! apical part, the smaller leaf being neither hooked nor deeply 

 keeled at the apex; when young, the tv/o leaves are closed together, 

 and then somewhat resemble the beak of an eagle in form; substence 

 firmly fleshy; surface smooth and velvety to the touch, microscop- 

 ically ruberulous, dull .erreen , but rrobpbly of a brownish or grey- 

 ish tint under natur?^! conditions, not dotted. Flower always pro- 

 duced in front of* the new pair of leaves, ^edicel li--S inches 

 long, erect, slightly'' compressed and somewhat 2-edged, 3-3-| lines 

 broad and 2* lines thick at the uprer part, slightly tapering down- 

 1/vards, velvety-piuberulous, green, '^alyx in bud end viewed from the 

 side with a somevrhat chin-like base in front, velvety-nuberulous ; 

 lobes ascending-spreading, the tvra larger 9-12 lines long and 4§- 

 5 lines broad at the base, narrowing to an acute apex, keeled dovm 

 the back and more or less concave and hooked or inciirved at the 

 anex; the four smaller lobes o-5§ lines long, ovate, obtuse, vvith 

 membranous edges. Corolla li-2 inches in diameter, expanded in the 

 daytime, more or less closed at night, and lasting 10-14 days, 

 pleasantly fragrant; petals numerous, free ,. spreading, in about t' o 

 series, rather lax, about 9 lines long and "4-line broad, linear, 

 acute, pure white according to ^t. ^'^ir, but in one of the living 

 flowers seen the white was faintly tinted with piniish-mauve, with 

 a darker midline, and the other white without the pinkish tinge, 

 so probably the colour varies, as it does in many species belonging 

 to the other genera. Stamens somewhat loose, 2^-Z^ lines long; 

 filaments white; anthers milk-white. .Glands of the disk blackish- 

 green. Stigmas 6, spreading, about It-line long, stoutly subulate, 

 acutej-^somev/hat bristly-plumose, f^.reen. Ovary in the flov/er en- 

 tirely superior, v/ith a broad base, becoming partly inferior in 

 fruit. Green, with 6 stout ribs, 6-celled. Oppsuie as described 

 under the genus, half inferior, about 5 lines in diameter when closed 

 and 7 line in diameter vjhen expanded; valves pallid within, v/ith 

 honey-coloured, expanding-keels ; the cells, instead of bing superior 

 and entirely above the level of the base of the inner side of the 

 calyx-lobes as tehy are in the ovary, are (in the capsule) inferior 

 and entirely belo'- the level of the' inner surface of the base of 

 the calyx-lobes, the velves alone being now above that level. Seeds 

 less than i-line, long, ovoid, smooth, pallid, vi'ith a brown point. 



Riversdale -^ivision^ In the ^lein ^-aroo, among white stones, 

 floi/^^ering in September and October, 1,200 feet above sea level, 

 Muir 3,892. 



Described from a living plant sent to me by Dr. J. Ivluir, this 

 being another of the many interesting new species that he has dis- 

 covered, iNhich shows how rich S^yth Africa must still be interesting 

 undiscovered plants. 



I do not know how this plant behaves in South ^tvioa , but from 

 Dr. Muir's statements about it, I imagine that the flovi^ers become 

 fully developed from their first appearance in about two months, 

 '"/ith me however, the process of their development has been exceed- 

 ingly sloxv; I first sav/ signs of flov/er-buds' 



at the end of August, 1926, but it was not until the fifth of ^^^iarch, 

 1927, that the first flower opened, being over six months in devel- 

 oping. Evidently this is the effect of the colder temperature of 

 our climate, and I expect that the flower-buds appearing v/ith the 

 new pairs of leaves at the end of February, 1927', will develop 

 into flowers before they are six months old, as the v/armer season 

 is now approaching (this is v/ritten on i-iarch 14, 1927). This plant 

 appears to flower very freely, as fresh flowers are appearing on 

 every new growth on my specimens.
