in. long, contiguous or shortly separated. Male flowers with brownish 
linear-spathulate or cuneate-spathulate, entire or variously lobed or 
toothed, acute bracteoles; pollen simple. Female flowers usually 
ebracteolate, occasionally with a few narrow spathulate-lanceolate 
colourless bracteoles mingled with them; stigmas spathulate-lanceo- 
late, longer than the simple hairs.—Kronfeld in Verhandl. Zool.-Bot.

This may be distinguished from 7’. latifolia, Linn., by the bracteoles of the male 
inflorescence being brownish and_usually more or less lobed or forked at the top, and 
by the simple pollen. A specimen without flower, collected by pools near the sea, 
and near San Pedro, in the district of Loanda ,Angola (Welwitsch, 242), is doubtfully 
referred to this species by Rendle in Cat. Afr. Pl. Welw. ii. 85. Kronfeld and 
Graebner have erroneously referred 7. equinoctialis, Welw. to T. australis, Schum. 
& Thonn., from which the absence of bracts to the female flowers at once distin- 
guishes it. 
OrveR CL. AROIDEA. (By N. E. Brown.) 
Flowers unisexual or hermaphrodite, with or without a perianth, 
sessile on a spadix enclosed within, adnate to, or subtended by a green 
or coloured spathe. Spadix monecious or entirely covered with her- 
maphrodite flowers, or rarely unisexual, with or without a terminal 
barren appendix, and with or without neuter organs on various parts 
of it. Perianth, when present, of 3-9 free or connate segments. 
Stamens 4—6, rarely more or fewer (when the male flowers’ have no 
perianth, the stamens are crowded together, so that the number belong- 
ing to each flower is often indeterminable), free or connate ; filaments 
none, or broad and flat, or rarely filiform or clavate ; anthers opening 
by terminal pores, or by short or long longitudinal slits ; pollen often 
emitted in sausage-like strings. Ovary sometimes surrounded by 
staminodes, superior, or very rarely inferior, with or without a style ; 
1- to many-celled, with axile, parietal, basal or apical placentation ; 
stigma entire or lobed ; ovules 1 to many in a cell, orthotropous, campy- 
lotropous or anatropous. Fruit a 1 to many-seeded berry. Seeds 
albuminous or exalbuminous.—Erect, creeping or climbing herbs or 
shrubs, simple or branched. Rootstock often tuberous or thick and fleshy.
