50(5 LXXXII. VERBEKACE^ [Tectona 



erect, 1-3 ft. long. Er. a hard bony nut, enclosed in a thick spongy coverino- 

 consisting of a dense felt of branched hairs, seeds 1-3, rarely 4, a central 

 cavity having the appearance of a 5th cell. When the seed germinates, the 

 outer wall of each cell comes off bodily like a round concave cap. The inflated 

 calyx, which encloses the fr. like a bladder, is generally ovoid, 1-1^ in. diam., 

 reticulate and more or less corrugated. 



The Teak tree is indigenous in both Peninsulas of India, in the nortli-eastern drier part 

 of Java and in other islands of the Indian Archipelago. In Western India it attains its 

 northern limit in the Western Aravallis at 24° 42^ N. Lat. (A. E. Lowrie). In Central 

 India its northernmost point is the Jhansi district at 25^33' and from that point the line 

 of northern limit continues in a south-easterly direction to the Mahanadi river in the 

 Central Provinces. In Upper Burma it extends to lat. 25° 30', and ascends to 3,000 ft. 

 Teak, however, is not uniformly distributed over this large area, for there are many 

 districts where it is entirely absent. It is cultivated in Bengal and Assam, and in 

 Northern India as far as Dehra Dun. 



Teak grows on a great variety of soils, but requires perfect drainage. It thrives 

 equally -well on the sandstone of the Pegu Yoma, on the granite of the eastern Sitang 

 and the North Kanara Porests, on limestone in the Thaungyeen forests of Tenasserim, 

 and on basaltic rocks in tlie lOiandeish Daugs, and the Satpura range. On alluvial 

 soil the stems generally are fluted and irregularly shaped. 



It is not gregarious, though on deep alluvial soil small patches of nearly pnre Teak 

 forest are occasionally found (Beeling, Domdamee in Martaban. Banks of the Godavari 

 [Gamble]). A large area of pure Teak is in the Katu forest (Katha district) of Upper 

 Burma. Woods in which Teak, mostly stunted, preponderates, also occur here and 

 there on dry rocky ground. Its associates are, besides Bamboos, the trees of the deciduous 

 forest. 



In dry and hot situations Teak loses its leaves in November, December or early in 

 January, Where the ground is moist, the tree often remains green until March. 

 The new foliage comes out in May. It flowers during the rains in July and August, 

 and ripens its seed between November and January. In summer it is readily recog- 

 nized at a considerable distance by the flower panicles, which overtop the green 

 foliage, and in winter the feathery erect fruit panicles distinguish it from all other 

 trees. 



On good soil and in a suitable climate Teak has an exceedingly rapid growth while 

 young. It co|)pices well. It demands much light and in this respect its requirements 

 are similar to those of QHercm sessiliflora and Finns s^ijive.sfris in Europe. Its strong 

 point is the vigorous terminal shoot, which enables it, like Fraxinus exceh ior, to pierce 

 through dense brushwood, provided there is sufficient light overhead, to stimulate its 

 growth. The white mineral dejDOsit found in cavities in the w^ood, as far as known, 

 mainly consists of Calcium Phosphates.
