Oct. 1926, N. S. Pillans, 5696. FI. Jan. 1927. 
Described from one living specimen which flowered in Mr Pillans’ 
garden. Closely allied to A. noctiflora, L. Bolus (= M. noctiflorum, L.), 
but differs in the more rigid habit of growth, much shorter, almost globose 
leaves, and the vespertine flowers. 
Aridaria noctiflora, L. Bolus, comb. nov. = Mesembrianthemum noctiflorum, L. 
Mesembrianthemum multiseriatum, L. Bolus. Glabrum, ramis elongatis 
radicantibus, internodiis convexo-curvatis 2-5 — 3-5 cm. longis, ramulis 
erectis, 5 — 6 cm. longis; folia obtuse carinata, sed tamen lateraliter sub- 
compressa, supra plana, acuta, lateraliter visa leviter ampliata supra 
medium, lateribus subconvexa, basi breviter connata, glauco-viridia levia, 
1-5 — 1-8 cm. longa, 1-5 mm. lata, ad 2-5 mm. diam.; flores solitarii 
diurni, 4-4 cm. diam., pedunculis 1-3 — 2-3 cm. longis, medio bracteatis; 
receptaculum turbinatum, sat asperum tuberculis sparsis; sepala 5, acuta, 
inter se subaequilonga, 5 — 6 mm. longa, 3 late membranaceo-marginata, 
membrana brunnea; petala 6 — 7-seriata, sat densa, linearia, inferne 
angustata, acuta vel acuminata, omnia rosea, 0-5 — 2 cm. longa, 0-5 — 
2 mm. lata; stamina erecta, mox subdiffusa, apice 4 — 5 mm. diam., 
filamentis pallide luteis, supra basin barbatis, ad 3 mm. longis, antheris 
pollineque aureis; discus inconspicuus annularis crenulatus; ovarium 
supra leviter convexum, stigmatibus 5 crassis subulatis abrupte acuminatis,

Described from living specimens received from Dr Muir in flower, 
October 1927. The general appearance recalls M. sociorum, L. Bolus; 
but the present species is readily distinguished by the petals in many 
series ( multiseriata ), the absence of staminodes, erect stamens becoming 
somewhat diffuse, and the shorter and stouter stigmas. I have previously 
confused this species with M. sociorum, L. Bolus, in placing La Grange’s 
plant, of which I had dried material only, under the latter.
