Growth habit of two types of sprangletop (Leptochloa chinensis Nees), the prostrate type and the fasciculate type, was investigated under different seeding times and moisture conditions. 1) The fasciculate type plants headed 40〜50 days after emergence regardless of emerging timing, and their flowering period continued from middle June to middle October. The prostrate type plants headed from late August to early September and their flowering period was from early September to middle October. 2) The original plant type and growth habit were maintained in the second generation either in upland condition or wet condition. From the results, it is concluded that these two types are genetically different variants. These variants seem to be isolated in reproduction, because they showed the different flowering period when emerged from April to June. 3) From the growth habit and distribution in fields, it is suggested that the prostrate type plants are adaptable for arable land and the fasciculate type plants are adaptable mainly for unarable upland field.
