Euchaetis albertiniana

  1. Euchaetis albertiniana Williams in J1 S. Afr. Bot. 41 (3): 167 (1975). Type:
    CAPE 3421-(Riversdale): Near Askop on south side of road 16 km west of
    Albertinia (-AB), 180 m alt., 2/3/1974, Williams 1879 (NBG, holotype; K, PRE,
    STE, isotypes).

Euchaetis albertiniana is recognised as distinct from E. burchellii Dümmer in
that it is destroyed by fires whereas E. burchellii develops a stout rootstock from
which it may regenerate after fires - a character seldom noted on herbarium
sheets. However, the leaves in E. albertiniana are often adpressed, ciliolate with
an apical callus, whereas those of E. burchellii are never so. The anther in E.
albertiniana possesses a small pointed gland, but that of E. burchelli is minute
E. albertiniana differs frọm E. laevigata Turcz. which has leaves complicate
orbicular, spreading and somewhat more recurved towards the apex with the
apical gland on the anther minute as in E. burchelli, E. albertiniana is found in
the vicinity of Albertinia. E. burchelli is more widespread being found in sandy
soil from beyond Great Brak River in the east to Uilenkraal River near Gans
baai in the west.

Euchaetis burchellii

  1. Euchaetis burchellii Dümmer in Kew Bull.: 90 (1912)
    Type: CAPE--3422 (Mossel Bay): sandy hills near the landing place, Mossel
    Bay (on shrubby sandy dry hills close to our station near landing place Mossel Bay), 18/10/1814, Burchell 6239 (K, holotype).

Shrubs to 1 m tall forming a dense bush with many stems arising from a stout rootstock. Branches short, fairly erect, bark scaly and rough. Branchlets numerous, slender, very short, puberulous, well-clothed with leaves. Leaves to 4,5 mm long, 1,5 mm broad, lanceolate, obtuse without any mucro, sub-trigonal, glabrous, eciliate, sessile, opposite, erect, sub-imbricate, decussate, about twice times longer than the internodes. Inflorescence terminal, usually twin, white or pink. Bract one to each flower, 1,9 mm long, 1,3 mm broad, ovate, obtuse, glabrous, thickened toward the apex, sessile, very sparsely ciliate, midrib 1-2 gland-dotted. Bracteoles two, 1,6mm long, 0,8 mm broad, elliptic, obtuse, glabrous, apex thickened; margins broadly translucent, ciliolate. Calyx lobes five, 2mm long, 1,5-2 mm broad, roughly orbicular, glabrous; apex blunt, trigonal, green; margins broadly translucent, ciliolate. Petals 3.7- 4 mm long, 2,5 mm broad; limb orbicular, 1-2 gland-dotted; claw transversely bearded, midrib pubescent, margins ciliate. Staminodes vestigial, 0,15 mm long, 0,1 mm diam. Filaments 5, 1,3 mm long, pale, acicular. Anthers five, 0,6 mm long, wine-coloured; apical gland minute. Pollen 52 micron long, 32 micron broad, ellipsoid with three longitudinal grooves. Disc closes over the ovary at first. Stigma 0,5 mm diam., globose, capitate. Style becoming 1,5 mm long, erect, persisting. Ovary 5-carpellate, 0,7 mm diam., with a few hairs at the sides towards the apex of each segment. Fruit 5-carpellate, 6 mm long overall, glabrous, gland-dotted; horns 1,2 mm long, clasping a gland at the tip. Seed 4,2 – 4,8 mm long, 1,8-2 mm broad, black, shining; aril white.

Euchaetis burchellii is a lowland coastal species found growing in stabilised
wind-blown sand never very far from the sea, at altitudes of from 33 to 250
metres above sea level. Its geographical range extends from Herolds Bay near
George in the east to the Uilenkraals River near Gansbaai in the west, a dis-
tance of about 275 km.

It is a dense shrub with many stems arising from a stout rootstock, having
leaves lanceolate, obtuse, eciliate, without any apical callus and never adpressed.

It is perhaps closest to E. albertiniana Williams which however is a fairly
diffuse shrub, single-stemmed at base with leaves sometimes adpressed and with
a small apical callus. It differs from E. laevigata Turcz. which has leaves sub-
complicate, orbicular and spreading and is found growing upon limestone to the
east of Bredasdorp

Notes re Crassula rupestris: Mini Maxi and Jelly Bean

Recorded at Matjiesvlei, also at Gamkaberg Nature Reserve:

  1. A bigger a smaller version of classic C rupestris. They co-occur, although there could be a slight difference in preference when it comes to elevation. Both in image, first link above.
    2.Another plant is Crassula cf rupestris ‘Jelly Bean’. It also co-occurs with Mini and Maxi. It does not seem to fit into any of the three known subspecies of C. rupestris.

There was a bit of vindication for me when I discussed this with Louis Jordaan of Minwater. He has also noted Mini and Maxi and even had a photograph of a Jelly Bean on his tablet to show (GCBR Forum, Ladismith 26Feb2019).

A bit from:

The Cloud
by Percy Byssche Shelley

I am the daughter of Earth and Water,
And the nursling of the Sky;
I pass through the pores of the ocean and shores;
I change, but I cannot die.
For after the rain when with never a stain
The pavilion of Heaven is bare,
And the winds and sunbeams with their convex gleams
Build up the blue dome of air,
I silently laugh at my own cenotaph,
And out of the caverns of rain,
Like a child from the womb, like a ghost from the tomb,
I arise and unbuild it again.

(written late 1819, early 1820)
