319. Sands, W. N. Bougainvillaeas. Imp. Dei)t. Agric. West Indies Rept. Agric. Dept. 

 St. Vincent 1918-19: 1-2. 1920. — The following varieties of Bougainvillaea are under cultiva- 

 tion: B. glabra (light magenta), B. Sanderiana (magenta), B. spectabilis var. laterita (terra- 

 cotta), and B. var. "Mrs. Butt" (crimson). Artificial crosses of these lead to the opinion 

 "that the magenta color in the bracts is dominant over crimson and terra-cotta reds as all 

 hybrids raised in the W. I., so far as known, in which a magenta-bracted species or variety 

 was one of the parents, have produced magenta-coloured bracts." The period between 

 pollination of flowers and ripening of seed is about 30 days, and the seed, which resemble 

 grains of wheat, germinate in about 10 days in partially sterilized soil. Seedlings are rather 

 difficult to raise. — J. S. Dash.

 23:272-273. 1921. — The wine has a sp. gr. of 1.0295 and contains 2 per cent of glycerin, 3 of 

 gum, 7 of mineral matter, and, after allowing it to stand for about 1 week, 4.5 per cent of 

 alcohol by weight. The wine is obtained by puncturing the palms of the oasis Gfabes. It 

 flows at the rate of 7-8 1. per day for 1 month. The puncture is closed with vegetable mat- 

 ter or dirt and the tree regains its normal appearance after 1 year. The wine is consumed by 

 the natives very frequently immediately after collecting, even before fermentation has 

 started. — H. Engelhardt.
