ACANTHACEX (S. Moore) 19 
apice truncatis vel emarginatis ipso mucronatis apicem versus 
margine spinuloso-denticulatis vel integris papyraceis glabris; 
bracteolis lineari-lanceolatis acuminatis calyce brevioribus ; calycis 
segmentis inter se subaequalibus lineari-lanceolatis acuminatis 
integris anticis vero (an semper?) sparsissime spinuloso-denticulatis 
omnibus nervo unico percursis ; corollae tubo ex bracteis eminente 
faucibus levissime ampliato lobis tubo multo brevioribus inter se 
subsimilibus oblongo-ovatis obtusis; staminibus faucibus affixis 
antheris apice mucronulatis; pollinis granis subsphaeroideis 
subtilissime punctatis ; ovario ellipsoideo glabro. 
Oban ; n. 1026. 
Leaves 7-10 x 8:0—4:5 cm., drying brown-green above and 
greyish below ; petioles 1 to nearly 3 em. long, stout, covered with the 
same pale fulvous tomentum as the stem. Spikes 5-9 cm. long, 
about 1:5 em. broad, the lowest bracts generally entire, 10-13 mm. 
long, the upper ones 20 mm. long, 7 mm. broad, all traversed by 
several rather prominent longitudinal nerves, with transverse con- 
necting nervules. Bracteoles 6 mm. long, like the calyx subscarious 
and glabrous. Segments of calyx 9 mm. long, 1 mm. broad about 
half way up; midrib prominent, especially at the base, each with 
several closely packed longitudinal nerves on either side of the 
midrib. Tube of corolla 18 mm. long, nearly 2 mm. wide at the 
throat, elsewhere 1 mm. ; lobes about 11:0 x 4:5 mm. Filaments 
rather more than 1 mm. long, bearded above. Anthers slightly 
curved, 2 lines long. Ovary 2:5 mm. long. Style thickened towards 
. the apex, slightly hairy, 2 em. long. Stigma 2-lobed, rather more 
than 1 mm. in length. 
Readily known from C. puberula Klotzsch and C. guineensis 
Nees by the truneate braets and the calyx. The spheroidal pollen 
is abnormal, though it should not be forgotten that two quite different 
kinds of pollen are found in the neighbouring genus Stenandrium. 
Apparently referable to the above, and differing from it only in 
the larger and longer-stalked leaves and the larger bracts, are specimens 
of Bates, nn. 490 and 546 from Batanga. At Kew the specimens 
have affixed to them a MS. name of Pierre, who considered them to 
belong to a new genus.
