We drove to Hazel Ridge hoping to find Rhoicissus
digitata in flower. Richard Boon had asked if we could
keep an eye open for it. Photographs of this plant in flower
had only been documented once on I-Naturalist. Gail found it growing on the forest
edge between rocks, but, as usual, no flowers were seen. However, Dorothy
managed to capture Rhoicissus tridentata in flower in
the grassland.

We explored the grasslands briefly before going to the
forest edge and observed three flowers which looked similar to each other, that
being Pentanisia angustifolia, Wahlenbergia
huttonii and Buchnera dura.
The Pentansisa was going over and one could be confused as to
what one was looking at and this is why it is so important to look at the leaves
and stem to differentiate between the species for correct identification.
Along the forest edge, we found Osteospermum
moniliferum flowering abundantly. Yellow is certainly the
most uplifting colour. Our rare and endemic Crassula sarmentosa var. integrifolia flowered,
and Carissa wyliei had fruits. Tricalysia
capensis var. capensis was both flowering and
fruiting.

Maggie kept a close eye on Gail as she had ventured very near the edge of The Shoot looking to see what was growing on the steep shaded slopes. Gail spotted a baboon trail and decided to follow it with Anne and Alf following behind. There, they discovered Streptocarpus formosus, Streptocarpus haygarthii and Streptocarpus polyanthus polyanthus. An embankment stretching as far as the eye could see was full of Streptocarpus formosus. It was the most beautiful sight—we had never seen so many plants and in flower. It will remain in our memories for a life-time.
Streptocarpus formosus, commonly known as the Pondo Streptocarpus, is a captivating plant native to the sandstone gorges of Umtamvuna, Oribi, and Port St. Johns. The name formosus translates to "beautiful," a fitting description for its long, soft, mauve trumpet-shaped flowers. The plant’s leaves are covered with fine white hairs, and their undersides are a pale green.
This species thrives in well-drained soil, often growing between rocks in tropical forests where summers are humid and wet. Streptocarpus formosus is easily cross-pollinate with other species, but it’s also capable of self-pollination. Within a month or two, it releases thousands of fine brown seeds from two long fruits. When dried, these fruits spiral open—a process that inspired the plant’s name. Streptocarpus comes from the Greek words streptos (twisted) and carpus (fruit).
One of the most fascinating features of Streptocarpus formosus is that each leaf acts as an independent plant, complete with its own roots and flowering stems. As the plant ages or faces environmental stress, the tips of its leaves may die off. However, this doesn't harm the plant; instead, the leaf forms an abscission layer, and fresh growth continues from the base. This survival strategy allows the plant to adapt to drought or cooler temperatures. Propagation is straight forward—Streptocarpus formosus can be grown from a single leaf.

Sansevieria hyacinthoides has striking red margins, it thrives in rocky
woodlands under the shelter of trees. Its sweetly scented, cream-colored
flowers are fragrant, attracting moths for pollination. Birds love the
vibrant orange berries. These plants are known for their air-purifying
qualities and makes excellent indoor plants. The rhizomes and leaves have
been used medicinally to treat a range of ailments, including ear infections,
toothaches, and earaches, ulcers, worms, stomach disorders, and haemorrhoids. |
