﻿OCTOBER 1 TO DECEMBER 31, 1918. 37 



46802 and 46803— Continued. 



46803. Peesea Americana Mill. Lauracese. Avocado. 

 (P. gratissima Gaertn. f.) 



"No. 23556. Quito, altitude 9,500 feet. October 28, 1918." (Rose.) 

 " This variety apparently belongs to the Mexican race. It will prob- 

 ably be hardy and should be tested in sections of the United States 

 which are slightly too cold for avocados of the West Indian or Guate- 

 malan races. It is probable that it will prove to be a small-fruited variety 

 of rich flavor, as the Mexican race usually produces fruits of this char- 

 acter." (Wilson Popenoe.) 



46804 to 46820. 



From Johannesburg, South Africa. Presented by Mr. J. Burtt Davy. Re- 

 ceived December 9 and 10, 1918. Quoted notes by Mr. Davy. 



46804. Acacia cyclops A. Cunn. Mimosacese. 



" Naturalized on the Cape Flats, where it has proved valuable as a 

 sand binder. Should succeed equally well on the California coast." 

 For previous introduction, see S. P. I. No. 30777. 



46805. Acacia giraffae Willd. Mimosacese. 



" Eameel doom. A valuable timber tree for arid regions in the warm 

 Temperate Zone. One of the few native trees in British Bechuanaland. 

 The ripe pods are greedily eaten by stock. It thrives in sandy soil, 

 attains a large size, and furnishes valuable shade. The wood is dark 

 red-brown in color and is used by the Bechuanas for spoons, knife han- 

 dles, etc. At one time this tree furnished all the fuel for Kimberly, 

 Vryburg, and Maf eking." 



46806. Eragrostis superba Peyr. Poacere. 



'A valuable pasture grass; somewhat ornamental also." 

 For previous introduction, see S. P. I. No. 44741. 



46807. Hibiscus urens L. f. Malvaceae. 



" Wilde Stok-roos. Ornamental perennial from the Calvinia Division, 

 Cape Province, with a rainfall of under 4 inches." 



A strong-growing, shaggy plant with handsome, deep-crimson flowers 

 which are produced throughout the whole summer. (Adapted from 

 Harvey and Sonder, Flora Capensis, vol. 1, p. 173.) 



46808. Lobelia erinus microdon (DC.) Sond. Lobellacese. 



'An ornamental annual, entirely different in habit from the ordinary 

 garden form, being erect instead of diffuse. The fragrant flowers present 

 beautiful shades of blue and white." 



46809. Manihot glaziovii Muell. Arg. Euphorbia cere. Ceara rubber. 

 " From Knysna, Cape Province." 



" Ceara rubber occupies the second rank, and it would undoubtedly be 

 equal to Para rubber if the sap were collected by some method so that 

 it would not include so much foreign stuff. Ceara rubber is very elastic, 

 dry, and not sticky unless it is impure, but when impure the loss in bulk 

 amounts often to 25 per cent. The tree grows to a height of about 30 

 feet with a round head. It has 3 to 7 lobed gray-green leaves, in shape 

 and size resembling those of the castor-bean plant." (Semmler.)
