and red flowers. It disagrees however conspicuously by the shape ot the 

 labellum vvhicli is said to be lanceolate, while in our plant it is as wide as 

 long and rofundale almost square, (see our F^l. 21, 1. 1, 2). Moreover the bracts 

 of the peduncle have no blades as in the original description, and the 

 measurements of all parts are twice as large. Both species are apparently 

 very near to Z. inflexum Bl. from Java, but there the dimensions are much 

 shorter and the lip and adnate sidelobes are black-purple or violaceous. 



19. Zingiber macroglossum Val. n. sp. 



Herba robusta 2 — 3.5 M. alta, subnutans. Folia magna (ad semime- 

 tralia) sessilia lanceolata basi valde attenuata et canaliculata, apice 

 acute tenuiter acuminata, supra glabra subtus appresse pilosula, ciliata, 

 400 — 500 X 1 10 (in sicco). Ligula maxima 50 — 70 mm. longa 20 — 30 mm. 

 lata, hyalina chartaacea apice subintegra, dorso cum vagina pilosula. 



Spica pedunculata, pedunculo mediocri (200 — 400 mm.) demum pro- 

 cumbente vel arcuato-deflexo ; squamae late oblongae (70 mm. X 20) coria- 

 ceae tomentosae parte superiore imbricantes. Spica ovato-oblonga obtusiuscula 

 (130 X 45). Bracteae densae appressae, oblongae vel late ellipticae, rotundatae, 

 mucrone nullo vel inconspicno, margine latissimo (3 — 4 mm. in sicco), 

 tenuiter tomentosae, margina villosae, infra medium spicae ad 65 X 35 mm. 

 longae. Flores ,,toti albi", ceterum ignoti. ,,Spicarum bracteae griseo-flavae 

 margine rubro-brunneae vel toto rubro-brunneae. Flores toti albi, anthera 

 pallide flava". 



Distribution: Sumatra occ, Sibulangit, in djungle-reservation in 

 humid places, at 300 M. Lörzing 5235. 



Though there are no flowers available for examination, the species is 

 well enough recognizable by the above description. 



The ligula is taller than by any species known (2 — 3 inches) and 

 among those species the ligula has been described of till now, Z. //g'n/ûfz/m, 

 Roxb. differs considerably by the whole habit, lower stature, short peduncle, 

 ligula 20 mm long, etc, though it resembles by the white flowers; Z. intermedium 

 (ligula 40 mm) differs by the acuminate ligula, the blackpurple labellum, 

 etc., Z. squarrosiim Roxb. (ligula 35) by the very different short-peduncled 

 spike, the colour of the flower etc ; and so do Z. roseiim, Rose, Z. clny- 

 sanihum, Rose, Z. rubens Roxb. 



It is apparently nearest to Z. acuminatum Val. Here the peduncles are 

 always procum.bent or creeping, and very varying in length; the bracts are 

 rotundate and without mucro, the flowers white. But here the margo of 

 the bracts is very narrow and the ligula is very short.
