Besters Vley, prope Witzies Hoek, in terra Orange Free State, 

 alt. 6500 ped., Jan. 1894, H. G. Flanagan, No. 2067 ; H. Bolus. 



One of the finest species of the Pachycarpiis section, for which 

 I am indebted to Mr. H. Bolus and Mr. H. G. Flanagan, who 

 discovered it during their recent trip to the Mont aux Sources, near 

 Besters Vley, in the Orange Free State. As in many other species 

 of the genus, the length and width of the middle lobe of the 

 corona-scales is somewhat variable, being sometimes shorter than 

 the corolla, or equalling it, sometimes longer. The colour of the 

 flowers seems to be about as in Gomphocarpusgrandifionis Dene., but 

 the different corona brings our plant nearer to G. concolur Dene, 

 and G. Schimianus Schltr. (in Engl. Jahrh. ined.). 



36. Asclepias mashonensis Schltr., n. sp. Herba erecta, 

 simplex, gracillima, c. 40 cm. alta ; caule tereti basi glabrescente 

 apicem versus bifariam puberulo, supra medium distanter foliato, 

 basi subnudo ; foliis patentibus anguste linearibus acutis, margini- 

 bus saepius revolutis, 7-9 cm. longis, internodia subasquantibus vel 

 paulo superantibus; floribus speciosis in umbellis subextra axillari- 

 bus alternantibus pauci-(3-4)fioris, folia baud jequantibus ; calycis 

 segmentis lanceolatis acutissimis, glabris, quam corolla multo brevi- 

 oribus, 0-2 cm. longis ; corolla lobis erecto-patentibus ovato- vel 

 obovato-oblongis obtusissimis, quam gynostegium duplo longioribus, 

 1-3 cm. longis, medio 0-7 cm. latis; coronse foliolis erectis sub- 

 membranaceis, circuitu obovatis, concavis apice acuminata iuflexis, 

 gynostegium jequautibus ; antlieris oblongis, marginibus cartilagineis 

 basi vix.ampliatis, subfalcatis, loculos vix a^quantibus, appendice 

 hyalino transverso late ovato obtusissimo, apice in stigma inflexo, 

 marginibus loculorum altius rotuudato-excisis ; polliniis paulo com- 

 pressis oblique falcato-oblongis obtusis apice paulo angustatis, 

 caudiculis divaricatis filiformibus, polliuia longitudine aequantibus, 

 basi conspicue dilatata, glandula brevi rhomboidea infra medium 

 adnatis.

This is the first Asclepiad known to me from the vast country 

 lying between the Limpopo and the Zambesi, as yet totally un- 

 explored. It is a very pretty plant, with the slender habit of G. 

 trimcatus and G. expansus, but differing from all the described 

 species in the structure of the corona. The flowers are dark
