I thought the original Australian description for African Pride might be of interest to several people on this thread. I have included it word for word below. Please note that I was not able to include the picture plate mentiond because this is hand typed. However, it looks strikingly similar to the top picture posted by Skahn. Also, (for those who do not already know) Atemoyas are called Custard Apples in Australia and ripening times will be approximately 6 months off of Florida due to being in opposite hemispheres. Also of interest is that the description for Pink's Mammoth in the same book call it "knobby" while Gefner is described as "pointed."
"African Pride was promoted in Queensland in the 1950s by Langbecker's nursery, Bundaberg. It is said to have been introduced from South Africa, but may have originated in Israel as the cultivar Kaller.
The fruit is heart-shaped or conical, small to moderate size and usually contains more seeds in relation to flesh than Pink's Mammoth. The medium-thickness skin is smoother than Pink's Mammoth and bears a series of concave, U-shaped areas like thumb-print impressions with small protuberances (areoles) (plate 2). Skin appearence can vary even between fruit on the same tree. Some fruit can have small, pointed skin segments. This variation in skin appearence could be related to tree vigour.
African Pride produces significant yields in the third year after planting. Harvesting begins in early April in the Nambour district.
Aftican Pride is a reliable cropper but a large percentage of fruit can be small in a heavy crop. Fruit size can be improved by thinning and pruning. For details, see the section on pruning.
The fruit of African Pride is considered more presentable than that of Pink's Mammoth and is easier to pack. It can be presented in single-layer trays. The tree does not exhibit the strong terminal growth of Pink's Mammoth and so is more compact.
African Pride's early consistent bearing behavior makes it the easiest and most profitable cultivar to grow in all districts of Queensland suitable for custard apples. However, it must be managed carefully to produce fruit of good size.
African Pride is the most convenient cultivar for home gardeners, because it begins fruiting only two or three years after planting, and is a smaller tree than Pink's Mammoth."
