Cryptocoryne longicauda Engler

Cryptocoryne longicauda ("with the long tail") was collected by Odoardo Beccari in Sarawak and described by Engler in 1879. One year later, in 1880, N.E.Brown described C. caudata from Sarawak with deep bullate leaves and much later, 1920, Engler described C. johorensis from Johore (W.Malaysia) which are all regarded now to be synonyms of this species (Jacobsen 1982, 1985). Beccari only made a poor drawing of the inflorescence of C. longicauda, so the confusion is understandable. Around 1970 this species was also collected from Sumatra, so the distribution of this species is quite broad.
To make things completely crazy, around 1950 a new plant form Borneo was imported which resembled C. longicauda. In the Dutch and German literature until 1970 a couple of articles appeared on this species. This plant proved to be C. fusca (Bastmeijer & Bouwmeester 1990).

For irrigation, the ditch is cleaned and hundreds of  plants are drying out on the bank.

In cultivation the leaves are slight bullate. Adult plants show a fine undulated margin of the leave.

A closer look at the leave margin. The tissue is membranous thin.This is only seen in C. longicauda.

About one day after the spathe opens, the limb may bent down.

Mostly the limb of the spathe forms a perfect half sphere. There is a pronounced collar.

Sometimes the limb opens more widely. The colour of the limb is mostly dark red, but as seen here rather bright. From Sumatra (Djambi).

Cryptocoryne longicauda is quite easy to cultivate emerged under standard conditions. Submersed the cultivation of this species is rather difficult on the long term.
The inflorescence is rather unique. Only the tail reaches up to 20 cm! Plants with the deep bullate leaves as seen in the type material for C. caudata are never seen again. Perhaps it is a local form, variations of this kind are also seen in C. minima.
Cultivated plants of C. longicauda are rather common in the Western Europe.
