Notes on some Asiatic species of Aquilaria (Thymelaeaceae)

The name Aquilaria agallocha was published by Roxburgh (1814) in his Hortus Ben-galensis. A short diagnosis of this species ('Leaves lanceolar. Umbel lateral, subsessile'), followed by a note, was published in the Carey edition ofRoxburgh's Flora Indica (1832).

Linn. Soc. London, vol. 21 (pp. 199—206, t. 21). The descrip-tion was chiefly based on one of the trees sent by R. K. Dick from Silhet to the Botanic Garden at Calcutta. This tree blossomed there in 1809 and 1810. Roxburgh was aware of the similarity between his A. agallocha and Lamarck's A. malaccensis as he stated that 'Lamarck's description of the specimen [ofA. malaccensis] presented to him by Sonnerat agrees almost exacdy with our plant. The inflorescence is only required to confirm their being the same species, or different ' (cf. also Roxburgh 1832). In a footnote on p. 202 of the same paper, possibly added by Colebrooke, was stated: 'Since writing the above Dr. Roxburgh has received living plants, and perfect capsules with their seeds, of th
