Cassia × nealiae Irwin & Barneby, nom. nov. C. fistula x javanica Neal, In Honolulu Gardens 145. 1929.—. . [Hawaii, Oahu: Honolulu]. . . . with pinkish-orange flowers at 1060 Lunalilo Street . . . with cream-colored flowers at Kamanele Park, others at 1543 and 1555 Pensacola Street."—No typus known to exist, but Degener 7267 (NY) from Kamanele Park, the Rainbow Shower mentioned by him under C. javanica in Fl. Hawaiiensis, is considered authentic.

Cassia fistula x javanica sensu Neal, In Gardens of Hawaii 372. 1948.

Intermediate between the supposed parents in size of lfts; bracts more persistent than those of C. fistula, and the raceme-axis stiffer; petals persistent after fall of androecium and calyx, as often in C. fistula, but ± suffused with pink coloration of C. javanica; filaments of 3 long stamens not nodular; pod not seen, said by Degener to take full form but to bear only barren seeds.

A highly decorative ornamental tree, said by Degener (in annotation of specimens, NY) to have been raised by David Haughs, and now existing in several color-forms. The parentage is known only from tradition, but seems altogether plausible morphologically, the javanica forebear being presumably var. indochi- nensis, commonly cultivated in Hawaii.
