From Amboyna this magnificent tree was introduced into 

 the Botanic garden at Calcutta, in 1797. [n 1810, they began 

 to blossom in June, the trees were then fifty feet high, and 

 the trunk of the largest rather above three feet in circumfer- 

 ence, four feet above ground, while young their growth was 

 not rapid. 



Trunk perfectly straight, like the pines, to the very top of the 

 tree. Bar k smooth, dark brown. Branches decussate. Branch- 

 lets round and smooth. Leaves opposite, stem-clasping, broad-

 the branchlets, yet taper more toward the much waved base 

 than the apex, somewhat villous particularly underneath, veins 

 parallel ; length from eight to twenty-four inches, and broad in 

 proportion, when the trees were young, they were even more 

 than two feet long. Stipules opposite, linear-lanceolate, con- 

 cave, smooth and veinless, about three inches long. Pedun- 

 cles terminal, solitary, length of the stipules, recurvate, giv- 

 in°- support to a single most beautiful flower, of full three 

 inches in diameter, and sweet smelling, the corollets are very

 funnel-shaped. Tube slender, widening gently to the mouth; 

 segments five, ovate-oblong, spreading. Filaments none. An- 

 thers attached to the mouth of the tube of the corol, under the 

 fissures of its border, sagittate. Germ numerous, distinct, in-

 imbricated ovula in each, attached to every part of a free li-
