der Kulonisation wurde sie als »Swan River Broom« den Ansiedlern all- 
gemein bekannt. Das noch extremer xeromorphe C. spinosum scheint im 
Südosten zur Entwicklung gelangt zu sein. 
Comesperma scoparium Steetz (B. I. 443). 
Caules luteo-virides; sepala azurea, petala lateralia viridia violaceo- 
maculata. — Species in lutoso-arenosis ad regionis auslro-occidentalis fines 
interiores haud infrequens. Praeter stationes in »Flora Australiensie 
enumeratas eam vidimus in distr. Avon pr. York (D. 2919) nec non in 
distr. Irwin pr. Watheroo et Mingenew. Species fortasse pr. totam Ere- 
maeam profusa. 
Comesperma spinosum F. v. M. (B. L 144). 
Floris mensurae corrigendae: pedicellus circ. 3—4 mm long.; sep. 
exter. subfusca 1,5—2 mm long.; sep. inter. dilatato-cordata azurea 6—7 mm 
diamet,; pel. exter. 7 mm long., inter. 5—6 mm long. Fruetum non vi- 
dimus. — Species humilis horrida orientem versus progreditur in ditiones 
sinum Esperance Bay attingentes, ubi vidimus pr. Graspaich in lutoso-are- 
nosis flor. m. Nov. (D. 5313). 
Comesperma volubile Lab. (B. L 144). 
Quam plantam pulehram vidimus in distr. Avon pr. Mogumber in 
collibus glareosis flor. m. Aug.; nec non pr. Newnorcia in silvis glareosis 
Euealypti reduncae flor. m. Aug. (D. 3963). 
Specimina haee saepe vix volubilia sed humo prostrata ramosissima 
ramis nonnunquam suberectis. Cum collectiones Gilbertianae quaedam in 
distr. Avon haud procul a rivo Moore River effectas esse appareat, C. 
paucifolium Turez. formam nostram signare existimamus. Drummonn ipse 
iu eadem regione collegit; itaque specimina sua nonnulla caulibus »brevibus, 
flexuosis suberectisve« (B. T. 144) insignia inveniuntur. Quas formas non 
pecore, sed condilionibus quibusdam climatieis ortas esse censemus. 
Comesperma eiliatum Steetz (B. I. 144). 
Priori admodum affine videtur; capsulae forma vix diversa. 
Comesperma integerrimum Endl. (B. L 145). 
Quam speciem in distr. Irwin pr. Greenough River in acacietis apertis 
glareosis obtinuimus fl. m. Sept. (D. 4208); jam F. v. Mürter in eadem 
fere regione cam adnolaverat. Quo loco flores non lutei, sed viriduli pe 
talis interioribus purpurascentibus ornati observabantur. 
Comesperma Drummondii Steetz (B. 1. 1 45j. 
Orientem versus in distr. Coolgardie longius progreditur, ubi legimus 
baud procul a Southern Cross in arenosis lapidosis fruct. m. Nov. (D. 5605; 
Comesperma confertum Lab. (B. L 147). 
Descriptio Dë srgant incompleta. Flores non caerulei (ut B. L 442 in 
lavi specierum dicti, sed rosei. Praeterea varietate C. birtali Steud.
