All of the credit for this confirmation of this _Capparis lanceolaris_ identification goes to the Au Tropical Herbarium botanists (... ...), today 2026 Feb. 20th . Thank you to them !

Should be Eriochilus magenteus out that way. E. cucullatus isn't very common out that way and tends to be whiter, although there is a lot of overlap in colour between the two species.
