcanna, Humph, amb. 4. t. 17. Mail-

 Lin. spec. 4. p. 498. L. inermis, Desf. atl. 1. p. 325. Young 

 trees unarmed. Old trees having the branchlets hardened into 

 spines. Flowers white. The powdered leaves, made into a 

 paste, are much used by Egyptian women to dye their nails 

 yellow, which they esteem an ornament. The colour lasts for 

 3 or 4 weeks before there is occasion to renew it. The plant is 

 supposed to possess vulnerary and astringent properties.

 spinescerJ ; leaves elliptic-obovate, acute ; lobes of calyx twice 

 the length of the tube. Tj . S. Native of Banda. 



Scarlet Lawsonia. Shrub. 



Cult. The species of Lamsonia thrive well in a mixture of 

 loam and peat; and cuttings strike root readily in sand, with a 

 hand-glass over them, in heat.
