1. Guilandina Crista (L.) Small. A straggling or sprawling shrub, armed with 
hooked prickles, the foliage finely pubescent. Leaves 2-5 dm. long, the leaflets numerous, 
the blades ovate to oblong-ovate or nearly oblong, mucronulate, 1.5-3.5 em. long, rounded, 
truncate or subcordate at the base: stipules foliaceous : racemes or panicles 1-4 dm. long: 
bracts surpassing the pedicels, recurved: corolla dull yellow, 1-1.5 cm. broad : pods oval 
or oval-oblong, 5-7 em. long, prickly all over, obliquely short-beaked : seeds gray or lead- 
colored. [Caesalpinia Crista L. Guilandina Bondue L. G. Bonducella L.] 
In pine lands and hammocks, peninsular Florida and the Keys. Also in the tropics generally. 
. 2. Guilandina major (DC.) Small. Similar to G. Crista in habit. Leaves without 
stipules: leaflets with relatively large blades which vary from 4-8 cm. in length: seeds 
yellow. [G. Bonduc L., not L. Sp. Pl. Ed. 1. G. Bondue var. majus DC.] 
In sandy soil, peninsular Florida and the Keys. Also widely distributed in the tropics.

dular at the base : anthers opening lengthwise. Pods flat, narrow and more or less curved,
