rows on each side, forming a superiorly rounded area, and they are not adcurrent to the costa. The costa is frequently (but not always!) spinose-hispid on both sides, propaguliferous toward the apex (eventually also below it), terminating abruptly before the mucronate apex. The laminál cells are papillate, the papillae are situated singly and centrally on the cells, protruding at different rates, occasionally strongly reduced or absent : var. n. epapillosa (diagn. : a typo differt cellulis epapülosi pellucidis). It is a most important feature that the papillae, if they are present, are always simple, monoapical. On the backside of the lamina, two zones of mamilliform bristles, instead of papillae, ornament the cells. On the border of the leaf base and the lamina (the shoulder of the leaf), there are 30—80 u. long spiniform cilia, generally erect or eventually inclinate. The leaf margin is otherwise whole, bordered by elongate cells (exohyalocysts) to about three-fourth of the laminál length (cf. Fig. 1). Syrrhopodon larminati PAR. & BROTH, is an indubitable ally of the nominate species of the Section, Syrrhopodon cavifolius LAC, inhabiting the islands Borneo and Banca. However, the leaf base of S. cavifolius is broad, the cancellinae are arranged into about 10—10 row

T

s, and the shoulder bears not true cilia but merely short teeth. We have also examined the African species relegated to the Section Cavifolii, namely S. armatus MITT., S. afrociliatus G. MÜLL., S. rubrotomentosus CARD., because we could not preclude the identity of any one of them with S. larminati. (cf. Fig. 2). However, all African ciliferous Cavifolii species differ from Syrrhopodon larminati by their relatively narrower leaf base, in which the cancellinae are arranged in merely 2 — 4 rows, and are also far adcurrent to the costa. Also, the papillae of S. armatus are frequently multifid ; S. afrociliatus has more slender and fragile stature, with narrower and flatter leaves. It is Syrrhopodon rubrotomentosus CARD., which seems to stand nearest to Syrrhopodon larminati PAR. & BROTH., but the arrangement of the hyaline cells also separates it specifically (cf. Fig. 3). Of the South American species, Syrrhopodon leprieurii MONT, and Syrhopodon brevisetus FLORSCH. have leaves spinosociliate at the shoulders, but the leaf form of S. leprieurii is quite different, and the cells of S. brevisetus have multifid papillae.

Accordingly, of the Asiatic ciliferous Syrrhopodon species, S. larminati has the northernmost range. It is a South-East Indian, Far East species, of a subtropiccharacter. Specimens indicated by an asterisk had been examined by the authors.
