slightly rounded at base, serrulate, l£-2 in. long, f-1 in. broad ; petiole 

 l-i-2 iines. Flowers yellowish, in axillary, shortly pedunculate, few-flowered 

 cymes of £ in. or less ; pedicels equalling or shorter than the flower. Sepals 

 rotundate. Petals spreading, broadly elliptical or obovate, very obtuse. 

 Stamens inserted within a rather loose cup-shaped disk. Filaments linear, 

 recurved. Fruit not seen.

lfi. H. longipetiolata, Oliv. Wholly glabrous. Leaves rather covia- 

 ceous, lanceolate or elliptic-lanceolate, usually obtusely pointed or shortly 

 acuminate, narrowed below into the long petiole, serrulate or sen-ate, nearly 

 entire towards the base, with 3-5 principal lateral veins directed forward 

 on each side the midrib ; lamina 1-3 in. long, i~l£ in. broad ; petiole J-f 

 in. ; the lowest pair of the lateral shoots occasionally linear, i in. broad. 

 Flowers in axillary divaricately dichotomous cymes shorter than the leaves ; 

 bracts minute, ovate, acute. Petals broadly- or obovate-elliptical, broadly 

 imbricate. Filaments short, much dilated below almost from the recurved 

 anther, extending but little above the glabrous ovary around which they are 

 closely connivent. Fruit-carpels coriaceous, obovate to obovate-lanceolate, 

 obtuse, 2-2| in. long, f-l| in. broad.

Flowers hermaphrodite. Sepals 5. Petals 5. Stamens 3. Anthers 

 variously 2-celled or -lobed ; cells distinct or confluent, or 1-celled (4-locd- 

 late). Filaments usually inserted within or upon a disk. Ovary 3-celleo; 

 style very short or subulate ; stigma terminal ; ovules 2 or more in each cell. 

 Fruit baccate, undivided, 1-3-celled, 1- or several-seeded.— Shrubs or small 

 trees, sometimes scandent, glabrous. Leaves opposite or subopposite, coria- 

 ceous, subentire or serrulate. Flowers small, usually in axillary sessile or 

 very shortly pedunculate fascicles. 



Another large tropical genus, common to both hemispheres. I have not identified any o 

 the African species with either Indian or American forms, unless it be S. prinoides. 1 

 species are difficult to discriminate, and the following key is but a very imperfect aid tot&e 

 identification. Several are known from very imperfect material.
