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, mariigoba 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 Sab 
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.)
