By Baeon Sir Y. ton Mueller and Professor E,. Tate 



[Read October 3, 1882.] 



Trymalium "UVayse, spec. nov. 



Batlier tall, erect ; leaves obovate-spatular, not large, nearly 

 flat, above glabrous, underneatb as well as the branchlets very 

 thinly grey- velvety ; stipules almost semilaneeolar, acuminate ; 

 panicles short, with several but not numerous flowers ; bracts 

 rather small persistent, nearly ovate-lanceolar ; pedicels gene- 

 rally not much longer than the flowers ; calyx-tube thinly vel- 

 vety, much shorter than the lobes, the latter glabrescent 

 outside, petals undivided, dilated uj^wards, gradually narrowed 

 into the base ; style exceedingly short ; stigma conspicuously 

 three-cleft ; disk glabrous. 



In the Grorge of the Onkaparinga, b}^ the river side, about 

 three miles above Noarlunga. Pr(?/! Tate. 



A. lax shrub, attaining a height of eight feet. Leaves usually 

 from one-half to three-fourths of an inch, but attaining to one 

 inch in length ; decurrent into a short petiole ; their vestiture 

 much appressed, but not silk}'- shining. Diameter of expanded 

 calyx about one-eighth of an inch ; segments greenish-yellow 

 inside. Petals longer than the stamens. Pilamcnts about as 

 long as the roundish anthers. Disk much depressed, slightly 

 crenulated. Ovary three-celled. Capsule ovoid, two lines 

 long and one and a half lines in diameter ; stellately pubescent, 

 and slightly convex at the top, but little elevated above the 

 adnate calyx-tube, and crowned by the persistent calyx lobes. 

 Cocci flrmly membranous, apparently indehiscent, slightly 

 wrinkled on the inner face. 



General appearance more like Pomaderris mi/rtiUoides and 

 P. vaccinifolia than any resemblance to congeners, unless in 

 its broad-leaved form to Trymalium Wichurce and to T ledlfolium. 



The species is dedicated to His Honor S. J. A¥ay, Chief Justice, 

 and President of the Eoyal Society of South Australia, through 

 whose active interest for the prosecution of phytographic 

 research the discovery of this and some other additions to the 

 Plora of South Australia is mainly due. 



T. Wayoi is apparently rare, as only one group of six bushes 

 is known for a length of several miles in the Gorge of the 

 Biver Onkaparinga. It was flowering profusely in the first 

 week of November, but does not seem to perfect its fruit, 

 inasmuch as not more than seven or eight capsules rewarded a 

 close search undertaken a month later.
