چکیده
A new species of Hoya R.Br. from Sulawesi (Indonesia), Hoya isabelchanae Rodda & Simonsson, is described and illustrated. It is one of the largest flowered species in Hoya section Acanthostemma (Blume) Kloppenb. Its flowers are of comparable size to those of Hoya benchaii Gavrus et al., Hoya kloppenburgii T.Green, Hoya rundumensis (T.Green) Rodda & Simonsson and Hoya sigillatis T.Green ssp. sigillatis, all from Borneo. Among Sulawesi species it is compared with the vegetatively similar Hoya brevialata Kleijn & van Donkelaar and Hoya pallilimba Kleijn & van Donkelaar.

Two new Hoya R.Br. species from Borneo are described and illustrated. The first, Hoyaruthiae Rodda was collected in Sabah on Bukit Baturong, a limestone outcrop. It is one of the few species in the genus to have clear exudate. It is compared with the morphologically related Hoyauncinata Teijsm. and Binn. The other, Hoyabakoensis Rodda, was collected in the kerangas forests of Bako National Park...

Jasminanthes xuanlienensis (Apocynaceae, Asclepiadoideae), a new species from Vietnam is described, illustrated and compared with its five congeners. Jasminanthes xuanlienensis differs distinctly from congeners by the longer peduncles (14-18 cm vs. 4 cm at most in Jasminanthes pilosa and Jasminanthes saxatilis, salmon-pink color of the inner corolla lobes (white or greenish in the other species...
متن کاملWax plants disentangled: a phylogeny of Hoya (Marsdenieae, Apocynaceae) inferred from nuclear and chloroplast DNA sequences.
Hoya (Marsdenieae, Apocynaceae) includes at least 200 species distributed from India to the Pacific Islands. We here infer major species groups in the genus based on combined sequences from the chloroplast atpB-rbcL spacer, the trnL region, and nuclear ribosomal DNA ITS region for 42 taxa of Hoya and close relatives. To assess levels of ITS polymorphism, ITS sequences for a third of the accessi...

PREMISE OF THE STUDY To examine patterns of genetic diversity and test possible hybridization events, microsatellite markers were identified and characterized in Hoya ledongensis (Apocynaceae), and cross-amplification was tested in a congener, H. jianfenglingensis. METHODS AND RESULTS Based on the transcriptome data of H. ledongensis, 46 microsatellite primer pairs were randomly selected for ...
