acute, glabrous, the floral ones not diftering. Flowers capitate, 

 6-8 in a cluster. Calyx somewhat thinly adpressecl-hairy, tube 

 3 lines, limb f line long, segments oval obtuse with incurved edges. 

 Stamens 8. Squanicne 8, glabrous, as long as the calyx segments. 



By the Signal Station. Aug., Wolietj Dod, 2928. 



Unlike any other South African species, but superficially much 

 resembling Arthrosolen laxus E. Mey.. for which it has not im- 

 probably been passed over. 



Hypodiscus capitatus Masters, sp. n. Stems csespitose, about 

 18 inches high, as thick as a crow-quill, erect, simple, subcom- 

 pressed, spotted ; leaf-sheaths fine, IJ-li- inch long, tightly con- 

 volute, coriaceous, shortly mucronate, with a rather slender obtuse 

 apex; male spikes 3-5-7, crowded at the apices of the stems, sur- 

 rounded by lanceolate, patent, spotted spathes, subglobose, each 

 about ^ inch long and broad ; bracts broadly ovate, subulate-mu- 

 cronate, coriaceous, reddish, with a pale mucro, the lowest empty ; 

 exterior perianth-segments linear-oblong, mucronulate ; anthers 

 linear apiculate ; female spikes 3-7, aggregate, each i inch long, 

 linear-oblong, 1 -flowered, spathes and bracts as in male, perianth- 

 segments hyaline, small, obtuse ; ovary oblong, tuberculate, sur- 

 mounted by an undulate cup-shaped disc ; styles two, thick, linear- 

 lanceolate, coalescing at the base into a stylopod. 



Roadside near Hout Bay. June-July, Wolley Dod, 2644, 2645. 

 (^ et ? . Dr. Thorn, in herb. Hook., under number 1060 J , wrongly 

 referred to H. albo-aiistatiis. 



Perhaps too near H. rugosus, but differing in its bracts being 

 less abruptly acuminate, the apex longer and paler, the segment of 

 the female perianth more obtuse, and the epigynous disc being cup- 

 shaped. 



H. Dodii Masters, sp. n. Stems ascending from a creeping 

 rootstock, about 6 inches high, slender, simple, subcompressed, 

 obsoletely rugulose ; sheaths at the base of the stem about 1^ inch 

 long, tightly convolute, coriaceous, with a rather slender longly 

 foliaceous-mucronate apex ; the others about f inch long, without 

 a mucro ; male spikes . . . . , female 1-2, spicately arranged at the 

 apex of the stem, each about | inch long, enclosed at the base by a 

 lanceolate coriaceous spathe, membranous at the edges ; perianth- 

 segments six, linear-lanceolate, membranous, equalling the trans- 

 versely rugulose fusiform-cylindrical ovary ; styles two, fruit in- 

 dehiscent, unilocular. 



Sternberg Plateau. July, Wolley Dod, 2720. 



Distinguished from its allies by its elongate perianth.
