ROYDSIA (named by Dr. Roxburgh in hononr of Sir 
John Royds, “one of the Puisne Judges of the Supreme 
Court of Judicature of Bengal, and an eminent benefactor 
to the Science”). Onn. Capparidee. A small genus (two 
species) of stove shrubs, natives of the East Indies and 
the Philippine Islands. Flowers yellow, small, fragrant 
axillary and in terminal panicles; sepals six, coloured, 
imbricated or sub-valvate; petals none; torus short; 
stamens very numerous; pedicels bibracteate at base. 
Fruit red, olive-shaped. Leaves ample, shortly petiolate, 
simple, oblong, exstipulate. R. suaveolens, the only species 
introduced, is a rather coarse, rambling bush, well worth 
cultivating for its delicious fragrance by those who can 
give it space enough: it is not suited for small houses. 
The plant thrives in good, rich, loamy soil, and may be 
readily increased by cuttings of the young wood. 
R. suaveolens (sweet-scented). (fl. numerous, jin. in diameter, 
fragrant; stamens about 100, spreading; racemes axillary, or 
rather above the axils, din. to 7in. long, solitary or in terminal

4in. to 12in. long, oblong or oblong-lanceolate, rarely oblanceolate, 
acute or acuminate, entire, shining, pale beneath ; petioles jin. 
to Sin. long. East Indies. (B. M. 6881.)

mid-lacinia; raceme few-flowered. J. broadly ligulate, blunt,

stripes, the sepals oblong-ligulate, the petals nearly so; lip white,
