Panicum sensu stricto is a genus of grasses (Poaceae) with nearly, according to this study, 163 species distributed worldwide. This genus is included in the subtribe Panicinae together with Louisiella, the latter with 2 species. Panicum and subtribe Panicinae are characterized by including annual or perennial taxa with open and lax panicles, and spikelets with the lower glume reduced; all taxa also share a basic chromosome number of x = 9 and a Kranz leaf blade anatomy typical of the NAD-me subtype photosynthetic pathway.

- Tribe Eudemeae includes seven diverse genera found along the Andes, showcasing a wide range of characteristics in growth, flowers, and fruits.
- Research indicates strong phylogenetic ties within the tribe, revealing a split into two main lineages based on geographic and climatic factors.
- The study highlights multiple independent changes in key morphological traits throughout the tribe's evolution, with important implications for taxonomy.
Article Synopsis
- The tribe Paniceae s.l. is one of the largest groups within the Panicoideae subfamily of the Poaceae family, featuring over 2000 species with extensive diversity in morphology, cytology, and physiology.
- Recent molecular studies have shown that this tribe is paraphyletic, revealing two main clades based on chromosome numbers (x=9 and x=10), with their relationships to other tribes like Andropogoneae and Arundinelleae.
- A comprehensive analysis involved 155 genera from the Panicoideae subfamily, incorporating genetic data and morphological traits to clarify phylogenetic relationships, emphasizing the significance of chromosomal structure in understanding tribal classifications.
© The Willi Hennig Society 2010. ABSTRACT: The tribe Stipeae, with nearly 550 species, includes 28 core genera, of which 13 occur in America: Achnatherum, Aciachne, Amelichloa, Anatherostipa, Hesperostipa, Jarava, Nassella, Ortachne, Oryzopsis, Pappostipa, Piptatherum, Piptochaetium and Ptilagrostis. Based on 37 species representing 14 Stipeae genera, and using four chloroplast markers and morphological characters, we provide a phylogenetic hypothesis of the New World Stipeae, with our focus on Amelichloa and Aciachne.
View Article and Find Full Text PDFThe subtribe Melinidinae (Poaceae: Panicoideae: Paniceae) includes 14 genera that present the PCK photosynthetic subtype in addition to several other unique and also common characters. The purpose of this research was (1) to test the monophyly of the subtribe Melinidinae, including 331 ndhF sequences of Panicoids and related genera, (2) to analyze the phylogenetic relationships among genera of Melinidinae using four cpDNA regions, and (3) to study evolutionary trends in the homogenization of inflorescences. As a result, the monophyly of Melinidinae is supported if Urochloa venosa is excluded from the subtribe.
