Wilson and Johnson, Juncus (Juncaceae) in Malesia 
379 
(mis-cited by Ridley as '3745') is ]. inflexus. Clemens 30421 is a poor and not readily 
assigned collection. It has the long (3.5 mm), more strongly red-brown tepals and red- 
brown capsules of subsp. sundaicus but lacks bases to check the cataphylls. We have 
not seen this last collection side by side with the supposed original voucher for these 
cultivated plants (see below) so we cannot at this time resolve the question of whether 
this Clemens collection is indeed this subspecies, cultivated in Java, or is instead subsp. 
medianus, which is native in Java. 
The fourth collection ( van Steenis, Papandayan, Java) was not seen in K but apparently 
equates to Van Steenis 12331 (J.F. Veldkamp, pers. comm.), which we have seen in L and 
which is also referable to subsp. medianus. That collection from Mt Papandayan was 
cultivated at Mt Gedeh, which plants in turn were the source of Clemens 30421 
according to the annotation on the latter sheet by Van Steenis. He did not indicate the 
number of his original Papandayan specimen, but J.F. Veldkamp (pers. comm.) 
confirms that the specimen cited by Ridley, Van Steenis 12331, and the source of the 
cultivated plants are one and the same collection. 
As noted in the key to subspecies, this subspecies differs from the others in having 
longer tepals that consistently have dark red-brown bands of colour beside the midrib 
(bands only occasionally present, a very dark red-brown capsule and cataphylls that 
are usually red-brown for most of their length.

6. *Juncus inflexus L. 
(Linnaeus 1753: 326) 
Type citation: 'southern Europe'. 
Shortly rhizomatous perennial. Culms terete, more or less soft, blue-green to grey- 
green, glaucous, 25-70[-120] cm long, 1.0-1.5(-2.0) mm diam.; striations [10—]17—22; 
pith regularly interrupted, moderately dense, rarely continuous. Sterile leaf-like culms 
present but real leaves reduced to cataphylls 6-10 cm long, more or less loose around 
culms, abaxially pale brown at apex to very dark red-brown or blackish at base, 
adaxially pale straw-coloured above to dark golden brown towards base. Inflorescence 
3-9 cm long, diffuse, with numerous solitary flowers; lowest involucral bract 12-20 cm 
long, apparently continuous with culm, exceeding inflorescence. Flowers with 2 
bracteoles. Tepals acuminate, straw-brown, often with red-brown bands each side of 
midrib, usually with narrow (less than 0.2 mm wide) hyaline margins; outer tepals 
[2.5-J3.0-4.0 mm long, exceeding inner tepals. Stamens 6, shorter than outer tepals; 
anthers 0.7-1.2 mm long, generally greater than or equalling filament length. Capsule 
3-locular, slightly shorter than to slightly exceeding outer tepals, elliptic to narrow- 
ovate, dark red-brown to blackish, acute, shortly beaked (c. 0.3 mm long). Seeds 
0.4-0.6 mm long.
