species are grown under the name of jahoticaha; they art- ;<till soinewliat 

 confused botanically, but it appears that most of the plants coumion in 

 cultivation belong either to Myrciaria- cauliflora or .1/. jahoticaha, fruits 

 of the latter being distinguishable from those of the former by the pres- 

 ence of a slender stem. 



" The jahoticaha occurs in southern Brazil, both wild and cultivated. It 

 is a very handsome tree, reaching a height of 35 or 40 feet, with a dense 

 dome-shaped crown. The leaves are small, lanceolate, and light green in 

 color; flowers white, with four petals and a conspicuous tuft of stamens. 

 The fruits are produced in the greatest abundance and are the size of 

 large grapes, with a tough leathery skin, juicy white pulp of rather acid 

 aromatic flavor, and two to four flattened oval seeds. The resemblance 

 between the jahoticaha and some of the grapes of the Muscadine group, 

 e. g., James, is very striking, not only in general appearance but also 

 in flavor. 



"The jahoticaha prefers a soil that is rich and deep; it is rather slow 

 of growth, coming into bearing after six or eight years. It withstands 

 slight frosts and gives promise of being successful in southern Florida 

 and perhaps also in sheltered locations throughout southern California. 

 At the present time seed propagation is the only means of multiplication 

 which is commonly employed, but inarching or some other means of 

 propagation should be utilized to perpetuate good varieties." {Wilsoiu 

 Popenoe.)

Capoeira hranca. An interesting plant which grows on the rolling 

 prairies of the State of Minas Geraes, Brazil, and which is said to have 

 unusual value for feeding live stock, especially horses. 



Analyses made by the Bureau of Chemistry, United States Department 

 of Agriculture, show that this plant contains an unusual quantity of 

 protein. The percentages shown by these analyses are as follows : Mois- 

 ture — cleaves, 8.36 ; branches, 7.04. Ether extract — leaves, 2.29 ; branches, 

 0.59. Protein— leaves, 20.88 ; branches, 14.06. Crude fiber— leaves, 28.03 ; 

 branches, 37.45.

"A small leguminous tree which occurs commonly on the plains of 

 the State of Minas Geraes and is said by Pio Correa to be distributed 

 from Para in northern Brazil to Sao Paulo in the southern part of the 

 country. The bark contains a high percentage of tannin and is known as 

 casca da rirgindade; the seeds are said to be poisonous and the leaves to 

 have medicinal qualities. It is the bark, however, that seems^ to have 

 economic interest, being considered of value for use in tanning. Accord- 

 ing to Brazilian authorities it contains as high as 40 per cent of tannin ; 

 an analysis made by the Bureau of Chemistry, United States Department 

 of Agriculture, gave the following percentages : Total dissolved solids, 

 31,6; soluble solids in cold water, 28,6; nontannins, 6,7; tannins, 20.1."
