Nepenthes deaniana (/n[invalid input: 'ɨ']ˈpɛnθiːz ˌdiːniˈɑːnə/; after Dean C. Worcester) is a tropical pitcher plant endemic to the Philippines, where it grows at an altitude of 1180–1296 m above sea level.[3] The species is known only from the summit region of Thumb Peak, a relatively small, ultramafic mountain in Puerto Princesa Province, Palawan.
Nepenthes deaniana has no known natural hybrids.[3] No forms or varieties have been described.
In his Carnivorous Plant Database, taxonomist Jan Schlauer treats N. gantungensis, N. leonardoi and N. mira as heterotypic synonyms of N. deaniana.[4]
Adolph Daniel Edward Elmer recorded a plant from Mount Pulgar (now known as Thumb Peak) matching the description of N. deaniana. He made mention of this discovery in the April 20, 1912 issue of Leaflets of Philippine Botany, in his formal description of N. graciliflora:[5]
Recently the writer [Elmer] observed a large sterile species on mount Pulgar of Palawan. Some of its pitchers were a foot long and six inches thick!
Botanical history
The members of the Palawan Mountaineers who climbed Thumb Peak in 1993 actually took photos of N. deaniana and included it in their photo exhibit the same year, not knowing the identity of the plant.[citation needed]
Description
Unlike most Nepenthes species, N. deaniana does not climb. The stem is 20 to 30 cm tall, 4 to 5 cm wide, and glabrous throughout. Plants spread by means of shoots. Leaves are lanceolate or obovate in form, 6 to 12 cm long, and 3.5 to 4 cm wide. They possess 4 to 5 pairs of longitudinal veins, connected by irregularly reticulate transverse veins. Tendrils are 10 to 15 cm long.[2]
Pitchers are obconic, 6 to 9 cm high, and 2.3 to 3.5 cm wide. The peristome is cylindrical and 5 to 8 mm wide, bearing long attenuate teeth on its inner margin. The operculum or lid of this species is broadly cordate.[2]
The male inflorescence is 15 to 20 cm long and may be pubescent to glabrous. Pedicels are 1-flowered, compressed and expanded at the base. Individual flowers have 4 sepals and 8 anthers.[2]
