NOVEMBER 1 TO DECEMBER 31, 1919. 5 



Two varieties of Natal grass {Tricholaena rosea^ Nos. 48843 and 

 48844) from New Zealand will attract the attention of horticulturists 

 in Florida, where this grass has been such a success. 



The Siberian brier {Rosa laxa. No. 48845) which, according to 

 Mr. George M. Taylor, of the Florists' Exchange, is an excellent 

 stock for roses on medium and light soils, merits trial by others. 



The growing interest in Job's-tears {Coix lacryma-jolji) as a 

 cereal and forage crop makes the collection of 16 varieties of this 

 cereal (Nos. 48860 to 48875) which Mr. Thompstone has sent m 

 from Northern Circle, Burma, of unusual importance; and, accord- 

 ing to Mr. G. N. Collins, the remarkable collection of varieties of 

 corn (Nos. 48876 to 48921) from the same region, is composed of an 

 entirely new type having waxy endosperms similar to that of a 

 single isolated sort obtained by us from China a number of years 

 ago. For breeding purj)oses these have very unusual interest. 



Through the courtesy of the Director General of Agriculture ot 

 the Belgian Kongo, M. Leplae, 51 varieties of cassava {Manihot 

 esculenta,^ Nos. 48924 to 48974) have been received for use in the 

 tests of this plant as a vegetable for home use in southern Florida. 



Pej)permint growers in Michigan will be pleased to have from 

 the agronomist of the Hokkaido Agricultural Experiment Station 

 authentic material of the best variety of Japanese peppermint 

 {Mentha piperita, No. 48980). 



Petreavoluhilis is one of the loveliest of all climbers recently intro- 

 duced into southern Florida, and another species of the same genus 

 {P. arborea, No. 49031) from Colombia, which is a shrub, will 

 meet with a warm welcome there if it approaches the vine in beauty. 



Nos. 49032 to 49050 represent seeds which were collected by Mr. 

 Allanson from the exotic fruiting trees and shrubs in the parks 

 of Rochester, N. Y., and presented to us through the courtesy of 

 Mr. Dunbar, director of the parks; and Nos. 49051 to 49123 repre- 

 sent a similar collection from the Arnold Arboretum, through the 

 courtesy of Prof. Sargent, its director. Most of them represent 

 valuable introductions made by the Arboretum. 



The botanical determinations of seeds introduced have been made 

 and the nomenclature determined by Mr. H. C. Skeels; and the 

 descriptive and botanical notes have been arranged by Mr. G. P. 

 Van Eseltine, who has had general supervision of this inventory, 

 as of all other publications of this office. The manuscript has been 

 prepared by Miss Esther A. Celander and Miss Patty T. Newbold.
