From its description, /. yakcisidakcnsis Satake is probably a synonym of J. leschenaultii. 
Ohwi (1965: 277) accepted/, yakcisidakcnsis (as 'yakeishidakensis'). We have not seen the 
type, but we have seen other collections determined as this species by Satake himself, 
and they are referable to J. leschenaultii. 
Most of the collections from the Philippines (e.g. Merrill 4517, Ramos and Edaho BS 
40417, and Mearns BS 4261) are very slender and weak, looking like they might have 
been growing in water. They superficially resemble rather coarse plants of J. sandivithii 
but differ in being proliferous, having pluritubulose leaves (so far as seen in the 
slender leaves) and in having a much less angled and shorter, broader capsule. The 
septa are hard to see in the slender leaves and the compressed state is not obvious (in 
fact, they are terete at the apex), but the presence of longitudinal striations as well as 
the transverse septa is indicated externally by the more striate appearance of the 
leaves (at least when dry). In general, the leaves of /. wallichianus have a much 
smoother (less striate) appearance than in J, leschenaultii and /. prismatocarpus. 
Duistermaat (manuscript at Leiden; Veldkamp pers. comm.) planned to recognise the 
slender material as a variety (var. luzoniensis [sic] ined.) but that has never been 
published. In our view this is not justified since the slender Philippines collections are 
similar to other material of J. leschenaultii (see, for example, Li et al. 1243 from China) 
and seem to be no more than a montane form of that taxon, and merely show 
convergent resemblance to /. sandivithii.
