ARBORETUM AND FRUTICETUM, 



Celsia laniita Jac., Bot. Reg., t. 438., and our fig. 

 11 ai., is a suffruticose plant of uncertain origin, but 

 with showy yellow flowers, which it produces from 

 July to September. It is commonly kept in a frame, 

 but would thrive well on conservative rockwork, in a 

 favourable situation. 



Capraria lanceolata L. ; Frcelfnia salicifdlia Bot. 

 Mug., t. 155R. ; is a native of the Cape of Good Hope, 

 introduced in 1774. A plant has stood against the wall 

 in the Chelsea Botanic Garden for several years; 

 and, though it is generally klled down to the ground 

 in winter, it has always hitherto sprung up again in 

 spring, and made a much finer appearance than it 

 could possibly have done in a pot. 



The genera Aionsda, R. ct P., Angelbnia H. B. et 

 Kunth, I jOplwsptrmum Don, Rhodochlton Zucc., Nyc- 



tcrinia D. Don" all contain species which might be tried 

 wall in the south of England.

If, after perusing what is stated in this work respecting the half-hardy ligneous 

 plants of any order or tribe, the reader will turn to the same natural order or tribe 

 in our Hort. Brit., he will generally find a number of other species, green-house or stove plants, and 

 tuffruticose or completely ligneous, from which he may increase his selection fortrial in the open air. 



CHAP. LXXXVI. 



OF THE HARDY LIGNEOUS PLANTS OF THE ORDER LABIA'CEJE. 



ALMOST the whole of the plants of this order, which are technically ligneous 

 or suffniticose, may be more properly treated, in gardens, as herbaceous plants 



than as shrubs; nevertheless, as 

 this work would be incomplete 

 without noticing them, we shall 

 name some of the principal species, 

 and refer for the remainder to 

 our Hortus Britannicus. The best 

 situation for a collection of lig- 

 neous Labiaceae, is on dry rock-

Saturcja montana L., Fl. Graec. t. 543., and ourfg. 1131., is a well-known 

 culinary herb, a native of the south of Europe, which, on dry calcareous soil, 

 will form a neat little evergreen bush, 

 from 1ft. to 2ft. in height. S. 

 capitate Willd., a native of the Le- 

 vant, is equally hardy, and, indeed, 

 appears to be only a variety of the 

 former. There are, also, some species 

 or varieties from Sicily, Candia, and 

 the Ionian Islands, which are con- 

 sidered as frame plants, and may 

 be tried on conservative rockwork. 



Thymus vulgdris L., and our 

 Jig. 1132., forms a neat little ever- 

 green shrub, when kept in dry cal- 

 careous soil, or on rockwork : and 

 T. grandiflorus Hort. ; T. Masti- 

 china L., Black., t. 134.; is a native 

 of Spain, with hoary, hairy calyxes. 

 In an arboretum where every single 

 species or variety is to be exhibited 

 by itself, such a beautiful and fragrant genus as Thy m us 

 may have a small cone or hemisphere of rockwork devoted to each species 

 or variety. There are some half-hardy species, which might also be tried. 

 They are not only beautiful when in flower, but are highly fragrant, and 

 attractive to bees. 



Hyssopus officinalis L., and our Jig. 1 1 33., forms an undershrub of 2ft. in
