Slash pine P. elliottii Engelm. var. elliottii Little and Dorman was introduced into Queensland in 1925 and quickly became the major plantation species on the coastal lowlands of southeastern Queensland. Honduras Caribbean pine P. caribaea Mor. var. hondurensis Barr. and Golf. was introduced in 1948 and trial plantings established along the Queensland east coast soon proved its potential. Within a decade it formed an important part of the planting program at Bowenia (23.degree.07'S, 150.degree.45'E). To test its adaptability in southeastern Queensland a number of trials comparing Honduras Caribbean pine with slash pine was established around 1950. In this note the results of trials established at Toolara (26.degree.00'S, 152.degree.50'E) between 1948 and 1953 are reported and suggestions are made with regard to the correct siting of the 2 spp.
