Burmeistera，Centropogon和Siphocampylus共同组成了新热带区特有的500多个种，目前对这些属的认识是不令人满意的，还有很多多样性有待描述。在过去的七年里，每28个用于鉴定的标本中就有一个代表了一个新物种，其中许多具有独特或不寻常的特征。Siphocampylus smilax（玻利维亚）是该属植物中唯一的一种，其叶脉平行走向，花外蜜腺发达。秘鲁的Centropogon diaperus不能归入任何已知的属下分类群，因此建议将其归入一个新的组：Centropogon sect. Niveopsis。steinii（Ecuador）是该属中最小的，而C. connatilobatus（Venezuela）是第一个将丛枝状短柔毛和合生萼裂片结合在一起的种。Burmeistera venezuelensis是委内瑞拉已知的第二个物种，也是第一个特有的物种;同样，Centropogon wilburii是墨西哥已知的第三个Centropogon物种，也是该国第一个特有的物种。还描述了额外的新颖性。
Burmeistera, Centropogon, and Siphocampylus together comprise more than 500 species endemic to the Neotropics, Current knowledge of these genera is unsatisfactory, with much diversity yet to be described. Over the past seven years, one out of every 28 specimens received for identification has represented a new species, many characterized by unique or unusual character states. Siphocampylus smilax (Bolivia) is unique in the genus in its parallelodromous leaf venation and extra-floral nectaries. Centropogon dianae (Peru) cannot be accommodated in any recognized infrageneric taxon, and a new section, Centropogon sect. Niveopsis, is proposed for it. The flowers of C. steinii (Ecuador) are the smallest known in the genus, while C. connatilobatus (Venezuela) is the first species to combine arbusculiform pubescence and connate calyx lobes. Burmeistera venezuelensis is only the second species of the genus known to occur in Venezuela and the first to be endemic; similarly, Centropogon wilburii is only the third species of Centropogon known from Mexico and the first to be endemic to that country. Additional novelties are also described.
