70 SEEDS AND PLANTS IMPORTED, 
33071. Ficus macrophylla Desf. Moreton Bay fig. 
From Sydney, New South Wales, Australia. Presented by Prof. J. H. Maiden, 
Director and Government Botanist, Royal Botanic Garden. Received March 
7, 1912. 
"This only grows in the well- watered coastal district, and experiments with the 
view to introduce it into drier localities have almost invariably resulted in failure." 
{Maiden.) 
See No. 3494 for previous introduction. 
Distribution. — A large tree found near streams in Queensland and New South Wales 
in Australia. 
33073. Hedysarum coronarium L. Sulla. 
From Jerez de la Frontera, Spain. Presented by Mr. Percival Gassett, American 
consul. Received March 7 and 19, 1912. 
"The sulla plant, or Spanish wild clover, is found in Spain only in southern Anda- 
lusia, province of Cadiz, where it grows wild and with most luxuriance in abandoned 
vineyards. The Spaniards are well aware of the great value of this plant as a rich 
forage for stock, especially for horses, to whom it is said to give endurance; and not 
enough sulla can be produced in Jerez to supply the demand, for, after the stock raisers 
and farmers who grow it have supplied themselves, any surplus is eagerly purchased 
by the military officers in charge of the Jerez Deposito Semental or depot for breeding 
horses for the Spanish army. So far, all efforts to make it grow in other parts of Spain, 
even at Seville, 90 miles from Jerez, have been unsuccessful. 
"'Practically, then, sulla needs the same climate and soil that produce the famous 
Jerez, or sherry, grape, unique of its kind in the world. The climate should be sunny, 
hot, and dry in the summer, with plenty of rain in the fall, and a low temperature 
that does not reach freezing, although occasional frosts during the winter nights are 
not unknown in Jerez. When there has been plenty of rain in the fall there has 
usually been an abundant crop of sulla the next spring. 
"Now as to soil. Jerez has three soils, each of which produces a distinct type of 
wine; the best is known as 'albariza' (lime), the second best as 'barro' (clay), and the 
least desirable as 'arena ' (sand) . As a general rule the soil of Jerez vineyards is of a 
porous character, light, and of a grayish color, the composition of which, according to 
an analysis made in 1898 in the laboratory of the London Lancet is as follows: 
Per cent. 
Calcium carbonate 29. 12 
Oxide of iron 4. 08 
Sand, etc 45. 80 
Soluble salts .50 
Moisture 16. 70 
Loss on ignition , . 3. 80 
100. 00 
"Practically a third part of this soil consists of carbonate of lime and if the fact of 
producing the nearest imitation of Jerez wine is any indication, it would seem as if sulla 
might grow in parts of California. 
"Although the general belief, which seems to be supported by all other unsuccessful 
experiments, is that this soil is indispensable for the successful growth of sulla, yet 
the writer has within a month or so seen an entire field of sulla, a foot or more in height, 
growing in ordinary black soil, without irrigation, at the Jerez Agricultural Experi- 
ment Station, La Granja.
