Brunsvigia

Mary Sue,
Thanks for pointing out the tumbleweed inflorescence difference. Perhaps
this correlates with the rounded seeds of Brunsvigia, versus the slightly
compressed-angled seeds of Amaryllis.

From "Cape Plants" (Goldblatt & Manning 2000) these characters are used to
separate Amaryllis from both Nerine and Brunsvigia:

1 Leaves with a prominent midrib; perianth longer than 8cm; seeds slightly
angled by compression, pink to colourless, only embryo green.... Amaryllis

1' Leaves without a midrib; flowers shorter than 8cm; seeds ovoid, usually
reddish, integument and embryo green.... Brunsvigia, Nerine, Crossyne

It is more fun to think about the relationships of plants than to think
about the consequences of rearranging their nomenclature!

Hi,

Not all Brunsvigia leaves look alike. If you look on the wiki you'll see
some of the variety. In the Color Encyclopedia they are described as:
"Leaves 2-20 but mostly 4-6, green or dry at flowering, suberect or
pressed
to the ground, oblong to tongue-shaped, the upper surface smooth to
papillate or bristly, the margins usually raised, often minutely fringed."
But I guess the difference Dylan is talking about is the midrib which only
Amaryllis has making it different from the other genera in this family in
South Africa. The Brunsvigia leaves are much more broad than Nerine
leaves.

I agree that some of the Brunsvigia flowers remind me of a large Nerine,
but others have such a widely spreading umbel with flowers on the end of a
long pedicel and don't look at all like Amaryllis belladonna or Nerine.
The
length of the pedicel is also significant in the key as the Amaryllis
flowers are usually much longer than the pedicels. A lot of the
Brunsvigia
species after they bloom become a tumble weed distributing seeds as they
go
which is also very different from Amaryllis.

Jim (Waddick) can look at some of the pictures of B. orientalis on the
wiki. Mine has never bloomed. They look a lot like the picture he
referenced of the hybrid.

And if you really want to get into a discussion of lumping what do member
of this group think about putting Amaryllidaceae back into Alliaceae as
proposed?
