56 THE PLANTS OF MILANJI, NYASA-LAND, 
their slender pedicels, being laxly arranged on the branches of the panicle. It will form,. 
however, as Hackel suggests, a new series comparable with the other seven into which 
Bentham divides the section. This series I propose to call Pectinate. 
PANICUM ($ DIGITARIA) MILANJIANUM, Rendle, sp. n. ; rhizomate tenui, forsan repente ;. 
culmo folioso, subbipedali, glabro, striato; internodiis tribus infimis complanatis, 
superiore terete; vaginis glabris, ore pilosis, striatis; ligula brevi, truncata, brunnea, 
membranacea; lamina late lineari, superne attenuata, nervo prominente, scabrido- 
pilosa; spicis in axe brevi fastigiatis; spiculis in rhacheos triangularis flexuosze late- 
ribus inferioribus paribus alternantibus ordinatis, subcompressis, unifloris ; pedicellis 
parium inzqualibus ; gluma 1™ minima acuta, 2“* profunde incisa segmentis pilosis, 
3" maxima a tergo visa lanceolata, cum duabus carinis, pilosis, 4* florifera late ovata 
apiculata, dorso rotundata, trinervia, glabra, coriacea, palea consimili, sed obtusa, 
inclusa ; antheris brunneis, stigmatibus plumosis. 
The apparently creeping slender rhizome is 13 lines in thickness; the culm is nearly 
2ft.long; the three lower internodes are compressed, the upper one terete above the 
leaf-sheath ; the nodes are brown and glabrous. The leaves are in a radical tuft and 
eauline; the sheaths of the former are 24-3 in. long, of the latter 34, 5, and 9 in. 
respectively from below upwards; the ligule is less than a line long, the broadly linear 
blade tapering above is about 6 in. long by 4-5 lines wide in the middle, with a con- 
spicuous midrib raised above, and numerous less conspicuous lateral veins, scabrido- 
pilose on both surfaces, but especially on the upper. The inflorescence consists of 
15 spikes arranged irregularly on a short axis 2 in. long; the spikes are 6 in. long, 
the spikelets, 13 lines long, are arranged in alternating pairs on the two lower sides 
of the triangular flexuose rhachis; one pedicel of each pair is longer, sharply triangular, 
and closely denticulate like the rhachis, the shorter being terete, with a few small scattered 
teeth. The small acute (not short and rounded as in Digitaria sanguinalis, Scop.) lowest 
glume is } line long; the second, deeply cut into hairy divisions, is 1 line; the third and 
largest, appearing lanceolate from behind, has a prominent, minutely denticulate midrib 
on the flattened back, with two pilose lateral keels, and is 1} lines long; the broadly ovate 
flowering glume, with rounded back and thin transparent margin, encloses the similar 
but blunter and more delicate pale, which is 1 line long. 
Hab. Milanji, Oct. 
Closely allied to Digitaria commutata, Nees, but at once distinguished by the narrow, 
acute, projecting lowest glume, which in D. commutata is equilaterally triangular and less 
projecting. ‘The-leaves are also broader.
