pauci- v. multiflora, floribus omnibus t fertilibus v. nonnullis sterilibus. Involucrum 
cylindraceum v. turbinato-campanulatum, bracteis oc-seriatis imbricatis, interioribus 
rarius fere omnibus apice coloratis y. laminis coloratis radiantibus appendiculatis, ex- 
terioribus gradatim brevioribus appressis dorso sspe lanatis. Receptaculum planum, 
nudum.  Corolle regulares, tubulos:z, limbo parum ampliato 5-dentato.  Anthers basi 
sagittatz, auriculis parvis caudis tenuibus simplicibus v. setaceo-ramosis appendiculatis. 
Styli rami tenues, apice obtusi v. truncati. Achsmnia, in speciebus paucifloris unum 
solum, in multifloris fere omnia perfecta, leviter compressa, laevia, ecostata v. b-angulata, 
apice basique obtusa. Pappi setze 1-seriatz, liberz, sigillatim decidu:e, tenues v. apicem 
versus incrassato-dilatatce.—Frutices erecti v. divaricati, ericoidei, ramis sspe cano- 
tomentosis. Folia parva, sessilia, integerrima, coriacea, brevia v. subtorta, marginibus 
swpius incurvis, supra potius quam infra canescentia. Capitula parva v. mediocria, ad 
apices ramorum conferta, sessilia v. subumbellata, rarius solitaria. Corolle purpurew 
v. albide. —Achsnia glabra, sspe nitida. 
Species 20, Africz Australis incole. — Harv. et Sond. FI. Cap. iii. 265. 
Candolleus (Prod. vi. 249) Mealasiam ad species capitulis paueifloris reducit, quibus flores in 
capitulo infra 10 et sepius 4-6, quorum 1 fertilis, ezeteri steriles, et pappi setze (przesertím florum 
sterilium) haud copiosz, apicem versus inerassato-dilatate.  EnvTHROoPocoN, DC. Prod. vi. 254, a 
Harveio ad sectionem Me£alasie restitutus, species continet 2 Donianas, quibus flores im capitulo 
10-20 ex DC., 100-200 ex Harv. (nos infra 20 vidimus in M. wbellata, 50—60 in M. imbricata) ; pleri- 
que fertiles sunt et pappi setz copiosiores vix apice incrassatz.  ENDoLEUCA, Cass. Diet. xiv. 474, 
rite a Candolleo ad Metalasia: refertur. 
Lessing, Syn. Comp. 334, characterem Me£alasie imprimis ex ovario rostrato stipitatoque eduxit, 
rostro stipiteque pellucidis et demum in achznio maturo magis minusve evanidis. Nos in speciebus 
pluribus examinatis rostrum stipitemque frustra quzsivimus. An character ex specie quadam nobis 
ignota sumptus, vel in ovariis monstruosis v. male siccatis observatus ?
