This information is basic by design and does not include total botanical information about each species (kind of tree).  Rather, only more or less easily observable features, mostly throughout the seasons, of each numbered tree in the Alabaster Bike Path-Native Tree Arboretum (ABP-NTA) are listed.  Some of the species have distinctive flowers and fruits which are listed; however, many trees have years of heavy flowering / fruiting and years of little or no flowering / fruiting.   Because all natural populations have variation, it is best to look at several examples of each characteristic.    All photos (except where noted) and all text by sczaika.  Historical uses from Hough, R.B.  The Wood Book.
