Garcinia aff. dulcis "Russell's Sweet" Seeds

Garcinia aff. dulcis "Russell's Sweet" is thought to be an improved variety of Garcinia dulcis (strong grafting compatibility) or possibly a closely related but separate undescribed species.  The first documented specimen was collected from Bangkok, Thailand in 1987 during a trip by Australian collector Russell Francis (now deceased) and was grown out in Northern Australia.  The fruit looks like a Garcinia dulcis but the fruit is significantly larger and said to be consistently much sweeter with around 75% pulp weight.  The taste was described by Russell Francis as "sweet yellow peach coupled with that distinctive mangosteen tang".  Russell grew out a handful of trees which first flowered at 6-7 years old but other collectors in Australia have fruited it at 4-5 years old.  The fruit is dioecious but lone females trees will produce a small amount of small sized seedless fruit.  Pollinated females will produce large quantities of large fruit with seeds.  The fruit ripens June-July in the southern hemisphere and December-January in the northern hemisphere.  The seeds weight 6.4 grams on average.
