Convolvulus
retrosepalus
Sa'ad
, Meded. Bot. Mus. Herb. Rijks Univ. Utrecht 281: 69. 1967. (
Sa'ad
1967
: 69).
Type.
AFGHANISTAN,
Lindberg
317 (holotype W!).
Distinguishing features.
This differs from
var. leiocalycinus
by the narrowly lanceolate, reflexed sepals, c. 7
x
1 mm, the veins usually conspicuous. The leaves and ovary are glabrous.
Distribution.
Restricted to Afghanistan, Farah Province (
Hedge & Ekberg
7252,
Hedge et al.
7739,
Grey-Wilson & Hewer
557,
Carter
824).
Note.
Intermediates with
var. leiocalycinus
occur quite frequently (
Grey-Wilson & Hewer
534,
Podlech
21729,
Rechinger
33380,
Koie
4414). These are similar to
var. retrosepalus
in their lack of hairs but the sepals are obovate and spreading.
