Hoya aeschynanthoides Schltr. n. sp.; Epiphitica, dependens vel in ramis arborum decumbens, ramosa; ramis ramulisque filiformibus elongatus, flexuosis, hispidis, radicantibus, densius foliatis; foliis breviter petiolatis late ovato-ellipticis acutis, utrinque pilosis, 1.5 - 2.3 cm. longis, medio fere 1 - 1.8 cm. latis, petiolo hispidulo 0.3 - 0.5 cm. longo; cymis umbelliformibus breiter pedunculatis foliis vulgo brevioribus, pedunculo hispido 0.5 - 1 cm. longo, pedicellis hispidulis c. 0.5 cm. longis; floribus in genere inter minores, albus; calycis segmentis lanceolato-oblongis obtusis hispidis, vix 1.5 mm. longis; corolla rotata 0.5 cm. diametiente, usque infra medium 5-lobata, lobis ovato-triangulis obtusiusculis extus glabris, coronae phyllis dorso adscendentibus antheras superantibus, superne oblanceolatis antice rostratis, subtus oblongis excisis, profunde sulcatis; antheris trapezoideis, appendice hyalina triangula; stigmatis capite conico.
         Borneo: auf Bäumen am Long Dett im staatie Koetei (R Schlechter n. 13550, blühend im August 1901).
        Eine sehr characteristische Art, welche in ihrer Belaubung an einige Aeschynanthus-Arten erhnnert. Sie gehört in die Verwandtschaft der H. lacunosa Bl.

Translation: Epiphytic, hanging down or decumbent (prostrate with the tips rising upward) on tree branches, branched; branches and branchlets threadlike elongate, flexible, hispid, with aerial roots, densely leaved; with leaves shortly petioled, broad ovate-elliptic, acute, pilose (felt like) on both sides, 1.5-2.3 cm. long, nearly 1-1.8 cm. wide, petiole hispid 0.3-0.5 cm. long; cymes shaped like umbels, briefly hispid about 0.5 cm. long; flowers in general rather small, white; with the segments of the calyx lanceolate-oblong obtuse hispid, barely 1.5 mm. long; corolla rotate 0.5 cm. pedunculate, leaves commonly much shorter, peduncle hispid 0.5-1 cm. long, pedicels  in diameter, 5 lobed to below the middle, lobes ovate-triangular a little obtuse outside glabrous, inside with the margins hairy, incurved, densely ciliate, otherwise glabrous; leaf of the corona with back ascending rising above the anthers, above oblanceolate with inner apex beaked, below oblong with the end cut off, definitely channeled; anthers trapezoidal, appendages hyaline triangular; with the head of the stigma conic.
          Borneo: on trees at Long Dett in the state of Koetei (R. Schlechter #13550, blooming in August 1901).
         A very characteristic species, which has foliage that reminds one of the Aeschynanthus Genus. It is closely related to H. lacunosa Blume.

Compilers Comment: although this species is compared with H. lacunosa Blume which is in the Otostemma Section, this species is in fact in the section Acanthostemma (Bl.) Kloppenburg.
