PLANT MATERIAL INTRODUCED 



Tropical plants of particular value for southeastern Florida were sent in from 

 the Allison V. Armour expedition and are recorded under Nos. 75270 to 75285. 



An interesting collection of native tj-pes and varieties of peaches and apricots 

 (75228 to 75238) were sent in from Persia, and a smaller group of mangos (75264 

 to 75269) from Honolulu may add valuable new fruits for several localized areas 

 in our country. 



Interest in rubber-producing plants is noted — three importations of Crypto- 

 stegia (75218, 75219, 75752), latex-producing shrubby vines which seem to 

 promise well in southern Florida. 



The increasing interest in bamboos is reflected in the collection (Nos. 75146 

 to 75170) sent in by Dr. A. W. Hill, Director of the Royal Botanic Gardens, 

 Kew, England, for study in regard to hardiness and suitability for use in orna- 

 mental and commercial plantings in the warmer parts of the country. 



Of more isolated interest, one finds a gladiolus (No. 75657) sent in from South 

 America, where it was collected apparently in the wild, a new location for this 

 genus. 



Large collections from the Melbourne Botanic Garden, Victoria (Nos. 75534 

 to 75574), and the Sydney Botanic Gardens, New South Wales (Nos. 75576 

 to 75612), are rich in both Acacia and Eucalyptus, genera of great value and 

 importance in California and the Southwest. Many of these are species or 

 horticultural forms not previously introduced into this country. 



Even from so brief an outline as this, it is possible to see how diverse are the 

 materials that are brought in by this office. It is impossible to suggest at this 

 time the specific reasons for which they were secured or to indicate the disposition 

 that has been made in each case, but the reader is urged once more to recall that 

 the activities recorded here are all related to problems under consideration by the 

 department and do not represent a check list of materials for distribution. 



The botanical determinations of these introductions have been made and the 

 nomenclature determined by H. C. Skeels, who has had general supervision of 

 this inventory.

1 It should be understood that the names of horticultural varieties of fruits, vegetables, cereals, and other 

 plants used in this inventory are those under which the material was received when introduced by the 

 Office of Foreign Plant Introduction, and, further, that the printing of such names here does not constitute 

 their official publication and adoption in this country. As the different varieties are studied, their entrance 

 into the American trade forecast, and the use of varietal names for them in American literature becomes 

 necessary, the foreign varietal designations appearing in this inventory will be subject to change with a 

 view to bringing the forms of the names into harmony with recognized horticultural nomenclature. 



It is a well-known fact that botanical descriptions, both technical and economic, seldom mention the 

 seeds at all and rarely describe them in such a way as to make possible identification from the seeds alone. 

 Many of the unusual plants listed in these inventories are appearing in this country for the first time, and 

 there are no seed samples or herbarium specimens with ripe seeds with which the new arrivals may be 

 compared. The only identification possible is to see that the sample received resembles seeds of other 

 species of the same genus or of related genera. The responsibility for the identifications therefore must 

 necessarily often rest with the person sending the material. If there is any question regarding the correct- 

 ness of the identification of any plant received from this office, herbarium specimens of leaves and flowers 

 should be sent in so that definite identification can be made.
