Description:
Species Description - Medium-sized tree of glabrate aspect with spreading branches. Leaves large, leafstalk (1-) 1.5-4 dm, eglandular; leaflets 3-7(-8) pairs, petioluled (to 5 mm), ovate to lanceolate, larger upwards, (5-)7-20 cm, the terminal 2-2.8 r, proximal 1.2-2.5 r, coriaceous, initially finely puberulent. Stipules not seen, said to be 1 -2 mm. Flowers in pendent, usually clustered, axillary (leaves absent at anthesis or not), lax racemes, (2-)3-4 dm, without persistent bracts. Pedicels slender, 3-5 cm; sepals subequal, elliptic, 7-9 mm; corolla pale to bright yellow, (3-)4-6 cm diam; stamens 10 with filaments longer than anthers, the lower 3 much exserted with long arching medially thickened but not nodose filaments to 2.5 cm, the upper 3 smallest. Legume indehiscent, persistent, linear-cylindric, (1 —)3—5 dm long, 1.5-1.7 cm diam; valves at first pulpy-syrupy becoming woody, glossy brown to black, not ribbed, transversely segmented within. Seeds many.

Discussion:
CN n = 14 (Irwin and Turner, 1960; Pantulu, 1960; Bir and Sidhu, 1967). And others with base 14. n = 12 (Tischler, 1921-22). The virtues of Cassia fistula in Florida are rhapsodized by Menninger (1958) and Barrett (1956). Avery (in litt.) says it is fairly common in the Miami area and Key West. Counts of several workers including Pantulu’s (1960) “repeated determinations” of n = 14 are confirmatory. A Bir and Sidhu (1966) report of n = 13 was corrected (Bir, 1967) to n = 14. There has been no confirmation of Tischler’s old count.
