Description:Latin Diagnosis - Arbor 8-10 m alta ramis ramulisque glaberrimis. Stipulae geminatae. Folia imparipinnata coriacea 6-7-juga, glabra, rachi 16 cm longo intemodiis 2 cm longis; stipellis geminatis; petioluli laterales 3-8 mm, terminates 12-15 mm longi; laminae foliolorum elliptico-oblongae basi subobtusae apice breviter attenuatae subobtusae vel subacutae, margine moderate crenatae, 8-13 × 2.7 cm, adaxiale nervatione discolori conspicua venis reticuloque lutescenti leviter prominulo, abaxiale costa valde prominenti nervis secundariis (13-) 14-17(-20) utroque latere patulis valde tenuibus leviter prominulis, reticulo venulorum laxo saepe parum notato vel obsoleto superficie viridi-cinerea minutissime papillosa. Paniculae femineae fructiferae ca. 8 cm longae ramis ramusculisque glabris. Flores 2 pentameri; calyx complanatus 7 mm diam., lobi 3 x 1.8 mm; staminodia 10, 0.8-1 mm longa; folliculi ovoideo-ellipsoidei apiculato 8 × 5 mm, copiosissime setosi setis rigidis 1-1.8 mm longis endocarpio ellipsoideo uno latere acuto 7 × 4 mm, in sicco aperto subolliformi 4 × 4(6.5-4.5) mm; semina oblongo-elliptica 3 × 1.61.8 mm, rubro-brunnea sublaevia nitidissima.

Discussion:Subspecies caucana differs from the typical subsp, littlei from the Eastern Cordillera in Huila, by the longer, larger and more rigid leaves, the leaflets being longer with usually 14-17 (up to 20) pairs of lateral nerves; the venular reticulum is very conspicuous and prominulous adaxially and obsolete or ± noticeable abaxially. Additional collections of the population of this taxon are needed for better understanding.
