Oxalis obtusa
is common and widespread and found on sandy or clay soils
from
Namaqualand
to Knysna. This species mostly grows to 10 cm and has hairy
or hairless leaves of three. Leaves are different shapes and sizes.
Flowers are solitary and come in many colors: pink, shades of peach
to apricot and orange, brick red, yellow, white, multicolored. Many
of the colors and forms are pictured below. The first photo shows
scanned flowers of the different colors and the second is a
composite of individual pictures of
Oxalis obtusa
in Ron Vanderhoff's collection.
OB系列酢浆草，常见且传播较广，生长于
Namaqualand至Knysna的沙地或者粘土中。这个系列大部分10公分高度，叶片为毛茸茸或者光滑的三叶。叶片形状尺寸各异。花朵不多且颜色各异（？）：粉色，杏色，橘色，砖红色，黄色，白色以及混色。大部分图片如下图所示。所边的图示不同花色，右边是
Ron Vanderhoff收集的品种开花图片。
As is the case with many other
Oxalis
species, there is a great deal of variation not only in
flower colour, but also in leaf shape, of specimens of
Oxalis obtusa. Normally such
differences would be small within a population and more marked
between populations, but the first two pictures show differences in
flower colour and leaf size of plants in Grootvleipas (
Namaqualand).
The third photo is of a yellow form of
O. obtusa
from Springbok. The bulbs are still immature, and the leaves
show different stages of development. Note the prescence of the
short broad immature leaves and the longer slender adult ones on
the same plant (bottom right). Photos by

与其他酢浆草种类一样，OB系列酢浆草无论在花色上，还是在叶子形状上，都有巨大差别。通常来说，同一种类之间差异不大，不同种类之间可能明显些，但是如下面前两张图片显示，同是在Grootvleipas
(
Namaqualand)生长，花色和叶子大小差异明显。第三张图片是来自Springbok的OB
yellow。
种球还在孕育中，叶子展示了生长发育的不同阶段。短而宽的未长成的叶子和细长的长成的叶子共同生长（如下右图）。
In the Little Karoo in South Africa in September 2003 a large patch
was seen in bloom making the area look apricot-orange from a
distance. From a distance they all looked the same color but up
close there were many variations. Here are two. Photos by

Rutemoeller.
2003年9月份，南非little
karoo地区，开花的酢浆草点缀着土地，从远处看一大片都是橙杏色；但是走近了看，发现有许多品种。这是由Bob
Rutemoeller拍摄的数张照片。
There were many variations in colors seen in populations
photographed near Middelpos in the
Roggeveld
September 2006 by
Mary
Sue Ittner. Ones growing under shrubs where they had some
protection seemed more vibrant. The last picture shows them in mass
blooming along with other spring flowers.
2006年9月，mary sue ittner 在roggeveld
middelpos拍摄的照片显示，种类间的花色差异很多；灌木下受到些许保护的更有活力。最后一张图片显示的是与其他春季花朵一起开房的酢浆草。
