1296. Sesamum. From the Arabic word semsem. Forskahl, p. 68. These plants were introduced into 
Jamaica by the Jews, and are now cultivated in most parts of the island. They are called vanglo or oil-plant 
The seeds are frequently used in broths by many of the Europeans,but the Jews make them chiefly into cakes. 
Many of the oriental nations look upon the seed as a hearty wholesome food, and express an oil from them, 
not unlike, or inferior to, the oil of almonds. It has been also manufactured for salad oil in this country, but 
without much success. 
S. orientale is frequently cultivated in the Levant, and also in Africa, as a pulse: the seeds have been 
introduced in Carolina by the African negroes. An oil is extracted from the seeds which will keep many 
years, and not acquire any rancid smell or taste, but in two years become quite mild, so that when the warm 
taste of the seed, which is in the oil when first drawn, is worn off, it is used as salad oil, and for all the pur- 
poses of sweet Oil. 
The seeds are also used by the negroes for food : they parch them over the fire, then mix them with water, 
and stew other mgredients with them. A pudding is made with them, in the same manner as with millet or 
nee. 
In Japan, China and Cochin-China, where they have no butter, they use the oil for frying fish, and in 
dressmg other dishes ; as a varnish ; and medicinally as a resolvent and emollient. Nine pounds of tlie seed 
yield upwards of two pounds of neat oil. 
1297. Pentstemon. From ■^ivn, five, and s'Yif/,ov, a stamen, because of the four perfect and one imperfect 
stamen of the genus. Beautiful herbaceous plants, deserving a place in every garden.
