6. Sansevieriae hyacinthoides group - Leaves flat to semicircular.

    *African to Arabian species

S.aethiopica Thunberg (1794) (S.zeylandica sensu Redoute (1809), S.glauca
Gerome & Labroy (1903), S.thunbergii Mattei  (1918) nom. illegit.,
S.scabrifolia Dinter (1932)) South Africa, Namibia, Botswana, Zimbabwe

S.braunii Engler & Krause (1910) Tanzania, Kenya, Ethiopia

S.conspicua N.E. Brown (1913) Kenya, Tanzania, Zimbabwe

S.dawei Stapf (1902) Uganda

S.elliptica (Chiovenda) Chiovenda ex Guidotti (1932) (S.abyssinica var.
sublaevigata (Chiovenda) Cufodontis (1971), S.forskaoliana sensu Thulin
(1995)) Somalia, Kenya

S.elliptica 'Horwood' (S.'Horwood' Grigsby (1988), S.horwoodii hort.)
(The Frank Horwood collection known as 'FKH 424' is without locality data
but believed to be from Kenya. It was given the cultivar name 'Horwood' by
David Grigsby and appears to be referrable here. Identical plants were
collected 10 km northwest of Kibwezi on the Nairobi-Mombasa road by
Chahinian in 1992.)

S.forskaoliana (Schultes, f.) Hepper & Wood (1983) (S.guineensis var.
angustior Engler (1902), S.abyssinica var. angustior (Engler) Cufodontis
(1971), S.abyssinica N.E. Brown (1913), S.guineensis sensu Schweinfurth
(1894)) Yemen, Sudan, Djibouti, Ethiopia, Somalia, Kenya

S.hyacinthoides (L.) Druce (1914) (S.guineensis (L.) Willdenow (1799),
S.thyrsiflora Thunberg (1794), S.spicata (Cavanilles) Haworth (1812),
S.latifolia Bojer (1837), S.angustifolia Lindberg (1875), S.grandis J.D.
Hooker (1903), S.nobilis Godefroy-Lebeuf (1903) nom. nud., S.grandis var.
zuluensis N.E. Brown, Kew Bulletin 1915 (5): 72, fig. 21 (1915) South
Africa, ?Zimbabwe, ?Zaire (the cultivar known as 'Mason Congo' may be
referrable here)

S.liberica Gerome & Labroy (1903) (S.chinensis Gentil (1907), S.gentilis
Mattei (1918) nom. illegit., S.metallica sensu J.H. Holland (1922))
Liberia, Sierra Leon, Nigeria

S.metallica Gerome & Labroy (1903) (S.guineensis sensu Baker
(1874))?Zimbabwe, South Africa (Natal) cf. Van Jaarsveld, Aloe 31 (1): 13,
fig. 4 (1994) and as S.sp. in Gibson, Wild Flowers of Natal (Coastal
Region) pl. 12 (2) (1975)

S.metallica var. longituba N.E. Brown (1915) (origin unknown) Plant known
as S.'Fumeri-Mozambique' appears to be this plant.

S.metallica var. nyasica N.E. Brown (1915) Malawi
Possibly best included under S.liberica as it agrees with that species in
pedicel articulation.

S.raffillii N.E. Brown (1915) Kenya

S.raffillii var. glauca N.E. Brown (1915) Kenya

S.subspicata Baker (1889) (S.concinna N.E. Brown (1915), S.javanica hort.
not Blume (1827), S.splendens hort., S.nelsonii hort.) Mozambique

As defined here, the leaves of S.subspicata varies widely in length of
petiole, broadness of the blade, color, and degree of maculation.

Van Jaarsveld (1994) included Sansevieria subspicata Baker in the synonymy
of  S.hyacinthoides (L.) Druce. However, in his key to the species, plants
of the former will key out to S.concinna N.E. Brown. The type locality for
S.subspicata Baker "Delagoa Bay" is in Mozambique (former Portuguese East
Africa) not South Africa as listed by Brown (1915). Sansevieria concinna
N.E. Brown is also reported from Mozambique and the two are very similar in
the petiolate, reddish margined, faintly marked leaves. Both species are
reported to be hexaploids by Menzel & Pate (1960), unlike all other
southern African species, including S.hyacinthoides (L.) Druce (syn.
S.thyrsiflora Thunb.), which are reported to be diploid. It thus appears
that the two species are best considered conspecific. It is likely that
plants in cultivation as S.subspicata Baker are descendants of the original
type collection from Mrs. Monteiro made in 1866 and grown at Kew Gardens.

Chahinian (Sansevieria Journ. 1 (1): 7-9, 3 figs. (1992)) has shown that
two collections by John Lavranos that were mistakenly believed to be
collected in Socotra were in fact from Mozambique and represent further
collections of this variable species. Cultivars include: Lavranos & Lubbers
5933 (HBG 28355) 20 km. W of Vilanculos, Mozambique (see Grigsby, Cact. &
Succ. Journ. Amer. 59 (2): 43, fig. 1 (right) (1987)) (as Lavranos 305 (Gl.
& F. 594)); Lavranos 5949 North of Massinga, Mozambique (see Grigsby, Cact.
& Succ. Journ. Amer. 59 (2): 43, fig. 1 (left) (1987) as Lavranos 309 (Gl.
& F. 597))
