DESCRIPTION OF A NEW SPECIES OF CHLOANTHES 

 FROM WESTERN AUSTRALIA ; 



By Baron von Mueller, K.C.M.G., M. Sc Ph.D., F.R.S. &c. 



Chloanthes Teckiana. 



Vestiture consisting of jointed partly branched and also gland- 

 ular hairlets, thus somewhat viscid ; branchlets cylindric ; leaves 

 all opposite, sessile, brittle, from lanceolar-ovate to narrow- 

 elliptical flat, distantly and rather deeply and bluntly serrulated, 

 equally green on both sides ; flowers, through decrease of size 

 of the floral leaves, constituting foliate racemes ; peduncles slender 

 one-flowered, axillary, solitary, finally somewhat longer than the 

 calyx, bearing two lanceolar or rhomboid bracteoles near the 

 summit ; calyx divided to near the base into lanceolar segments ; 

 corolla rather large, its tubular portion upwards turgid, inside 

 near the base bearing circularly very short dense white hairlets ; 

 its two upper lobes almost semi-orbicular and usually shorter than 

 the others ; lateral lobes semi-ovate ; lower lobe somewhat longer, 

 nearly rounded and often with a small terminal notch ; stamens 

 glabrous, the two longest only and slightly emerging ; anther-cells 

 bearing at their base a minute turgid appendage ; style and disk 

 glabrous ; stigmas short, narrow, pointed, unequal in length ; 

 fruit nearly globular, beset densely with very short white hairlets, 

 its base perforated ; primary dissepiment turgid towards the 

 middle and separating into two laminas ; secondary dissepiments 

 thin and slightly hollowed. 



Near Lake Deborah ; the specimens communicated by the Hon. 

 John Forrest, CM. G. 



Nearest allied to Chloanthes De7iisonii, which however has most 

 of its leaves ternately whorled and provided with sharper serra- 

 tures, the flower-stalks shorter, the calyx cleft less deeply with 

 more pointed lobes, the corolla considerably smaller and also 

 proportionately less turgid, the anther-appendicles hardly visible, 

 the fruit ellipsoid-obovate. 



With this new elegant shrub, of evidently rare occurence, has 

 been dedicatively connected the name of the Duke of Teck, 

 G.C.B., in appreciation of the powerful support, which His High- 

 ness, as President now of the Royal Horticultural Society of 

 England, is affording to the very meritorious pursuits of that great 

 union. The colour of the corolla, so far as can be judged from 

 the dried specimens, turns from violet into lilac. If Pityrodia 

 is to be maintained as distinct from Chloanthes, then this plant 

 should be placed into that genus.
