FURTHER CONTRIBUTION TO OUR KNOWLEDGE 
Matroosberg; near Laaken Ylei, 5500 ft., Nov., 1917, Dr E. P. 
Phillips, 1966! (in Herb. S.A. Museum, 11766). 
Yar. pseudohybrida. 
Frutex humilior, ad 0-3 m. altus. Folia imbricata, late ovata vel 
latissime elliptica, obtusa, 3-5 — 4 mm. longa, 2-5 — 3 mm. lata, margine 
superne sparse glanduloso-crenulata. Capitula 5 — 8 mm. diam. Flores 
rosei; pedicelli vix 1 mm.; bracteolae filiformes, ciliatae, circiter 2 mm. 
longae. Petala 4 mm. longa. Staminodia anguste spatulata, 3 mm. longa, 
glabra. Stylus filiformis, 5 — 7 mm. longus, inferne patenter pubescens. 
Matroosberg, 6500 ft., Jan., 1897, A. Bolus (Herb. Guthrie, No. 
4395 !) (in Herb. Bolus). 
The two or three large glands which subtend the individual leaves 
suggest this plant’s alliance to A. adenocaulis, E. and Z., but the 
capitate inflorescences and petaloid staminodes place it in section 
Diplopetalum from whose members it is at once distinguished by its 
subtending glands, flattened and short ovate leaves and large marginal 
leaf-glands. 
Both type and var. Buchu are robust plants, and the leaves when 
rubbed especially in the variety Buchu exhale a strong Buchu-like 
odour. Variety pseudohybrida is a much more dwarf plant, with more 
imbricate and larger leaves and with the facies of A. imbricata forms. 
I suspect it to be a natural hybrid between A. alpina, Schlechter, and 
A. decora, both of which grow together on the Matroosberg at approxi- 
mately the same elevation. Dr E. P. Phillips, who examined the 
variety Buchu, in a ms. note mentions that the lower flowers in the 
inflorescences are perfect, whereas the upper are only male. 
A. Sonderiana, A. Burchellii proxime accedit, sed distinguitur foliis glabris, 
pro ratione brevioribus latioribusque, rarius in tria dispositis, ' apice 
subacutis, pedicellis brevioribus, sepalis petalisque eglandulosis, his 
apice haud penicillio praeditis. 
Fruticulus gracilis, dense divaricato-ramosus, partibus junioribus 
ubique puberulis, ramulis ultimis griseo-brunneis, gracilibus, dense 
foliatis. Folia ascendentia vel patula, breviter petiolata, anguste 
elliptica, subacuta, 4 — 6 mm. longa, 1 — 2 mm. lata, coriacea rigidaque, 
utrinque puberula et eglandulosa, subtus costata, pallide viridia, margine 
saepe valde revoluta (sicco), incrassata, punctato-glandulosa. Flores 
rosei (sicco) axillares, interdum solitarii vel in umbellas terminales, 
2 — 5-floras, dispositi, pedicellis ad 3-5 mm. longis, patenter puberulis, 
basi bracteolatis. Calyx parvulus, 1 — 1-5 mm. altus, minute puberu- 
lus, lobis anguste obovatis, dorso superne obtuse carinatis. Petala 
sessilia, obovato-elliptica, rotundata obtusave, ad 3 mm. longa, 1 mm. 
lata, glabra. Stamina 2 — 3 mm. longa, glaberrima. Staminodia anguste
