Manihot spp. (Euphorbiaceae . ) 39337-340. Seeds of 

 manigoba rubber trees from Bahia, Brazil. Presented by 

 Dr. V. A. Argollo Perrao. "The good name that Jequie rub- 

 ber had was on account of being prepared in sheets and 

 pure, because the Manihot dichotoma is tapped on the bark 

 in 'porangos (tins)' like Hevea, so such rubber is clean 

 from impurities and is easily prepared in thin sheets of 

 nice appearance. Manihot heptaphylla (Rio Sao Francisco 

 zone) and Manihot piauhyensis (State of Piauhy) being tapped 

 near the roots, if not tapped carefully, give rubber that 

 have large proportions of sand and clay. As to quality 

 the Jequie is the worst, for it has resins and less elas- 

 ticity. Growers who planted M. dichotoma succeeded badly 

 because the growth of the trees is extraordinarily vari- 

 able. Seedlings from the same tree show an extraordinary 

 variability of leaves and growth. M. dichotoma requires 

 at least six years as a rule before tapping. The best va- 

 riety for plantations is M. piauhyensis, for it gives the 

 best rubber, and can be tapped at three years (even at two 

 under good conditions.) With low prices of manigoba rub- 

 ber, manigoba can only give profits if labor is very 

 cheap, not exceeding thirty cents per day. Manigobas will 

 not stand frosts (I have seen some severely injured in Sao 

 Paulo by slight frosts in coffee districts.) Manigoba re- 

 quires a rainy season in summer. The M. heptaphylla and 

 M. dichotoma are found in parts of the state of Bahia on 

 the other side of the chain of mountains that divide the 

 state in two climates. Between mountains and sea, rains 

 occur during winter, and on the other side, from mountains 

 to Rio Sao Francisco rainfall is in summer. Manigoba 

 grows in the second zone if planted but does not give much 

 rubber nor good quality, as Villa Nova plantations show, 

 although trees have the best appearance. (Villa Nova is 

 on the mountain that divides the climatic zones of the 

 states. In mountains you have rains in summer and 'neb- 

 lines' (fog rain) in winter). In the manigoba districts 

 there are heavy rains during summer for four to six 

 months, such rains may last for ten days, day and night. 

 There are no rains during the dry season and from time to 

 time, about once in ten years, the summer rains fall. In 

 our state people who have manigoba forest or plantations, 

 are investing in cotton because the low price of rubber 

 does not give enough profits to pay for tapping trees. 

 Manigoba will not stand stagnant water." (Argollo Ferrao.)
