the smallest of all phanerogamic plants of the world ; the 

 tallest specimen scarcely exceeds one-eighth of an inch. It has 

 not heen seen, though looked for, at any other locality. 



Kochia humillima is also new to the province, its proper 

 habitat being Victoria. It is a small plant, and is becoming 

 very rare through the cropping of the sheep. 



Plagiantlms glomeratus occurs only in the northern part of 

 the Hundred and beyond, but occasionally a stray specimen is 

 seen near Ardrossan. It is a much smaller plant than its 

 congener, P. sjyicatus. The latter onty flourishes once, and 

 once only, on newly-burnt soil, the seed then becoming latent, 

 till another fire starts it into growth. Acres of dead stalks, 

 five to seven feet high, may be seen in fertile parts of the 

 scrub, and not a single young plant comes up for years. 



Dodoncea Tepperi, F. v. M., is a new species, distinguished by 

 its dense low growth, very small leaves, and a quadrilateral 

 speckled fruit. Only one plant has as yet been found on a 

 stony hillside, near Ardrossan. 



Goodia medicaginea is new for the locality, and was obtained 

 from Kilkerran by Dr. Engelhardt, of Maitland. 



Acacia acinacea has only been seen here on the low plain at 

 Black Point, but was formerly observed in great plenty near 

 Monarto and at Truro on stony hills. It has a silvery grey 

 leaf. 



Hydrocotyle rugulosa had not before been known out of W. 

 Australia, but Baron F. v. Mueller remarks, has perhaps been 

 overlooked and taken for H. capittaris. It occurs sparingly in 

 the mallee scrub of Muloowurtie and the sandhills near 

 Maitland. 



Helichrysum obtusifolium has been only obtained in one 

 specimen near Ardrossan. Its leaves appear to die off when in 

 full bloom. 



Stylidium calcaratum is new for the locality. It is a very 

 small plant, scarcely a quarter of an inch long, but the stalk is 

 about one and a half inches, and the flower very large for its 

 bearer. It was profusely abundant for the space of a few 

 square yards near the sandhills N. of Maitland, while round 

 about not any could be discerned. 



Thelymitra camea is one of the rarest of our orchids, and 

 also new for the locality, it having before only been found 

 about Mount Lofty. The specimen was found growing under 

 the protection of an old brush feuce in Yorke Valley. Under 

 similar circumstances Chamcescilla corymbosa was found. 



Jjyperanthus nigricans has nowhere else been observed by me 

 than among the sandhills near Maitland. It is a beautiful 

 orchid, that obtained its specific name from drying perfectly 

 black. Acianthus exserhis and Caladenia camea occur often in
