The genus Ctenium (Poaceae: Chloridoideae: Chlorideae) in Africa

Kew Bulletin, 2014
The genus Ctenium Panzer includes c. 20 species from tropical Africa and the Neotropics. A survey of the African species was carried out, based mainly on the study of herbarium material, and resulted in the confirmation of eight species: C. canescens Benth., C. concinnum Nees, C. elegans Kunth, C. ledermannii Pilg., C.

A Fossil Grass (Gramineae: Chloridoideae) from the Miocene with Kranz Anatomy

Science, 1986
A fossil leaf fragment collected from the Ogallala Formation of northwestern Kansas exhibits features found in taxa of the modern grass subfamily Chloridoideae. These include bullet-shaped, bicellular microhairs, dumbbell-shaped silica bodies, cross-shaped suberin cells, papillae, stomata with low dome- to triangular-shaped subsidiary ...

Synopsis of the genus Tragus (Poaceae: chloridoideae: cynodonteae) in Peru

Phytotaxa
A taxonomic synopsis of the genus Tragus for Peru is presented. Tragus peruvianus is described as a new species, while T. australianus and T. racemosus are excluded from the Peruvian agrostological flora. A taxonomic key, morphological descriptions, ecological information, notes, iconography, and reference images are provided.

Chromosome studies in the grass subfamily Chloridoideae. II. An analysis of polyploidy

TAXON, 2003
Polyploidy is frequent among the grasses. This study indicates that it has a high frequency in the subfamily Chloridoideae, where more than 90% of the studied specimens are polyploids. These levels range from diploid (2n= 20 forx= 10 and 2n= 18 forx= 9) to 16‐ploid (2n= 160) forx= 10 inCtenium concinnumNees and 20‐ploid (2n= 180) forx= 9 inHilaria ...

PROLAMIN AND IMMUNOLOGICAL STUDIES IN THE POACEAE. III. SUBFAMILY CHLORIDOIDEAE

American Journal of Botany, 1993
Prolamin size variation and structural similarities were used as molecular characters to address questions pertaining to tribal structure and phylogenetic origin of the Chloridoideae. Prolamin polypeptides were resolved by SDS‐PAGE (sodium dodecyl sulphate polyacrylamide gel electrophoresis), and the immunological cross‐reactivities were measured by ...

Salinity Tolerance Mechanisms of Grasses in the Subfamily Chloridoideae

Crop Science, 1999
Forage grasses and turfgrasses are increasingly being subjected to salinity stress, due to accelerated salinization of irrigated agricultural lands worldwide, and to increased use of reclaimed and other secondary water sources for irrigating turfgrass landscapes.

A Cytological Difference between the Eupanicoideae and the Chloridoideae (Gramineae)

The Southwestern Naturalist, 1960
Examination of chloroplast distribution in the parenchyma sheath cells of 59 species of panicoid grasses has revealed that the Euphanicoideae and the Chloridoideae differ for this character. In all 28 species of the Eupanicoideae the chloroplasts, when devoid of starch, are grouped in the outer (centrifugal) region of the parenchyma sheath cells. Among
