49 J. H. MAIDEN. 
L. ovata, R. Br. and L. longifolia, R. Br., also Australian 
plants, likewise exhibit marked stains. 
Strychnos psilosperma, F.v.M., N.S. Wales and Queens- 
land, affords a purplish stain, not so intense as Logania. 
OLEACE. 
Jasminum simplicifolium, Forst. Specimens from New 
South Wales, and Lord Howe Island exhibit a greasy-looking 
grey stain. 
MYRTACEA. 
Some species of Eucalyptus exhibit a greyish stain, which 
does not appear to he an oil stain. Instances are H. virgata, 
Sieb., and its variety obtusiflora; also E, Luehmanniana, 
F.v.M. 
POLYGALACEA. 
Comesperma retusum, Labill., C. sylvestre, Lindl., and 
C. ericinum, DC., stain the paper purplish. This tends to 
confirm the close affinity between these three Hastern 
Australian species, already ascertained on morphological 
grounds. 
The stain is also seen in C. flavum, DC., and C. calymega, 
Labill., two Western Australian species. The stain is of 
considerable persistence, it being well marked in Dr. 
Leichhardt’s specimens collected in 1843. 
The stain is most marked in C. retusum so far as my 
specimens go. I have also observed that in some specimens 
(e.g., C. ericinum) the purplish stain is succeeded by a dull 
brown one. This opens the enquiry as to how long the 
purple stain persists as such and when it changes colour 
in the cases in which it appears to change with age. 
RANUNCULACEA, 
Clematis pubescens, Huegel, a Western Australian species 
affords a purplish-brown stain which I[ notice in no other 
species. | |
