Guizotia oleifera, Candolle. 
India and probably also Abyssinia. The Hamtii oil is 
pressed from, the seeds of this annual herb, which 
yields its crop in three months. The oil is much used 
like Sesamuui oil, as well for culinary as technic pur- 
poses. 
Hedeoma pulegioides, Persoon. 
The Pennyroyal of North America. An annual herb of 
aromatic taste, employed in medicine. 
Hedysamm coronarium, L-* 
The Soola Clover. South Europe. One of the best of 
perennial fodder-herbs. It carries with it also the recom- 
mendation of being extremely handsome. 
Helianthus annuus, E.* 
The Sunflower. Peru. This tall showy and large-flowered 
annual is not without industrial importance. As much as 
50 bushels of seeds or rather seed-like nutlets have been 
obtained from an acre under very favorable circumstances, 
and as much as 50 gallons of oil can be pressed from such a 
crop. The latter can be used not only for machinery, but 
even as one of the best for the table. Otherwise the seeds 
afford an excellent fodder for fowl. The stalks furnish a 
good textile fibre and the blossoms yield a brilliant lasting 
yellow dye. About G lbs. of seeds are required for an acre. 
The plant likes calcareous soil. Several allied North 
American species deserve perhaps rural culture. The 
return from a Sunflower field is attained within a few 
months. 
Helianthus tuherosus, L. 
Brazil. Sunflower Artichoke. Inappropriately passing 
under the name Jerusalem Artichoke. The tubers are 
saccharine and serve culinary purposes. The stem is rich 
in textile fibre. The percentage of crystalline sugar is 
largest during the cold season, namely 5-6/100. During 
the summer the starch-like Inulin prevails. This plant 
can only be brought to full peffectiou in a soil rich in 
potash.
