AFBIDIA Duthie in Journ. Bomb. Nat. Eist. Soc. xi. 696 (1898).
Natural order Labiatse.
Calyx tubular, 15-nerved, slightly curved, mouth oblique, entire; coroZii-tube
slender towards the base, exaerted, without a ring of hairs within; limb 2-lipped,
posterior erect, concave, bifid; lower spreading, 3-fid; mid-lobe larger than the lateral
ones, bifid; stamens 4, nearly equal, ascending beneath the posterior lip, exserted or
included; anthers 2-eelled, lobes diverging and at length divaricate; disk divided into
four equal lobes; style included or exserted, bifid; lobes subulate, nearly equal;
nutlets obovoid, minutely tuberculate, with a V-shaped areole at the base.—Suffruticose,
with many branching stems; flowers in densely packed verticillasters formiug
compact tei-minal spikes, or with the lower clusters more or less interrupted; corolla
pale-yellow tinged with lilac.
This gonus is most nearly related to Nej>eta, both as to its habit and in its
general structure; but the truncate mouth of the calyx distinguishes it from all
other genera of the tribe Nfpetecs. The dimorphism of the flowers might suggest an
affinity with Osynepcta of Bunge (^a section of Nepeta), but the tendency in Afridia
is towards a dioecious condition.

tapering gradually in the posterior halt to a petiole 1—2 cm. long, margins entii-e,
nerves 12—14 pairs slightly arched forward, minutely puberulous on botli surfaeee,
attaining 20 cm. long by 8 cm. wide, broadest at junction of anterior and middle third;

Very closely related to Gymnostachyum latifolium T. And. and, along with that
species, standing markedly apart from the other Indian species of Gymnostachyvm. Jt
is, however, veiy distinct from G. latifolium in the different folliage, the smaller
flowers with different anthers, and the smaller capsules.
