描述了玻利维亚干旱河谷特有的Gomphrena属两个新种的形态、花粉特征和地理分布。Gomphrena fuscipellita是一种多年生植物，与Gomphrena的所有其他物种的不同之处在于其外倾的习性，通常二歧分枝的茎，浓密的黄棕色毛被和具有大的总苞片的复合花序。Gomphrena mizqueensis是一年生植物，形态上与Gomphrena mizqueensis相似。pallida、白腹隐翅虫G. phaeotricha和G.铁氟龙与这三种不同的是，它的直立习性在其上半部分分枝，花被片具牙齿的先端，舟状，顶部具牙齿的苞片，和卵形的叶有一对明显的侧脉。
Morphology, pollen characters, and geographical distribution as currently known are described for two new species of Gomphrena, both endemic to dry valleys of Bolivia. Gomphrena fuscipellita is a perennial, differing from all other species of Gomphrena by its decumbent habit, generally dichotomously branching stems, dense yellowish brown indumentum, and compound inflorescences with large involucral bracts. Gomphrena mizqueensis is an annual, morphologically allied to G. pallida, G. phaeotricha, and G. ferruginea. From the three it differs by its erect habit branching in its upper parts, tepals with dentate apex, cymbiform, apically dentate bracts, and ovate leaves with one conspicuous pair of lateral veins.
