Tatea nov. gen. Calyx tcith a semiovate soon hemispheric tube and five 

 somewhat uneqiml semiovate deltoid or finally semtorhicular leaves. Corolla 

 with very short Munt irregulär lobes of imbricate preflorescence and with a 

 Short tube inside bearded towards the middle. Stamens 4, inclosed, didynamous. 

 Filaments short , inserted near the middle of the corolla-tube. Anthers almost 

 cordate , longitudinally dehiscent , ivithout any appendage. Style singularly 

 short, deciduous. Stigma mimite. Disk none. Ovary bicelled , with a solitary 

 amphitropal ovule in euch cell. Fruit drupaceous , ovate-globular , clasped at 

 the base by the persistent calyx, perfectly two-celled , ttvo-seeded , or by evane- 

 scence of one of the ovules one-seeded. Placentae axillary, fixed to the middle 

 of the septum, moderately convex. Pericarp baccate. Endocarp bony, tvrinkled 

 or fnrrotved, not Splitting. Seeds oblique-ovate, impressed at the placenta, fixed 

 at the middle. Testa membranous, pale. Älbumen thin , amygdaline. Embryo 

 white, but little shorter than the albumen. Cotyledons plane-convex , free, 

 dotvnwards straight , upwards somewhat bent or twisted. Radicle very short, 

 almost globular, exserted , inferior. — A somewhat hairy herb, stemless or 

 ptroducing a very short stem , with creeping root-stock , with leaves opposite or 

 quaternarily crowded of comparatively large size of ovate shape of wedge- 

 shaped attenuation into their very short stalk or sessile base, and of upwards 

 many denticidation , with cymes or rather short peduncles , with narrow or 

 minute bracts , with small flowers and outside black drupes. — T. acaulis, 

 Arnheim Land in Nord- Australien , zwischen Bridge Creek und Mc Kinlay 

 River (R. Täte), unweit Yam Creek (Fo eis che). Die Pflanze ist trotz ihrer 

 Eiweiss führenden Samen besser zu den Viticeae als zu den Chloanthaceae 

 zu stellen und nähert sich einigermaassen Premna, zeichnet sich aber vor 

 allen Verbenaceen durch den Habitus einer stengellosen Gesneracee oder 

 Scrophulariacee aus. Köhne (Berlin).

Beschreibung folgender neuen Arten: 



Ficus Pinkiana, Trinity Bay; die Unterschiede dieser Species von F. sub- 

 glabra und F. Philippensis werden hervorgehoben und es wird auf ihre 

 Verwandtschaft mit F. excelsa Vahl , sowie auf die Schwierigkeit der Art- 

 abgrenzung in der 600 Species umfassenden Gattung hingewiesen. Helipterum
