JAB 



A genus of Indian and tropical African 

 shrubs, with corymbs of handsome flowers of 

 a scarlet, pinli, or white color, and frequently 

 having an agreeable fragrance. The histoiy 

 of Ixora coccinea, the best known species, is 

 rather curious. It is a native of China and 

 some of tiie East India Islands, where it is 

 worshipped as a sacred plant, and where it is 

 said to form a small tree about six feet high, 

 rising with a single stem, and having its head 

 formed entirely of clusters of bright scarlet 

 and yellow flowers, whence it has received 

 the name of Flamma Sylvarum, or the Tree of 

 Fire. This plant was first introduced in 1690; 

 but it was i-oou lost and its existence was 

 even doubted until it was re-introduced about 

 a hundred years afterward by the celebrated 

 Dr. Fothergill. The Ixoras are really mag- 

 nificent plants, and should be grown in a 

 warm temperature. They are propagated 

 from cuttings, and should be grown in a sandj' 

 loam and leaf mould. When repotted, which 

 should be done immediately after fiowering, 

 the plants will be benefited by being plunged 

 into a moderate bottom heat, which induces

them to root freely, and to form the growth 

 quickly and with vigor, thus enabling them 

 to become properly ripened before winter. In 

 the spring, when the flower heads begin to 

 appear, a liberal regimen should be adopted, 

 and liquid manure occasionally applied. At 

 this time, and, indeed, throughout the sum- 

 mer, the foliage should be frequently syr- 

 inged, in order to keep it clear of insects, and 

 to preserve its rich green and glossiness. As 

 soon as the flowers are expanded, and onward 

 till the growth is complete, the plants should 

 be shaded from powerful light, and through 

 the summer a moderately moist atmosphere 

 of about 75° should be kept about them. In 

 winter the ordinary attention required by hot- 

 house plants will suffice. The taste for hard- 

 wooded plants is on the increase. Among the 

 best is the Ixora, which should be more gen- 

 erally grown ; over twenty species varying in 

 color, from pure white to deep orange-scarlet, 

 are now in cultivation. I. coccinea superba, 

 I. eminens, I. illustris, I. decora, I. omaia, I. 

 Williamsii and others, are free flowering and 

 easily grown species.

Jacqui'nia. Named in honor of N. J. de Jacquin, 

 once Professor of Botany at Leyden. A genus 

 of handsome evergreen bushes of the Nat. 

 Ord. ConvolvulaceoB, peculiar to America, where 

 they range from Florida to Brazil, and are 

 usually found near the coast. J. armillaris is 

 known by the West Indian settlers as Brace- 



let Wood ; the shiny brown and yellow seeds 

 being made into bracelets. Introduced to 

 cultivation in 1768.

 first discovered the plant. Nat. Ord. Saxi- 

 fragacea. 



J. Americana, the only species, is a medium- 

 sized hardy shrub, with opposite serrated 

 leaves and white flowers, like a Deutzia, 

 blooming nearly all summer. It is a native of 

 Mexico and the Rocky Mountains, and is in- 

 creased by seeds or cuttings of the ripened 

 wood. Introduced in 1865.
