The correct name for a section of Ludwigia L. (Onagraceae)
In 1953, Hara provided new combinations for many sectional and species names when he combined Jussiaea L. with Ludwigia L., and at the time, Ludwigiasect.Oligospermum (Micheli) H.Hara was the correct name for one well-defined section. However, subsequent changes to/clarifications of the botanical code have necessitated a change for that name in that now an autonym is treated as having priority ...

متن کاملComplete Plastome Sequence of Ludwigia octovalvis (Onagraceae), a Globally Distributed Wetland Plant
Here, we present the first plastome of Ludwigia octovalvis (Onagraceae, Myrtales) as well as the first plastome in the subfamily Ludwigioideae. This genome is notable for its contracted inverted repeat regions and an expanded small single-copy region compared to other species in the orders Myrtales and Geraniales.
متن کاملEffect of seed age and soil texture on the germination of some Ludwigia species (Onagraceae) in Nigeria
Seed germination in Ludwigia was greatly influenced by seed age and soil type. In Ludwigia abyssinica germination was not influenced by seed age and soil texture. Freshly shed seeds and six month old seeds of Ludwigia decurrens variety B showed a very low percentage germination on all the germination media, and six month old seeds germinated significantly earlier than freshly shed seeds. Some s...
متن کاملThe evolution of viviparity and placentation revisited.
Most studies on the evolution of viviparity in squamate reptiles have focused on one or more of the following questions: (1) what selective force(s) are involved in the transition from oviparity to viviparity? (2) how does this transition occur (i.e., what changes are involved)? and (3) how and when does placentation evolve? In answer to the first of these questions, most studies have implicate...
