SYSTEMATICS OF CLEMENSIELLA (APOCYNACEAE – ASCLEPIADOIDEAE)
Edinburgh Journal of Botany, 2009 The genus Clemensiella (Apocynaceae – Asclepiadoideae) is reported to include two species. Clemensiella mariae, a Philippine endemic, is redescribed, illustrated, and lectotypified. Its chromosome number (2n = 22) is reported for the first time. The recently described Hoya viracensis is synonymised with Clemensiella mariae.

Phylogenomics Reveals Deep Divergences and Cryptic Species Within a Rare Sand-Dwelling Milkweed, <i>Asclepias tomentosa</i> Elliott. [PDF]
Ecol EvolPhylogenomic analyses demonstrated that the rare milkweed, Asclepias tomentosa, exhibited deep divergences correlated with geography and revealed the presence of cryptic species. A new species, A. tonkawae, sp. nov., is described from the Texas populations. ABSTRACT Integrative taxonomy incorporates multiple data types to delineate and describe species

Darwin's ‘mystery of mysteries’: the role of sexual selection in plant speciation
Biological Reviews, Volume 98, Issue 6, Page 1928-1944, December 2023., 2023 ABSTRACT Sexual selection is considered one of the key processes that contribute to the emergence of new species. While the connection between sexual selection and speciation has been supported by comparative studies, the mechanisms that mediate this connection remain unresolved, especially in plants. Similarly, it is not clear how speciation processes

New Phytologist, Volume 239, Issue 4, Page 1490-1504, August 2023., 2023 Summary Kleptomyiophily, where flowers imitate wounded insects to attract ‘kleptoparasitic’ flies as pollinators, is one of the most specialized types of floral mimicry and often involves physical trapping devices. However, the diversity of pollinators and functional floral traits involved in this form of mimicry remain poorly understood.
