Ginkgo biloba 'Pyramis' we believe is an introduction from Hungary, however some sources consider it to be syn. with 'Pyramidalis'. There are some similarities in respect of habit between 'Pyramis' and 'Pyramidalis' however on the specimens we have in the National Collection of Ginkgo biloba & Cultivars the foliage is quite different on each and Pyramis is much slower in growth, some go as far to as calling it a dwarf.
 
Description - The leaves can be striking and variable, some trilobed, some bi-lobed, some irregular and many often needle shaped, as can be seen in the images. The growth rate too is quite variable and that depends on what part of the plant is measured. Where very fine leaves are produced it is usually 20 cm per annum in other areas it can be as much as 45 cm. In the early stages of growth, the plant retains a leader, the branches arise at 45 degrees and droop with age.
