Cinnamomum wightii Meisn.
Family: LAURACEAE
Vernacular names:
Kannada: Kadu dalchini
Malayalam: Kattu karuva
Sanskrit: Tejpatra
Tamil: Sempala, Vattadu, Kattu lavangam
Threat status:
Endangered (B2a, b)- Globally
Habit: Tree
Habitat: Shola forests to evergreen forests
Altitude: 900-2600m
Distribution:
National: Endemic to Western Ghats of Southern India.
Regional: A single herbarium specimen collected from Coorg district in the early 19th century (deposited in Kew Herbarium, England) was the only collection from Karnataka. Rarely seen in Eravikulam and Mannavan shola forests in Idukki district and in Silent Valley of Kerala. In Tamil Nadu, frequent in the higher altitudes of High Wavy Mountains, Kodaikanal, Nilgiri and Anamalai forests.
Description: Densely foliaceous shola trees, up to 30 m tall and about 2 m girth. Outer bark smooth, grey, thin; inner bark about 1cm thick, whitish yellow, strongly aromatic. Crown compact, nearly ball shaped. Branchlets slightly 4-angled, hairless. Leaves opposite or alternate, broadly elliptic to egg-shaped, 7-12x3-7 cm, base rounded to truncate, apex acute, leathery, smooth and shiny, bluish grey below, hairless, with 3-5 strong basal nerves, distinctly stalked. Flowers bisexual, about 5 mm long, shortly stalked, yellowish, arranged in 6-10 cm long axillary brown tomentose panicles. Berries ellipsoid, about 1.5 x 1cm, smooth, ripening brown, seated on a fleshy inverted cone-shaped about 1 cm long cup.
Trade information: Local, domestic and commercial
Special characters: This species can be identified by its compact ball-like crown, copper-coloured new foliage and brown tomentose flowering branches. Like other Cinnamon, it has fragrant bark tomentose flowering branches. Like other Cinnamon, it has fragrant bark and leaves, 3-5 strong nerves arising from the base of the leaves and the fruits seated on an enlarged fleshy cup.
Mode of propagation: By seeds and stem cuttings.
Medicinal Uses: Bark, leaves and oil used to treat paralytic disorders, deficiency in digestive power, abdominal disorders, cough, dysuria and gynaecological disorders. Tender fruits, including stalk and calyx, are astringent, aromatic, stimulant and carminative.
Phenology:
Flowering: April to June
Fruiting: From May onwards
Notes: If destructive collection of bark and leaves (adulterated with commercial Cinnamon), is not controlled there may be a serious threat to the existence of this endemic species in a short span of time. Dr. P.V Sharma, in his Dravyaguna Vigyana, says that, apart from bark and leaves, the flower buds are used as medicine, which are known as ‘Kala nagkesar’ (Nattu nagkesar). Nagkesar refers the flower buds of Mesua ferrea.

Notes: Endemic plants of the Indian region (Vol. 1. p 93. 1987) by M. Ahmedullah & M.P. Nayar records its presence in Deccan and Eastern Ghats also which seems to be an error on account of mistaking Hardwickia binate as H. pinnata. The latter is a synonym of Kingiodendron pinnatum. Hardwickia binate is a different species occurring in drier zones.

Notes: This species is closely allied to the more commonly availbale Heliotropium indicum. Therefore, Heliotropiumkeralense could be a potential substitute/adulterant to Heliotropium indicum. Moreover, being an endemic species so far recorded only from Kerala, it deserves prime conservation concern.
