The specimens collected in the Santana do Pirapama region (D. Zappi 1681 et al. and D. Zappi 2343 et al.) show distinct characters then those found in specimens from the Serra do Cipó population, like the more densely arranged spines (1.5– 1.2 mm vs. 3–6.7 (7.7) mm) and the lower floral bracts longer than pedicels (vs. shorter than pedicels).</p> <p>The density of leaf trichomes varies according to the habitat and altitude in D. macedoi (Table 6). Populations may also differ from one another in terms of whether they form clumps or not. Individuals from Serra do Estreito often form clumps, while those from Serrinha and at km 5 of road MG-010 usually remain isolated under the shadows of subshrubs.</p> <p>Style size also varies in these populations. At Serrinha and km 5 of MG-010, individuals have subsessile stigma and very narrow styles. Additional studies on their reproductive biology are needed for a better understanding of these differences.</p> <p>soil type.</p></div> 	https://treatment.plazi.org/id/03873848420CFFF1FF0DF890FF7AF9A8	Public Domain	No known copyright restrictions apply.

These areas are severely affected by annual fires. Dyckia oligantha does not occur in Conservation Units.</p> <p>Comments:— Dyckia oligantha was described based on a specimen from Serra do Cipó. For four decades it remained known only from the type collection and was considered a synonym of D. saxatilis by Forzza &amp; Wanderley (1998) and Versieux &amp; Wendt (2006). However, D. oligantha differs morphologically from D. saxatilis by having a lower mean flowering plant height (25.1 cm vs. 52.9 cm); asymmetric rosettes with recurved leaves (vs. symmetric rosettes with straight leaves); slender (vs. robust) and longer pedicels (ca. 5.2 mm vs. ca. 2.5 mm), relative longer pedicel to total flower length ratio (40% vs. 19.2%), convex sepals (vs. not convex), and filaments free above the petal-stamen ring (vs. connate).</p> <p>Inflorescences with more than five flowers have their apical half curved, with slightly secund flowers. Floral bracts enfold half of the pedicel diameter.</p> <p>Rauh (1988) described D. oligantha var. cristalina (syn. nov.) from Goiás state, Brazil. However, after analysis of the type material, we found that the variety is similar to D. machrisiana L.B. Smith (1957b: 7).</p> <p>Guarçoni et al. (2010) revalidated D. oligantha, but erroneously indicated the collections numbers Guarçoni 1241, 1273, 1274, and 1281. Those collection numbers actually represent D. consimilis Mez, which is not morphologically related to D. oligantha.
