all respects closely resembled a catalpa. It is readily propagated by 

 cuttings of the roots or shoots ; flowers vigorously in any common soil, 

 tolerably dry, and will doubtless speedily become as common as the catalpa 

 throughout Europe. Horticultural Society's Garden. 



Order LV. LABLVCE.E. 



Ord. Cmar. Calyx tubular, persistent, 3-cleft or 3 10-toothed, regular, or bi- 

 labiate. Corolla tubular, bilabiate ; the upper lip undivided or bifid, and the 

 lower one trifid. Stameiis 4, didynamous, 2 of which are often sterile, inserted 

 under the sinuses of the lower lip. Lobes of anthers usually divaricated. 

 Ovaria 4, naked, seated on a glandular disk, and connected with the base 

 of the style. Stigjna\y\Sid. J67ze?'a 4, or fewer. Albumen \yantmg, or s'pa.vmg. 

 The opposite leaves, free 4-lobed ovarium, bilabiate corolla, aiui 

 didynamous stamens distinguish this order from i?oraginece ; and the 4-lobed 

 ovarium separates it from Ferbenaceas and ^canthaceae, &c. {G.JDun.) 



Leaves simple, alternate, exstipulate, evergreen ; small, crowded. Flowers 

 axillary or terminal. Low shrubs, for the most part so small as to be 

 treated as herbaceous plants ; natives chiefly of the South of Europe. ^ 



Though there are a number of genera belonging to this order containing 

 species which are technically ligneous, yet there are none that can popularly 

 be considered as shrubs fit for an arboretum, with the exception of Phlomis 

 fruticosa, i?osmarinus officinalis, Lavandula iSpica, and Salvia officinalis 

 these plants are so well known, that we consider it unnecessary to do more 

 than give figures of them, with the following slight notices: 



Flilomis fndicosa L (N. Du Ham., 6. t. 40.; Bot 

 Mag,, t. 1843. ; and oar fig. 1.309.), Jerusalem Sagei 

 is a native of Spain, with yellow flowers, appear-j 

 ing in -June and July. This is a greyish evergreert 

 shrub, growing 4 or 5 feet high, and, in dry soils| 

 enduring 10 or 12 years. The flowers are proJ 

 duced in large whorls, and have a very conspicuouj 

 appearance. The plant well merits 

 a place in collections, on account 

 of the remarkable appearance of 

 its foliage, independently altogether 

 of its flowers. ^ 



Rosmarinus officindlis L. (Fl 

 Greec, 1. 1. 14. ; and om fig. 1310.) 

 is a well-known evergreen shrub, 

 a native of the South of Europe, 

 which has been an inhabitant of 

 our gardens since 1348. There 

 are plants of it in diflTerent gardens in the neighbourhood 

 of London, which, as bushes in the open border, in 3 or 6 

 years have attained the height of as many feet, and breadth 

 in proportion ; thus forming very handsome evergreen 

 bushes. As the plant flowers from January to April, it 

 forms, when so treated, a very desirable garden ornament. 

 There are, also, a variety with the leaves variegated with 

 gold colour, and a silvery-leaved variety ; but these are 

 often r .ther weaker, and more dwarf, than the species. 



"Lavandula Spica L. (N. Du Ham., 3. t. 42. ; and our fig. 

 1311 .), the common Lavender, is a well-known fragrant shrub, 

 a native of the South of Europe and North of Africa, which 

 like the rosemary, has been long an inhabitant of British gar- 

 dens. In deep, dry, calcareous soils, it will grow to the height
