262 Hsematoxylon campechianum, Liira. 



The American logwood tree. This has been 

 cultivated in the Botanical Gardens for many years, 

 where, however, it only attains to the size of a 

 scandent bush or small tree. The red-coloured . 

 heartwood affords a well known dye, or rather a 

 series of dyes of the darker tints such as grey, 

 violet, blue, and even black. Logwood does not 

 coppice, but it bears a lot of pruning, makes a 

 durable fence and grows fairly well from seed. The 

 species will become naturaHsed in this country 

 eventually. It should be included in garden shrub- 

 beries, as the racemed, yellow flowers are both 

 showy and sweetly scented, 



263 Colvillea racemosa, Boj. This grand tree was 

 introduced by the writer in 1880 and there are now 

 several good specimens in local cultivation. The 

 best one is on the lower terrace in front of the exhibi- 

 tion building in the Botanical Grardens, where it 

 flowers profusely in the month of September. The 

 foliage resembles that of the 'gold mohur' tree, for 

 which the species might readily be mistaken when 

 undersized and not in blossom. But the Colvillea 

 racemosa is a lofty evergreen tree which flowers at 

 the close of the south-west monsoon. The inflore- 

 scence consists of a terminal, drooping panicle, or 

 compound raceme of rich golden flowers supported 

 on reddish calyces. As an ornamental tree of moder- 

 ately rapid growth, this species has few equals ; and 

 when seedfings become plentiful it wiU spread 

 quickly and become a prominent feature in local 

 vegetation. Avenues of the tree would have a 

 splendid effect. Propagate from seed, and plant 

 in loose soil at 35 feet apart. 



264 Ceratonia siiiqua, Linn. 



The carob-bean tree. Also known by the popular, 

 names of " St. John's bread, " "Locust tree" and 

 J'Algaroba," A small evergreen tree of Spain^
