48) Pterocaryoxylon pilinyense GREGUSS, 1969 Pl. 2, Fig. 13

M a t e r i a l. Holotype HNHM-PBO 2008.222 .3. (= 3 slides: tr + tg + rd).

D e s c r i p t i o n. See Greguss (1969: 77, pl. LXXI, figs

1–9, legend p. 147).

N o t e s. The vessels are solitary or in multiples of 3 or more with dense intervessel pitting, axial parenchyma is present as banded, in 1–3-cell wide tangential bands, and paratracheal vasicentric. Crystals are in chambered axial parenchyma, clearly seen in the radial section, with about 8 chambers per strand (Pl. 2, Fig. 13). This type is known today as Rhysocaryoxylon pilinyense ( GREGUSS, 1969) DUPÉRON, 1988 (see in Sakala and Gryc 2011).
