74 BARON FERDINAND VON MUELLER. — RECORD OF 



Darwin, where subsequently Professor Tate of the Adelaide Uni- 

 versity professionally explored,- — this distinguished scientist 

 carrying on geologic and phytologic researches simultaneously. 

 Some time previously Mr. B. Gulliver was sent from the Botanic 

 Gardens of Melbourne, by the writer of these pages, on a collect- 

 ing errand with Captain Cadeil's expedition, and much earlier 

 Mr. Armstrong had formed an herbarium at and near Port 

 Essington for the Royal Garden of Kew. During the last few 

 years the director of the Botanic Garden at Port Darwin, Mr. 

 Maurice Holtze, has with a most praiseworthy zeal been engaged 

 whenever any opportunities did Occur, to add still further to our 

 knowledge of the native plants of Arnheim's Land, he being 

 occasionally aided by Mr. Paul Foelsche, and latterly also by a 

 young enthusiastic son. The Holtzean collections comprise now 

 nearly one thousand species, and it is my object, to submit to the 

 Royal Society of New South Wales from time to time, records 

 of novelties from his gatherings, some of his discoveries having 

 obtained publicity already. It is further hoped, that in a few 

 years a full list of the plants, indigenous to the extremest part of 

 North Australia, may become elaborated. 



DUNBARIA SINGULIFLORA. 



Weak, procumbent or somewhat twining, densely beset with 

 very short hairlets ; stems and branches thinly filiform ; leaves 

 quite small, on very short petioles ; stipules extremely narrow, 

 pointed ; leaflets from lanceolar-elliptical to oblique-ovate, of 

 rather firm consistence, granular-dotted beneath, recurved at the 

 margin, the two lateral leaflets on extremely short stalklets ; 

 stipelles none ; flowers axillary, always solitary, their stalk of 

 about the same length or shorter ; lobes of the calyx pointed, the 

 lateral two shortest, deltoid-semilanceolar, the upper two connate 

 to a bidenticular apex, the lowest hardly longer than these; petals 

 glabrous, the lowest conspicuously incurved ; fruit comparatively 

 large, very much compressed, elongatedly and obliquely elliptic- 

 lanceolar, without transverse impressions, but almost septate ; 

 seeds several, somewhat compressed, roundish, but at the base 

 truncate, outside black-brown ; strophiole conspicuous, almost 

 colourless, bisected. 



A delicate plant, with the aspect somewhat of Rhynchosia 

 glandulosa, probably quite herbaceous. Vestiture grey. Leaflets 

 |? — |- inch long, paler beneath, the dots copious, pale, hardly 

 shining and much concealed. Calyx scarcely -^ inch long, granular 

 dotted. Petals of about double calyx-length, deciduous, probably 

 yellow, the lower two sometimes twisted. Style capillulary, 

 glabrous. Fruit 1^ — 2 inches long, about ^ inch broad, with very 

 thin vestiture, without any basal stalk-like attenuation. Funicles
