Leaves with 5–7(–9) pairs of pinnae; (5–)6–10(–17) pairs of leaflets; rachis nectary 1, verruciform; blade chartaceous, margin glabrous, leaflets (4–)6–10(–13) × 3–7 mm, discolor, glabrous on both surfaces, unilateral tuft of trichomes on the lower surface absent.

Distribution and habitat: — Stryphnodendron cristalinae occurs in campo limpo, campo sujo, campo cerrado or in more open physiognomies of the cerrado, often associated with sandy or rocky soils. The species has a very restricted distribution, being known only in the municipality of Cristalina (Goiás state), from the Serra dos Cristais and sometimes reaching the limits of urban areas. The specimens collected at the Água Limpa farm (University of Brasília Experimental Station, Brasília, Federal District) were cultivated from seeds brought from Cristalina.

Conservation:—Endangered (EN B1ab(i,iii)+2ab(ii,iii) [AOO= 12.000 km 2, EOO= 1,021.914 km 2]. Only small populations of this taxon were found during recent expeditions to its area of occurrence, in extremely reduced areas bordered by soybean plantations. No records in conservation units were found.

Phenology: —This species was collected with flowers in March to May, and July to January. Specimens with fruits were collected in March, April and November.

Selected specimens examined: — BRAZIL. Goiás: Cristalina, ao longo da BR 050, 7 km ao sul do entroncamento com a BR 040, 20 September 2016, fl., R.C. Pires & M.F. Simon 100 ( CEN).
