55. Mesembrianthemum (§11 Teretifolia) pachypodium Kensit, 1. c. 



p. 152. — M. molliter pubescens foliis semi-teretibus vulgo acutis; 



floribus solitariis longe pedunculatis pedunculis ebracteatis crassis; ca- 



ycis segmentis inter se inaequalissimis; stylis 6 erectis carnosis. — 



Herba subacaulis undique breviter et molliter griseo-pubescens; folia 



erecta demum patentia vaginato-connata semi-teretia apicem versus 



leviter carinata acuta vel rarius subobtusa inaequalia, majoribus 6 — 10 cm 



longis, 0,8 — 1,4 cm diam., minoribus 5,5 — 8 cm longis, 0,5 — 1 cm diam.; 



flores solitarii longe pedunculati, pedunculis erectis subcompressis 



ebracteatis crassis basin versus attenuatis, 5,5 — 10 cm longis, apice 



0,5-0,8 cm diam.; calyx gradatim in pedunculum attenuatus, segmentis 



6 erectis e basi lata lanceolatis crassis inter se perinaequalibus exteriori- 



bus 2,7 — 4 cm interioribus, 1,2 cm longis; petala 3-seriata linearia dilute 



rosea basin versus alba ad 2 cm longa, 0,15 cm lata; glandes 6 di- 



stincti; stamina staminodiaque oo; ovarium supra convexum 0,8 cm diam., 



stylis 6 erectis subulatis carnosis 0,3 cm longis. — Cape Colony, 



between Muis Kraal and Ladismith, fl. Nov., N. S. Pillans, 898! (in 



herb. Bolus). — This has the ebracteate peduncle of the § Calamiformia, 



but the softer spreading leaves of the § Teretifolia. It is allied to M. 



calamiforme Linn., and the little-known M. teretifolium Haw., from both 



of which it is distinguished by its short, soft, close grey pubescence, 6 



cleft calyx and 6 styles. — Prom the former it also differs in having 



the leaves acute, soft, and spreading, the peduncle longer and much 



thicker, and longer and thicker calyx segments.

 minutis carnosis. — Suffrutex glaberrimus glaucescens; rami decum- 

 bentes ramulis erectis compressis foliosis; folia subconnata erecto-in- 

 curva demum patentia compresso-triquetra acuta mucronulata anguhs 

 carinalibus minute serrulatis ad 5 cm longa, 0,6 cm crassa (ab angulo 

 laterali ad angulum carinalem metiente) ; flores 3-nati pedunculati, pe- 

 dunculis 1 cm longis lateralibus ad apicem duabus bracteis foliaceis 

 3 cm longis praeditis; calyx turbinatus subcompressus, segmentis 5—6 

 inaequalibus lanceolatis longe acuminatis, longioribus carinatis, brevion- 

 bus basi fusco-membranaceo-marginatis, 1,5—2 cm longis; petala sub-o- 

 seriata linearia albida 0,7 cm longa; ovarium supra planum 0,7 cm

 angulata, 1 cm diam. — Cape Colony, Skurf Kop, near Somerset
