 12 Australian, etc., — the general character of the grass flora being 

 Malayan or Indo-Malayan , with the northern and Australian features 

 most emphasized in the northern highlands. Seventy-two genera are 

 recognized, of which one only, Garnotiella is endemic.

The first paper deals with a small overlooked bündle of Acan- 

 thaceae, coUected by F. G. Ken in Damaraland. The following 

 new species are described: Ruelliopsis damarensis (peculiar in the 

 calyx being tubulär below, in the ovary-cells having only three 

 ovules and the offen 4-seeded capsules); Petalidiuni damarense (re- 

 sembles P. physaloides, S. Moore, but without stellate hairs, with 

 narrower, greener closely-pubescent bracteoles, longer coroUa-tube 

 etc.); P. Eenii (differs from P. Lepidagathis , S. Moore in the indu- 

 mentum, much smaller leaves of barren shoots, coroUa-tube dilated 

 above etc.); Blepharis grisea (with grey pubescence, linear-oblong 

 entire or weakly spinous leaves, few-flowered spikes etc.); Barleria 

 i^Prionitis) Eenii (with short interpetiolar spines, oblong-spathulate 

 bracts, small glandulär calyx etc.); B. (S Acanthoidea) jubata (nearest 

 B. eleganSy S. Moore, but differs in dense pubescence, small leaves, 

 narrow bracts and bracteoles etc.); Monechma eremum, (differs from 

 M. Nepeta, C. B. Cl. in the compact habit, smaller and narrower 

 leaves, larger corolla, longer capsule etc.); M. platysepalum (distinct 

 in its Short oblong obtuse leaves and relatively broad bracteoles and 

 calyx-lobes). 



In the second paper Orthosiphon (§ Virgati) Buryi n. sp. is de- 

 scribed; it differs from O. mollis , Bak. in the comparativety long 

 and slender pedicels, the longer calj- x-teeth , the longer corolla, etc.
