villosule. Flores vix usque ad lO em. diam. Calycis lobi 0:4 em: 
long., extra mox molliter pubescentes. Petala vix ultra 0:2 em. 
long, extus villosula ; ligula laminam paullo superans, linearis, 
obtusa, vel plus minus abbreviata et petalum totum ad laminam 
minutam ovatam vel ovato-laneeolatam planam sepe reduetum. 
Filamenta O1 em. long., basi dilatata ibique libera. Staminodia 
omnino inter se libera, lanceolata, vix 0:3 cm. long., villosula. 
Ovarium glabrum, granulatum. Capsule iguotæ. 
This plant has given me much trouble, mainly on account of 
its petals. It is, in fact, a synthetic type, since the differences 
in the petals characteristic of the tribes Buettneriez and Lasio- 
petalez are met with here, and even in the same flower, The petals 
typical of the former tribe are prominent organs, with a large 
concave base and an elongated, more or less linear appendage or 
lafhina: those of the Lasiopetalex, if present at all, are small and 
scaly,and without trace of a lamina. The petals of Zulingia coacta 
are never of any size, but the lamina is sometimes relatively 
well-developed, and this side by side with petals which may show 
but a trace of a lamina or even be reduced to a simple scale. 
In all other respects, with the trifling exception that the stami- 
nodes are quite free at the base, instead of being connate and 
adnate to the stamens, the present plant is a typical Jtulingia ; 
but, inasmuch as the union is very slight in the case of R. salvi- 
folia, Beuth., 1 cannot consider this to warrant the establishing of 
a new genus in an order already, to my judgment, too much 
divided up generieally. 
Owing to absence of fruit, it is impossible to indicate the 
affinity of Zt. coacta. At first sight it looks not unlike A. pannosa, 
R. Br., but the leaves are smaller and differently shaped, and the 
inflorescence is more congested. The floral peculiarities above 
mentioned are, of course, weighty points of divergence. 
This plant was found only in one place, which a bush-fire had 
passed over some time previously. Plagianthus repens (p. 179) 
also grows here, and I saw it nowhere else. 
RULINGIA LOXOPHYLLA?, F. Muell. Near Kilkenny soak, June. 
An ascending subsbrub, up to 3 feet or so. Flowers yellow. 
The specimens to hand have buds merely, so that I find it 
impossible to name this without a query. 
KERAUDRENIA INTEGRIFOLIA, Steud. Siberia soak, January (in 
fruit). Between Uladdie soak and Yilgangie claypans, March
