There are a few well-grown specimens of valonea oak (Quercus Ægilops) to be seen, but being a slow grower and as it takes many years to reach the stage when it yields a profit, it does not commend itself to the Cypriot tree planter. It prefers deep soil and requires artificial irrigation or a greater rainfall than we have in Cyprus.
It has been tried at Salamis and failed, and also at Machaera with the same result. It has been grown also on Troödos, but after six years' growth attained a height of only 1 foot.
Only an insignificant quantity of Valonea cups are locally produced. These come from the Paphos district and are said to be rather poor in tannin. The bulk comes from Anatolia. The pre-war price for the latter was 5s. per cantar of 44 okes, that for the locally grown was 20 paras per oke on the spot, transport charges bringing up the price to about 1 copper piastre per oke delivered.
Acacia Barks
Acacia pycnantha has been grown in Cyprus, but does not acclimatise well, and neither the soil nor climate seems favourable. A. mollissima also has not shown any very successful growth. A. cyanophylla and A. longifolia, on the other hand, thrive excellently. They are great drought-resisters and grow on almost any soil. They have been very extensively grown by the Forest Department in every district for fuel and along the coast upon sand dunes. They have not been utilised so far for the extraction of tanning, except experimentally. Samples of the barks of the two last-named species were found on examination at the Imperial Institute to be too poor in tannin to be worth exporting, but they should be quite suitable for use in Cyprus (see Bulletin of the Imperial Institute, vol. xi. 1913, pp. 412-414).
Madder
In former years, and within the period of the British occupation, the cultivation of madder (Rubia tinctorum) was fairly flourishing in Cyprus. The old madder grounds can still be distinguished, and are mostly to be seen near Morphou, Ayia Irini, Sotira, Ayios Serghios, Famagusta and Larnaca. These madder grounds were excavations made in order to expose the soil lying beneath 10 to 30 ft. of drift-sand; and they form, as it were, a series of tanks along the shore. The red dye obtained from the dried and ground madder roots constituted at one time one of the most valued of dye-stuffs, and was in special demand for military uniforms; but this has been entirely superseded by artificial coal-tar derivatives and, as Gennadius says: "The happy days of the cultivation of this plant are past, never to return."
It is propagated mostly by root cuttings. The leaf begins to dry at about the sixth month. There is no further growth above ground, but the roots continue to increase and shoot downwards till moisture affects them. "When they get too wet, they become black or rot. In Cyprus this rotting would often begin after about eighteen months, while in superior soils the roots would continue to improve during thirty-six months, and they would be known in the trade as eighteen months and thirty-six months roots. In Famagusta district they remain mostly eighteen months, while at Morphou they would continue fully thirty-six months, during the whole of which time the surface ground should be kept free of weeds."
After the root is lifted it is generally dried; if packed before quite dry, it ferments and deteriorates.
Two and a half tons of dried roots would be produced from an acre of good ground, and the madder grounds used to fetch a very high price.
