In some instances the roots of the nurse plants show no appreciable cessation of growth after the tops of the plants have been removed. One would expect that in such event the roots of the inarched mango- steen seedlmgs would not be well developed, but as a matter of fact they are much superior to those of an uninarched seedling of the same age (PI. VII), proving that as a result of the union the mango- steen is nursed along during the critical period of its existence in a. Fig. 14.—(Jroup of niunKostecn .seedlings inarched by the method. The tops of the nurse plants have been removed. most satisfactory wa}'. This undoubtedly indicates that the mango- steen needs treatment of this nature to bring it through the early seedling stages, because the roots of the uninarched seedlings, espe- cially within a year after germinating, are never robust, and too much or too little water produces bad effects. Those plants, how- ever, which were inarched on other sj)eci(\s of Garcinia by the seed- ling-inarch method seem to thrive well when subjected to the treat- ment usually accorded inarched mangos. Although our expcM-inients in inarching the mangosteen on nurse plants have turned out veiy satisfactorily, not a plant being lost, the method first used has been improved considerably, so that there is now less danger from careless work. The nurse plants of Garcinia tinctoria should be grown in small-sized j)ots, not hirger 202. Please note that these i
