Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Argyreia nervosa is a perennial climbing vine native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa, and the Caribbean. Though it can be invasive, it is often prized for its aesthetic and medicinal value. Common names include Hawaiian baby woodrose, adhoguda अधोगुडा or vidhara विधारा (Sanskrit), elephant creeper and woolly morning glory. Its seeds are known for their powerful entheogenic properties, greater or similar to those of Ipomoea species, with users reporting significant psychedelic and spiritual experiences. The two botanical varieties are A. n. var. nervosa described here, and A. n. var. speciosa, which are used in Ayurvedic medicine for their medicinal value.
Verticillium is a genus of fungi in the division Ascomycota, and are an anamorphic form of the family Plectosphaerellaceae. The genus used to include diverse groups comprising saprobes and parasites of higher plants, insects, nematodes, mollusc eggs, and other fungi, thus the genus used to have a wide-ranging group of taxa characterised by simple but ill-defined characters. The genus, currently thought to contain 51 species, may be broadly divided into three ecologically based groups - mycopathogens, entomopathogens, and plant pathogens and related saprotrophs. However, the genus has undergone recent revision into which most entomopathogenic and mycopathogenic isolates fall into a new group called Lecanicillium.
The yellow-throated bulbul is a species of songbird in the bulbul family of passerine birds. The species is endemic to southern peninsular India. They are found on scrub habitats on steep, rocky hills many of which are threatened by granite quarrying. It is confusable only with the white-browed bulbul with which its range overlaps but is distinctively yellow on the head and throat apart from the yellow vent. The calls of this species are very similar to that of the white-browed bulbul.

It is a narrow-leaved, tropical paperbark with yellow-green and red-flowering forms. As with some other melaleucas, this species has many uses to Indigenous Australians.
