Hoya upoluensis Reinecke

Hoya upoluensis

Distribution:

Samoa: Savai’i (?), ‘Upolu

local names:

fue manogi – ‘Upolu / Samoa

~~~

This species, including a proposed f. minor, was described in 1898. The forma was later given variety rank as Hoya upoluensis var. minor (Reinecke) Rech. in 1910, it is said to be smaller in all parts than the ‘normal’ form. [1][2]

The plant obviously occurs on the islands of Savai’i and ‘Upolu, Samoa, Hoya savaiiensis Kloppenb. (not to be mistaken with Hoya samoensis ssp. savai’iensis Kloppenb.) described in 2009 as coming from Savai’i, may be the same species.

~~~

The supposed local name, fue manogi, means fragrant liana, and the flowers are indeed fragrant, they were used to scent coconut oil. [1]

Hoya pottsii J. Traill

Hoya pottsii

Distribution:

Samoa: Ofu, Olosega, Ta’u, Tutuila
Tonga: ‘Eua

local names:

fue sa – Samoa
fue selela – Samoa

~~~

The actual Hoya pottsii is obviously a Chinese endemic, so, does not occur anywhere else, the Samoan and the Tongan material thus cannot represent the same species.

The species, however, is mentioned in 1996 as being native to the island of ‘Eua, Tonga, and in 2006 as being native to American Samoa. [1][2]

Such material, originally identified as Hoya pottsii, was subsequently described as a new species, Hoya tiatuilaensis Kloppenb. in 2013. [3]

~~~

The true status of the plants (not being Hoya australis R. Br. ex Traill) occurring on Ofu, Olosega, Ta’u, Tutuila, and ‘Eua are still to be clarified.

The depiction below shows the true Chinese Hoya pottsii.

Hoya vitiensis Turrill

Hoya vitiensis

Distribution:

Fiji: Vanua Levu, Viti Levu
Samoa: ‘Upolu

local names:

wa dra – Viti Levu / Fiji
wa tabua damudamu – Viti Levu / Fiji

***

This species is supposed to be endemic to the Fijian Islands, where it is known from Vanua Levu and Viti Levu, however, this or a very similar species also occurs on some of the Samoan Islands. [1]

***

The same infamous person who constantly describes new Hoya species almost on a weekly basis, described a new subspecies of this species in 2019 (Hoya vitiensis ssp. parksii Kloppenb.), which he based on material from the island of, quote: “Piti Leveu”. I have not seen a specimen, and actually I don’t bother to do so, I’ve only seen the blurred photos of dried plant parts that are so typical for this author’s species ‘descriptions’.

The same author in the same paper described Samoan material of Hoya vitiensis as a new species, Hoya malata Kloppenb., after having identified it as Hoya chlorantha Rech. before …. [2]

The situation goes worse and worse.

~~~

This species occurs from Australia to western Polynesia, it is divided into several subspecies, of which two are known to occur within the Polynesian region. The nominate race occurs in Fiji as well as in Wallis & Futuna, while the other subspecies, Hoya australis ssp. tenuipes (K. D. Hill) P. I. Forst. & Liddle occurs in Samoa and Tonga.

The species probably hybridizes with other species, one such hybrid (with Hoya chlorantha Rech.) was described from Tutuila, Samoa as Hoya x tuafanua Whistler & Kloppenburg.
