R E I N W A B D T I A Published by Herbarium Bogoriense, Kebun Raya Indonesia Volume 2, Part 3, pp. 373-383 (1954) SUPPLEMENT TO THE GENUS CAREX IN MALAYSIA E. NELMES • SUMMARY This Supplement to the author's monograph '"The genus Cat-ex in Malaysia" enumerates several additional collections. Moreover, a revised description of Carer, ' pycnothyrsos Kukenth. is given, while C. teinogyna Boctt, C- formosensis Lev. & Van. (?), and C. gajonum Nelmes, three species not dealt with in the main work, are fully treated. Part of the important collection of Carices made by Dr. C. G. G. J. van Steenis in Sumatra in 1937 came into my hands too late to be included in "The Genus Carex in Malaysia" (in Reinwardtia 1: 221-450. 1951). With them, from Bogor, were included other Malaysian Carices; some collected by Van Steenis earlier (1934) in Sumatra, others by Endert in Borneo, Buwalda in Java, and Eyma in New Guinea and the Moluccas. While I was considering the question of publishing the determinations of these plants, Dr. van Steenis sent me a request to borrow from Florence, for my work on the Carices of Malaysia, specimens from Erbario Beccari (Sarawak and Sumatra), Erbario Webb (mainly Zollinger type numbers), and others preserved in the Erbario Centrale, especially early Merrill numbers from the Philippines. Incidentally, to help me in identifying these Philippine plants, ten sheets were borrowed from Washington. Some ol the specimens cited are already to be found in the main work and are given here as from additional herbaria. Thus it became clear, with all this hitherto mainly undetermined material, that publication was desirable. In the enumeration which follows B = Bogor, F = Florence, and W = the U.S. National Museum herbarium at Washington. The species are numbered as in the main publication. 1.

Rhizome very short, slender, woody. Stems more or less erect, trigonous, 20—60 cm tall, 0.5—1 mm thick, smooth throughout or angles scaberulous on the upper part of the rhachis, surrounded at the base, below the leaves, by spadiceous sheaths or cataphylls, which ultimately fray into persistent fuscous fibres. Leaves basal and subbasal, rather numerous, shorter to slightly longer than the stems, 1.5—4 mm wide, flat to conduplicate, stiff, green, upper surface thinly covered with pale asperous protuberances, especially above, apices longly attenuated; sheaths dark brown in front and at the concave mouth. Spikes in fascicles of 1—3 at each of about 3—6 nodes, erect or slightly flexuous, androgynaeceous, 0.5—2.5 cm long, lax-flowered, mostly simple but some sometimes bearing 1—few smaller spikes, female part exceeding, usually much exceeding, the male part, upper fascicles subapproximate and overlapping, lower at more widely spaced nodes, upper on scarcely to very shortly-, lower on very shortly to rather longly exserted peduncles; peduncles of each fascicle unequal in length, slender, smooth. Bracts of the lower fascicles subfoliaceous, mostly longer than their fascicles but usually shorter than the whole inflorescence, longly sheathing, upper bracts much reduced, shortly sheathing. Female glumes oblong-lanceolate or slightly obovate- oblong with an acuminate apical part, incurved at the base, otherwise cymbiform, apex acute or sometimes obtuse, 3.5—5 mm long, 1.2—1.8 mm wide, translucent, glabrous, castaneous, sometimes narrowly pale-hyaline on the apical margins, slenderly nervose, muticous or awned, awn up to 1 mm long. Utricles elliptic, plano-convex to compressed-biconvex, 3.5— 4(—4.5), less frequently 5 mm long, 1—1.4 mm broad, membranaceous, slenderly or very slenderly multinerved, not or very narrowly marginate, minutely whitish and subadpressed-hispidulous, straight or straightish, erect to patulous, castaneous, up to about 0.4 (0.5) mm, cuneate-stipitate, subabruptly beaked; beak compressed, slightly tapering, 1.25—2 mm long, more or less subadpressed-hispidulous, bidentate or bidentulate; mouth not oblique; teeth straight. Athene elliptic or oblong-elliptic, subplano- convex or compressed-biconvex, 1.8—2.5 mm long, 1—1.25 mm broad, be- coming dark brown, not stipitate, scarcely to rather shortly beaked. Style-base slightly thickened. Stigmas 2, about 7—10 mm long, curved and flexuous, persistent. 1954] NELMES: Supplement, Carex in Malaysia 379 SUMATRA: A t j e h ; Gajo Lands, foot of Mt.

India, Indo China. I disagreed with Kiikenthal's determination of Backer 13,298 from Java as C. teinogyna Boott (in Bull. Jard. Bot. Buitenz., ser. 3, lfi: 320. 1940) and I thought that Van Steenis 9804 and 9839 from Sumatra, cited with Backer's plant, might also be misidentifications, I therefore excluded the species from nry account of Carex in Malaysia. When, however, the two Van Steenis numbers eventually reached me, I found that my as- sumption was erroneous and that Kukenthal had correctly determined the Sumatran plant as C. teinogyna. 59.

Achene rhomboid, trigonous, faces deeply concave above and below a central horizontal ridge, 1.75—2 mm long, about l m m broad, curved-tapering below to a scarcely or shortly stipitate base, gradually tapering above to a slightly constricted apex and then slightly expanded into a scarcely cylindric neck but rather discoid-annulate apex, 0.3—0.4 mm in diameter. Style slender, its scarcely thickened base centred in the slightly hollow apex of the achene. Stigmas 3. P H I L I P P I N E I S L A N D S : L u z o n ; Benguet, June 1911, Merrill Phil. PL SOS (F, W) ! Korea, Japan, Formosa. I have not seen the type of C. formosensis and the species is not represented in the herbarium at Kew. Merrill's number 562 does not altogether agree with the descriptions of it, but there does not seem sufficient variation to warrant the proposal of a second species. At present, therefore, there is some doubt as to whether C. formosensis be- longs to the Malaysian flora. 64. CAEEX BREVISCAPA C. B.

CAREX GAJONUM Nelmes Carex gajonum Nelmes in Kew Bull. 1952: 84. 1952. — Sumatra, van Stcenis 8591. Tufted. Stems erect, obtusely trigonous, smooth, scaberulous at the apex, just below the inflorescence, 20—90 cm tall, 1—2 mm thick below, ribbed and striate. Leaves few, subbasal, shorter to longer than the stems, 1.25—2.5 mm wide, flattish-eanalicu'ate, margins often recurved, apices longly attenuated, lower leaves reduced to bladeless or nearly bladeless sheaths. Spikes 5—8, gynaecandrous, but male flowers so few that spikes appear wholly female, ellipsoid in flower, obovoid or oblanceoloid in fruit, 5—10 mm long, 3—5 mm thick in fruit, dense-flowered, suberect to patulous, sessile, all crowded or approximate, or, sometimes, lowest at a node up to 14 mm from that next above, forming a terminal, slenderly or more stoutly oblong or, less commonly, ovoid head, 1.5—4.25 cm long and 4—Sum thick. Brads of the lowest 1, less commonly 2, spike(s) setaceous to subfoliaceous, remaining spikes ebracteate or bracts repre- sented by large and longly awned glumes. Female glumes ovate or ovate- lanceolate, cymbiform, base incurved, apex acute, 3 mm long, 2 mm wide, translucent, very slenderly plurinerved and bright eastaneous, nerveless on the thinner, wide, whitish-hyaline margins, midrib and 2 adjacent nerves which coalesce with it above more or less extending to the acute whitish-hyaline apex. Utricles broadly ovate, or sometimes suborbicular, excluding the beak, plano-convex, or concavo-convex owing to spongy- thickened margins and base which are slightly ventrally incurved, 3.25— 3.5 mm long, about 2 mm broad, slenderly but distinctly 8—12-nerved 373 374 375 376 377 378 379 380 381 382
