Ruta, Linn. From the Greek rute, from ruo, to 

 flow; probably in reference to some reputed quali- 

 ties of the plants ; hence the English word Rue ; 

 Linn. 8, Or. 1, Nat. Or. Rutaceaz. The spe- 

 cies of Rue are all of the simplest culture. 

 Any light rich soil suits them, and they are 

 readily increased by cuttings placed under a 

 hand-glass ; or by seeds, which are produced 

 in abundance by many of the species. Syno-

RtrYSCHlA, Jacquin. In honour of Fred. Euysch, 

 M.D., who published the "Hortus Amstelo- 

 damensis," a posthumous work of John Com- 

 melin : he died in 1731. Linn. 5, Or. 1, Fat. 

 Or. Marcgraaviacece. This very desirable 



shrub will succeed well in a mixture of loam 

 and vegetable mould ; and ripened cuttings 

 will root freely in sand, under a glass, in heat. 

 In Guiana and the Carihbee islands,it is a para- 

 sitical under-shrub, rooting on trees in moist 

 woods, similarly to the ivy with us.

SabbAtia, Adanson. In honour of L. Sabbati, 

 a celebrated Italian botanist. Linn. 5, Or. 1, 

 Nat. Or. Genlitmaccce. The species of this 

 genus are very handsome when in flower, and 

 are, on that account, deserving of a place in 

 every collection. The seeds, as soon as ripe, 

 should be sown thinly in pots, or on a shady 

 border, in peat soil ; if grown in pots, they 

 should be placed in shallow pans of water, as 

 the species are natives of marshes or bogs.

 name. Linn. 3, Or. 2, Nat. Or. Graminacem. 

 This genus is of very great importance, on 

 account of its containing the sugar-cane, S. 

 officinarum. The species are all of very simple 

 culture, in a light rich moist soil, with a good 

 heat ; and are increased by suckers, or cuttings 

 of the stem will throw out shoots at their 

 joints. See Eridnthus, Imperata, Ripldium, 

 and Tricholdma.
