DECADES PLANTARUM NOVARUM AUSTRO-AFRIOANARUM. 431 



characterized by the want of interposed scales between the pappus- 

 bristles, the totally hispidulous achenes, and the purple (not blue) 

 ray-flowers.

 D. Ber<jianai Lk. & Otto ; acaulis vel e basi 1-2 ramulosa ; foliis 

 basilaribus rosulatis, ovato-ellipticis vel ovato-oblongis, basi in 

 petiolum laminae fere ffiquilongum angustatis, obtusis, margine 

 paucicrenatis vel paucidentatis, utrinque glabris, textura tenuiore, 

 petiolo incluso, l'5-3 cm. longis, caulinis minoribus breviter petio- 

 latis ; pedicellis axillaribus filiformibus, glabris, erectis vel adscen- 

 dentibus, folia multo excedentibus, 3-5 cm. longis; calycis segmentis 

 lineari-lanceolatis acutis glabris, 0*3 cm. longis; corolla bicalcarata, 

 tubo late campanulato, lobis snbtequalibus rotundatis calcaribus 

 conicis obtusis pendulis, c. 0-4 cm. longis ; filamentis subfiliformi- 

 bus glabris, antheris 4 perfectis, minutis ; stylo subfiliformi glabro, 

 c. 0-1 cm. longo ; capsula lineari c. 1-3 cm. longa, glabra, medio 

 fere 0*2 cm. longa, stylo filiformi coronata ; seminibus rotundatis

In regione austro-occidentali: In saxosis montium pone Montagu 

 Pass, in ditione George, solo arenoso, alt. c. 2500 ped., Sept. 1896; 

 Dr. A, Penther. 



The fourth species in the genus with spurred, not saccate flowers, 

 differing from D. Thimheryiana Spr., D. tanyceras E. Mey., and 

 D. nana Diels, by the conical, not filiform spurs, which are only 

 twice as long as the corolla, thus forming somewhat a connection 

 between the spurred and the saccate species of Wettstein's section 

 AxUlares. The rose-coloured flowers are about the size of those of 

 D. Bergiana Lk. & Otto. 



57. Orthosiphon serratum, sp.n. Caule ramisque tetragonis 

 villosis, bene foliatis ; foliis patentibus vel erecto-patentibus ovatis 

 vel obovatis vel ovato-ellipticis breviter petiolatis, margine serratis, 

 utrinque puberulis, petiolo villoso incluso l*5-2-3 cm. longis, medio 

 fere 08-1 cm. latis ; racemis elongatis, verticillis, 6-10-floris; 

 bracteis parvulis roseis, ovatis acuminatis, puberulis, pedicellis 

 tequilongis vel paulo longioribus ; pedicellis patentibus, filiformibus 

 puberulis, 0-5-0-6 cm. longis ; calyce campanulato puberulo, basi 

 obtuso, corolla} plus duplo breviore, post anthesin valde ampliato, 

 patulo ; corolla 1-2-1-5 cm. longa, tubo subcylindrico puberulo, 

 labio superiore oblougo-obtuso, c. 0-4 cm. longo, vix 0*2 cm. longo, 

 concavo, labio inferiore oblougo 3-lobulato, 0-4 cm. longo, c. 0'3 cm. 

 lato, tubo intus antice miuutissime hispidulo ; staminibus exsertis, 

 filamentis filiformibus, superioribus altius adnatis glabris, inferioi'i- 

 bus dimidio inferiore sparsim hispidulis, antheris reuiformibus ; 

 stylo filiformi glabro, cxserto, stamina superante, seminibus ro- 

 tundatis, pallide brunneis, sublfevibus. 



In regione austro-occidentali : In collibus lapidosis prope Bar- 

 berton (Transvaalia)), alt. c. 2800 ped., Sept. 1889 ; E. K. Galpin,

A very distinct species, easily known by its serrate leaves, and 

 the corolla, with the two lower stamens hispidulous at base.
