Philodendron is a large genus of flowering plants in the family Araceae. As of September 2015, the World Checklist of Selected Plant Families accepted 489 species; other sources accept different numbers. Regardless of number of species, the genus is the second-largest member of the family Araceae, after genus Anthurium. Taxonomically, the genus Philodendron is still poorly known, with many undescribed species. Many are grown as ornamental and indoor plants. The name derives from the Greek words philo- 'love, affection' and dendron 'tree'. The generic name, Philodendron, is often used as the English name.
Alocasia is a genus of rhizomatous or tuberous, broad-leaved, perennial, flowering plants from the family Araceae. There are about 90 accepted species native to tropical and subtropical Asia and eastern Australia. Around the world, many growers widely cultivate a range of hybrids and cultivars as ornamentals.
Caladium is a genus of flowering plants in the family Araceae. They are often known by the common name elephant ear, heart of Jesus, and angel wings. There are over 1000 named cultivars of Caladium bicolor from the original South American plant.
Nepenthes campanulata, the bell-shaped pitcher-plant, is a tropical pitcher plant native to Borneo. It has also been reported from Palawan, the Philippines, though further field work is needed to confirm this identification.
The dwarf wych elm cultivar Ulmus glabra 'Nana', a very slow growing shrub that with time forms a small tree, is of unknown origin. It was listed in the Simon-Louis 1869 catalogue as Ulmus montana nana. Henry (1913), referring his readers to an account of the Kew specimen in the journal Woods and Forests, 1884, suggested that it may have originated from a witch's broom. It is usually classified as a form of Ulmus glabra and is known widely as the 'Dwarf Wych Elm'. However, the ancestry of 'Nana' has been disputed in more recent years, Melville considering the specimen once grown at Kew to have been a cultivar of Ulmus × hollandica.

Alocasia melo is a species of flowering plant in the family Araceae, native to Sabah state in Malaysia. It grows on ultramafic soils. In the houseplant trade it is often sold as "Alocasia rugosa" due to its highly rugose leaves.
Alocasia scalprum, the Samar lance, is a species of flowering plant in the family Araceae, native to Samar island, the Philippines. Well known from cultivation as a houseplant in the Philippines, and introduced to aroid enthusiasts as Alocasia cv. Samar Lance in 1984, it was not formally described as a species until 1999. Its glossy, lance-shaped leaves with embossed veins take on a blue sheen when mature. It is similar in appearance to Alocasia heterophylla.
Alocasia longiloba is a species of flowering plant in the family Araceae. It is the namesake of a species complex. The complex has a widespread distribution; Guangdong, Hainan, and southern Yunnan in China, mainland Southeast Asia, and western and central Malesia.
Alocasia chaii is a species of flowering plant in the family Araceae, native to Sarawak state, Malaysia. Occasionally cultivated for its coriaceous leaves that remain peltate even when mature, it is considered obscure even by Alocasia enthusiasts and is very rarely found in commerce.
Schismatoglottis prietoi is an aquatic and semi-aquatic plant species in the family Araceae. It is endemic to the Philippines in fast-flowing freshwater rivers in lowland forests. It is the only known species in the genus Schismatoglottis that can grow in a fully aquatic habitat. It is a small plant, growing only up to 2 to 8 cm tall. The pale green to green leaves are smooth and are around 3 to 4 cm long and 1 to 2 cm wide. They are oblong to elliptical in shape with sharply pointed tips and broadly wavy edges.

Macodes sanderiana(Kraenzl.) Rolfe is a species of South East Asian jewel orchid mostly recorded from New Guinea but is also found in the Solomon Islands and Vanuatu. This species has a long history of cultivation in Europe since the early 20th century and is prized for its ornamental leaves which are the largest in its genus. The leaves are dark green, the upper surface covered in an intricate network of veins in colors ranging from bright green to copper. In contrast, flowers are small and pallid so are often removed in cultivation. In nature, M. sanderiana grows in rainforests on the forest floor or lithophytically out of rock crevices. This species survives at a broad range of altitudes from close to sea-level, up to the lower boundary of the cloud forest. Exudates from the leaves of this orchid are traditionally used in New Guinea as eye drops for the treatment of myopia. M. sanderiana has not been assessed for the IUCN red list, however, as recently as the 1980’s this species was common in parts of its range within New Guinea.
