Very near to E. Kunthianum, but with more obovate and more obtuse leaves ; it is 

 further described as a tall tree, whilst the Khasia plant is a mere bush. The Penang 

 and some Malaccan specimens have much smaller leaves than the Mergui ones. I have 

 seen no Sumatran specimens. 



** Leaves not glaucous beneath, but more or less shining on both sur- 

 faces.

WESTERN PENINSULA; Courtallum, Wight; CEYLON, banks of streams, Galagama dis- 

 trict, alt. 2-3000 ft., Thwaites, &c. 



An erect branching shrub. Leaves sometimes slightly contracted towards the base, 

 nerves not connate into a distinct intramarginal one ; petiole y^-g in. Wight's var. 

 obtusifolivm and his S. erythoxyloides are hardly distinguishable ; the latter is a 

 short-styled form, with alternately longer stamens ; another form with longer styles and 

 shorter stamens occurs ; as is the case with the two following species ; all are no doubt 

 dimorphous.

This differs from E. lanceolatum in the long points to the comparatively 

 broader leaves, which have furthermore horizontal nerves ; and in the short stout 

 peduncles. Thwaites notices two forms of flower, one (stylosa] with the alternate 

 stamens longer, and a shorter style; the other (staminea) with equal stamens and a 

 longer style. The expressed juice of the fresh leaves is given by the Cinghalese as an 

 anthelmintic to children. There is a very similar species to this, a variety of it, in 

 Borneo. 



6. E. obtusifolium, Thwaites Enum. 54 ; leaves 2-3^ by 1^-lf in. 

 obovate-obtuse or broadly oblong tip rounded or obtusely pointed rather 

 shining on both surfaces nerves rather oblique elevated, pedicels short 

 stout. 



CEYLON; Central Provinces, alt. 2-4000 ft., Thwaites. 



I follow Thwaites in retaining this as a distinct species, though I can scarcely doubt 

 its being a broad-leaved state of E. lanceolatum, its nerves are less oblique however. 

 It occurs under the two forms of long stamens and short style and vice versa. Fruit 

 in Thwaites's drawing ^ in. long, linear-oblong, straight, red. Thwaites refers to this 

 the S. lanceolata, var. obtusifolia of Wight, which is, however, clearly a very trifling 

 variety of S. lanceolatum. 



DOUBTFUL SPECIES. 



E. SIDEROXYLOIDES, Lamk. Tbis is a Mauritian species, mentioned by Roxburgh (ii. 

 449) as having been sent from Ceylon to the Botanic Garden of Calcutta by General 

 Macdowall, and as being also a native of Coromandel. As no description is given I 

 cannot say to which of the above Roxburgh's Coromandel species it should be referred.
