LINN^AN NATURAL SYSTEM. 



ORDER XLII. VERTICILLATS. 



43. The order verticillatse consists of herbaceous 

 vegetables, having four naked seeds, and the flowers 

 placed in whorls round the stalk. Hyssopus or hyssop, 

 lavendula or lavender, galeopsis or dead nettle, and 

 others. 



There is much difficulty in defining the limits of this order, but 

 Linnseus has divided it into two sections according to a character of 

 the calyx. The first section comprehends such as have a five-cleft 

 calyx, that is, where all the teeth of this part are nearly of equal 

 size and shape. The second consists of those with a two-lipped 

 calyx, which is indeed five-cleft, but its two upper segments are, in 

 a manner, united into one, which might almost be termed emargi- 

 nate only; while between these two united segments, and the re- 

 maining three, there is so deep a fissure at each side, that the calyx 

 is nearly divided into two parts or lobes. 



ORDER XLIII. DUMOSjE. 



44. The Dumosae from dumus, a bush, are all of the 

 shrub and tree kind, thick and bushy, rising from six to 

 thirty, and even forty feet high. Rhamnus or buckthorn, 

 sambucus or elder, viburnum, cassine, &c. 



ORDER XLIV. SEPIARIJE. 



45. Sepiariae from sepes a hedge, theplantsof which, 

 from their use and habits are particularly calculated for 

 hedges. Ligustrum or privet, olea or olive-tree, syringa 

 or lilac, &c. 



Leaves opposite, with scarcely any evident stipules. Flowers 

 dispnsed in a more or less dense panicle ; calyx four cleft ; corolla
