preserve may "be made out of the fruit. The peel has the sweetish 
flavor of the kumouat. It is known in Australia as the native 
lemon. The plant was described botanically in a footnote to Lt, 
Col. Thomas Livingston Mitchell's *Journal of an Expedition into 
the Interior of Tropical Australia in Search of a Route from 
Sydney to the Gulf of Carpentaria* . This plant was discovered on 
October' 17, 1846, not far from Lt. Col. Mitchell's camp, near the 
juncture of the Maranoa and Merevale Rivers, in the^ southern 
limit of Queensland, latitude 26° S. Decidedly cold weather was 
encountered near this point, in some cases the ice being so thick 
that it had to be broken in the morning before the horses could 
drink. It seems quite probable from this that the plant grows in 
a region where the temperature occasionally falls to 10° F. and 
in rare cases nearly to zero. It is the hardiest of all evergreen 
citrus fruits and is very promising for use in breeding new and 
hardy types. Not only has it. highly developed ability to with- 
stand cold, but it is very likely to have an even more desirable 
quality of being able to withstand occasional spells df hot 
weather in winter, a quality usually possessed by deserx, plants 
and also characteristic of the kumquat, to which this plant is to 
be referred. It is not at all impracticable that it can be util- 
ized in its present form in many parts of Arizona, as well as in 
some parts of southern Utah, Nevada and southern Oregon. It is 
obviously drought resistant, a point of the very greatest inter- 
est, both botanically and agriculturally, and its introduction 
into the United States will undoubtedly lead to the inauguration 
of a new era in the breeding of citrus fruits." (W. T. Swingle.)

western China. Presented by Mr, E. H. Wilson, botanical collector

29523, "Hoa ma. This is perhaps the most important fiber produc- 
ing plant in western China. It is cultivated extensively as a 
winter crop on the Chengtu plain, especially around the cities 
of Wen Chiang Hsien and Pi Hsien. The fiber is used for making 
coarse cloth, cordage, etc., and is also largely exported to 
other parts of China, via Chungking and Ichang," (Wilson,) No. 
29524. "Man ma. This is cultivated as an autumn crop in the 
mountains west of Ewan Hsien, between 3*000 and 5,000 feet. The 
fiber is apparently only used locally by the peasants." (Wilson.)
