A. Lebbek, Benth. (Mara, S. ; Kona, Vakai, T. ; Fl. Cey., IL, 128), in 
dry zone, rare, often planted, is said to yield an insoluble gum, used 
in India under the name “ Lera ” to adulterate gum arabic. A. procera, 
Benth., planted at Peradeniya, is said to give a gum. 
A. odoratissima , Benth. (Suriya-mara, S. ; Ponnaimurankai, T. ; FL 
Cey., II., 129), common in low-country, and in India and Malacca, yields 
a dark brown soluble gum. 
A. stipulate , Boiv. (Kabal-mara, Hulan-mara, S. ; Fl. Cey., II-, 129), 
common in moist low-country, often planted for shade, and in India 
and Malaya, yields a gum used by the Nepalese for sizing paper. 
Anacardium occidentale , L. (Kaju, S. ; Montirikai, T.; Cashew Nut ; 
Fl. Cey., I., 317), common in low-country, probably introduced by the 
Portuguese, yields Cashew gum, collected in S. America, a gum of 
inferior type, only partially soluble in water. Might prove useful 
locally as mucilage. 
Anogeissus latifolia , Wall. (Dawu, S. ; Vekkali, T. ; Fl. Cey., IL, 162), 
in the Bintenna district, rare, and S. India, yields a clear gum of 
arabin type, used for calico printing in India, especially with certain 
dyes, for which it is preferred to gum arabic. Also used as a food. 
Artocarpus incisa , L. (Rata-del, S. ; Breadfruit), and A. integrifolia , 
L. (Kos, S. ; Pila, T. ; Jak), both largely cultivated in Ceylon, are said 
to yield gums. A. Lalwocha , Roxb. (Kana-gona, S.; Fl. Cey., IV., 99), 
moist zone, rare, yields a dark gum. 
Azadirachta indica , A. Juss. (Kohomba, S. ; Vempu, T. ; Margosa or 
Nim ; Fl. Cey., I., 244), common in dry zone, and planted, and in India, 
yields a pale yellow gum. 
Bassia longifolia , L. (Mi, S. ; Illuppai, T. ; FL Cey., III., 79), common 
in dry zone and S. India, is said to yield an inferior gum, used 
medicinally. 
Bauhinia racemosa, Lam. (Mayila, S. ; Atti, T. ; Fl. Cey., II., 116), 
common in dry zone, and India to China, is said to give a gum of 
tragacanth type known as “ Semla gond ” in India (cf. Agric. Ledger, 
1900, p. 115). B. Vahlii , W. & A., introduced at Peradeniya from 
N. India, 1880, and other species of B ., probably yield similar gums. 
Bombax malabaricum , DC. (Katu-imbul, S. ; Parutti, Kaddu-parutti, 
T. ; the Cotton Tree ; Fl. Cey., I., 160), common to 2,500 feet, Indo- 
Malayan, yields a reddish-coloured bassorin gum. 
Borassus flabelliformis , L. (Tal, S. ; Panai, T. ; Palmyra Palm ; FL 
Cey., IV., 336), cultivated in dry zone, yields a dark gum from wounds. 
Butea frondosa, Roxb. (G-as-kela, S. ; Parasu, T. ; FL Cey., II., 66), 
Bibile and other places in dry zone, and in India. A dark red astrin¬ 
gent juice exudes from natural or artificial wounds, and hardens into
