A Contribution to our knowledge of the Genus Agathosma, 407 
Allied to the preceding species from which it is distinguished by its 
prostrate habit, narrower lanceolate leaves which are obtusely glandular 
at the apex, large and more-flowered umbels, not ciliolate calyx-segments, 
almost glabrous petals and glabrous ovary. The specific name alludes to 
the farm Gustrow, which: abuts on Gardon's Bay and on which the writer 
has had the privilege of botanising, thanks to the courtesy of the owner, 
Mrs. D. Langschmidt. 
62. Agathosma orbicularis Bartl. and Wendl, 
Coast Region, Caledon Div.; Caledon, Zeyher! near Caledon, 
300 m, Sept. 1889, Bolus, 9910! 
A cotype of Thunberg’s is incorporated in the Shuttleworth Herbarium 
at the British Museum. : 
63. Agathosma minuta Schlechtendal. 
A robust specimen in the Brit. Museum gathered by Banks and Sol- 
ander in 1777 at the Cape of Good Hope, during Cook's memorable 
voyage round the world. 
64. Agathosma thymifolia Schlechtendal. 
: Coast Region. Uniondale Div.; on stony slopes of the Bothasberg, 
660 m, Aug.-Sept., Macowan, 560! Central Region. Somerset Div.; 
on a mountain above the spring of Commadagga, 6. July 1813, Bur- 
chell, 3324! 
-= 65. Agathosma lanceolata Dümmer, nov. comb. 
A. Wrigtii Macowan in Jour. Linn. Soc. Bot. XXV, 386, (1890); Diosma 
lanceolata Linn, Syst. 625 (1767), not Thunberg; Hartogia lanceolata Linn. 
Syst. 287 (1762). 
Coast Region. Cape Div.; Simons Bay, Wright! in rocky places 
of mountain-summits behind Simonstown,. 300 m, June 1884, Macowan, 
2550! Macowan, 555! 
This species differs from A. thymifolia Schlecht. by the „much longer 
and pilose petal-claw, the sterile filaments piloso-ciliate for two thirds of 
their length, and the much larger size of the plant“; superficially it resem- 
bles forms of A. rugosa Link. Linne's type-specimen is entirely in agree- 
ment with this plant; his other specimen which he doubtfully refers to 
this species, is typical A. rugosa Link. 
66. Agathosma glandulosa Sonder, l. c., p. 420. 
Coast Region. Malmesbury Div.; near Groene Kloof (Mamre), 90 m, 
Oct. 1878, Bolus, 4259! 
I have not seen the type of this species, but Bolus’ specimens agree 
well with the description of Sonder except perhaps that the leaves are 
relatively shorter. The same applies also to specimens in the British 
Museum gathered by Masson. 
67. Agathosma foliosa Sond., var. Schlechteri Dümmer, nov. var. 
Flores albidi; pedicelli circiter 2,5 mm longi cum ealyce creberrime 
. patenter puberuli. Calyx pedicello duplo brevior, segmentis late obtuseque 
` deltoideis eglandulosis. Petala 3 mm longa, laminis ovalibus inferne vix 
canaliculatis,
