1. New or rare AcANTHACEiE from German South-West Africa. 



Mr. T. G. Een's remarkable collection of Damaraland plants, 

 acquired by the Trustees of the British Museum in 1879, has been 

 mentioned several times in this Journal, and the recent discovery 

 of a small overlooked bundle of Acanthace® is sufficient warrant 

 for the following further notice. No full list is given, but only 

 the rarer plants are referred to, and those which seem to be new 

 described. 



Ruelliopsis damarensis, sp. nov. Caule repente subtetragono 

 sparsim albido-hispidulo mox minute puberulo, foliis oblanceolatis 

 obtusis basi in petiolum brevem angustatis subsessilibusve leviter 

 crassiusculis pilis paucis patulis hispidia albis exemptis glabris, 

 floribus secus ramulos brevissimos dispositis, bracteolis seu foliis 

 floralibus lineari-oblanceolatis obtusis calyci subasquilongis, calycis 

 lobis inter se aliquanto inzequalibus adusque \ connatis linearibus 

 obtusiusculis marginibus hispide ciliatis, corollas pro rata parvae 

 tubo superne gradatim amplificato extus minute puberulo liinbi 

 lobis late obovatis obtusissimis, staminibus inclusis, antherarum 

 loculis aequalibus oblongis basi mucronulatis, pollinis granis sub- 

 sphaeroideis circa 12-costatis 3-porosis, ovario late oblongo com- 

 pressiusculo apice microscopice puberulo ceterum glabro, stylo 

 puberulo, ovulis quoque in loculo saepissime 3, capsula oblonga 

 juxta apicem attenuata apice obtusa. 



Ramuli floriferi summum 1-0 cm. long. Internodia solemniter 

 2-0-3-0 cm. long. Folia ± 2-0 X 0*5 cm., in sicco dilute viridia ; 

 petiolilati, summum 0'3-0*4 cm. long. Bracteolae circa 1-0x0-2 cm., 

 pilis hispidulis perpaucis exceptis glabrae. Calycis tubus circa 

 0-4 cm., lobi ± 0-9 cm. long. Corolla extus puberula, in toto 

 1-5 cm. long; tubus 1*0 cm. long, basi 0-2 cm. faucibus 0*7 cm. 

 diam. ; lobi 0-5 x 0-45 cm. Filamenta vix 0-2 cm., antherae *egre 

 3 cm. long. Capsula circa 0-9 cm. long., 0*25 cm. lat. Semina 

 quoque in loculo saepe (nee nisi fallor saepissime) 2, ambito oblongo- 

 ovata, villosa, 0-3 cm. long. 



Aberrant from the genus by reason of the calyx tubular below, 

 the ovary cells with three ovules (instead of four), and the at least 

 often 4-seeded capsules. Judging, however, from the enlarged 

 ovules of flowers from which the corolla has already fallen, the
