From the donor's notes: "Identification was determined by the general appearance of the tree, examination of the leaf, pinnae, spine, and fruitstalk. A close examination of the khalal stage fruit and the seed was most revealing. The characteristics of this tree very closely match the descriptions and pictures in Nixon's book. Scott Frische was present at the time of identification and concurred." <P>Thus, the identity of this tree is not certain. It should be observed and further compared to published descriptive material. It was received as offshoots (basically small plants, therefore coded as PL in the ACFORM field).

It thus appears that both RPHO 22 and RPHO 23 are legitimate 'Kustawy' but some morphological observations should be made. (RR Krueger, 2013-05-20)
