Type: Indonesia: Sumatra: Korinchi Peak [now Mt Kerinci], 7300 ft [2225 m], H.C. 
Robinson and C.B. Kloss, 25 May 1914; holo K; iso BM. The K sheet is a duplicate 
distributed from BM, and there are two minor differences in label information that 
probably result from transcription errors between the original and duplicate: the BM 
sheet bears a collectors' number '82' and the month of collection is given as April. 
However, all other details tally and the material appears to have come from the same 
collection, so it is assumed that the BM sheet is indeed an isotype. 
Culms 20-50 cm long, 1.0-2.0 mm diam.; striations c. 20-30. Cataphylls 5-10 cm long, 
abaxially more or less evenly red-brown to dark red-brown. Inflorescence 2-4 cm long; 
lowest involucral bract 7-15 cm long. Tepals acuminate, straw-coloured centrally with 
a broad darker red-brown band each side of midrib, and with broad to more or less 
narrow hyaline to whitish margins; outer tepals 3.0-4.0(-4.5?) mm long. Anthers c. 0.5 mm 
long, shorter than filament length. Capsule slightly shorter than to equalling outer tepals, 
obovoid to narrow-ellipsoid, very dark red-brown, scarcely beaked. Seeds c. 0.6 mm long. 
Illustrations: Backer (1951: fig. 2b), as J. effusus. 
Distribution: Endemic to Malesia: probably only on the island of Sumatra (Aceh 
Province). Ridley cited four collections from Java, three of which we consider to be 
referable to subsp. medianus or to /. inflexus, while the fourth is an incomplete 
cultivated specimen from West Java ( Clemens 30421) — see below. 
Notes: Ridley (1935) clearly designated the type specimen, which is a good example of 
this taxon. However, he had a mixed concept of the taxon, as indicated by the range of 
collections cited in the protologue. Of the other four collections cited by him, all from 
Java, three have been seen on loan from K. Of these, Koorders 26505 (mis-cited by 
Ridley as '26550B') is referable to J. decipiens subsp. medianus and Koorders 37457
