 1894 (specimen authenticum Muellerianum in Herb. Kewensi), 



Descriptio Muelleriana haud est optima, nam stratům pruino- 

 sum glaucum (tametsi tenue) et mericarpium interdum utrumque 

 evolutum hand memoratur. Setae hispidae in caulibus dispersae 

 forte sunt glanduligerae, quod e speciminibus siccatis, in quibus 

 setae hispidae apice facile franguntur, vix est eruendum. — D. 

 Croninianus fructibus parvis alis undulato-flexuosis insigniter ornatis 

 facillime dignoscitur.

Annuus, pusillus erectusque pilis patentibus glanduligeris hirsutus, 

 foliis paucis minutis trifidis, involucri foliolis late linearibus acutis 

 pedicellos circiter aequantibus, mericarpiis minimis obscure

Der (leider unvollständigen) Originaldiagnose Müeller's nach 

 eine sehr merkwürdige Art, die schon durch ihre winzigen Früchte 

 sehr gut charakterisiert ist. Da ich selbst die Pflanze nicht unter- 

 suchen konnte, lasse ich noch ausser der angeführten Übersetzung 

 der Originaldiagnose noch folgende Bemerkungen F. v. Müeller's 

 folgen : 



„Whole plant above ground about 2 inches high according to 

 an only specimen secured; root almost as long, simple, downward 

 capillary. Leaves including the pétiole only 74 ^^ Vs ^^'^^ ^^^S» 

 Flowers not obtained. Styles extremely minute, with capitellar 

 Stigmas. Fruits on pedjcels of about Vs i°ch length. Fruitlets 

 much shorter than the pedicels, somewhat demidiate, the ridglets 

 concealed." 



„A remarkable plantlet, similar to minute forms of D. pusillus, 

 but with fruits very much smaller than in any other congener, yet 

 bearing well developed albument, hence neither deformed nor of ab-
