Dear all, In the illustration of F.leucopyrus, the branchlets ends in thorn. Thorn is a modified branch or shoot. Whereas the 'spine' is a modified leaf or its part or even stipules. I have seen F. leucopyrus, which is one of the common members in a deciduous or semi evergreen forests in Kerala often with thorns. Accidently I came across the same species in evergreen forests , where the thorns are absent and ends with leafy branches. This may not be a constant taxonomic character (It is my opinion only).
