这里对来自安蒂奥基亚省（哥伦比亚）的 Burmeistera fisulosa 和 B. relinata 进行了描述和说明。第一种与 B. tomentosula 相似，不同之处在于表面无毛、叶柄长 1.4-2 厘米、叶片椭圆形至卵形、下伏叶减少、萼裂片 2.5-3.5 x 0.8-1.2 毫米、腹侧花药具须状、白色、倒圆锥形至椭圆形浆果。第二种与 B. diazii 相似，不同之处在于狭卵形的叶子，有 5-6 对次脉和下面不明显的高级脉，花无毛，萼裂片 5-9 x 0.6-1 毫米，花冠长度的一半或更短，腹侧花药有须须，白色浆果布满酒纹。
Burmeistera fistulosa and B. reclinata, both from the department of Antioquia (Colombia), are here described and illustrated. The first species is similar to B. tomentosula, from which it differs by the glabrous surfaces, the petiole 1.4–2 cm long, the lamina elliptic to ovate, the reduced subtending leaves, the calyx lobes 2.5–3.5 x 0.8–1.2 mm, the ventral anthers barbate, and the white, obconic to ellipsoids berries. The second species is similar to B. diazii, from which it differs by the narrowly ovate leaves with 5–6 pairs of secondary veins and higher order veins inconspicuous beneath, the glabrous flowers with calyx lobes 5–9 x 0.6–1 mm, half of the corolla length or less, the barbate ventral anthers, and the white berries suffused with vinaceous lines.
