hracts, paired but connate stalklets, finally deciduous petals, not very long style 

 and dry moderately compressed fruits. — Verf. gibt die Unterscheidungs- 

 Merkmale dieser Gattung von Kermadecia, Euplassa, Panopsis und Macadamia 

 an. Die einzige Art ist H. pinnatifolia, am Tweed (C. Fawcett). 



Helipterum Frenchii, bei Menilyalya unweit der Shark-Bay (J. F o r r e s t). 



. (1. c. 1883. March.) 



Neue Arten: 



Hibiscus Haynaldii, Quellen des Menilyalya gegen Sharks-Bay hin (J. 

 Forrest), mit H. Pinonianus verwandt. Verticordia Forrestii, unweit des 

 Gascoyne-River (J. Forrest), mit V. spicata und lepidophylla verwandt; V. 

 Jamesonii, Gascoyne-River (J. F o r r e s t), mit V. picta, pennigera und Cunning- 

 hamii verwandt. 



Helipterum Kendallii wird jetzt zu Podolepis gebracht; neue Standorte 

 werden mitgetheilt. 



Oncinocalyx nov. gen. inter Labiatas et Verbenaceas intermedium : Tube 

 of the calyx at first broadly obconical, at last semi-ovate , 10-nerved; lobes 

 equal , subulate , hooked. Corolla hardly exceeding the calyx in length; lower 

 Up trifid, its middle-lobe obovate-cuneate ; lateral lobes somewhat shorter than 

 the middle one, as well as the lobes of the upper lip oblong-semilanceolar, and 

 equal to them in length. Stamens 4 , didynamous , shorter than the corolla, or 

 two of them hardly long er ; filaments linear-subulate ; anthers all dorsifixed, 

 almost renale, 1-locular, 2-valved. Stigmas subulate, recurved, half as long as 

 the style. Ovary slightly 4-lobed at the top, 4-celled, with 1 ovule in each cell. 

 Fruit enclosed in the calyx-tube , quite dry, depressed but hardly lobed at the 

 summit, seceding into 4 trigonous-ovate fruitlets. Seed soUtary, affixed near 

 the middle. Testa pale, membranous. Albumen none or exceedingly scanty. 

 Cotyledons plan-convex , oval; radiale inferior, obverse conical, half as long as 

 the cotyledons. — A herbaceous or perhaps somewhat shrubby plant of rather 

 toll growth, slightly downy; branches qiiadrangular ; leaves opposite, linear, 

 rather long , recurved along the margin; the pairs somewhat distant ; flotvers 

 very small, usually from 2 to 3 in each axil, on short stalklets; bracteoles 

 linear; calyx-tube not quite so long as the lobes; corolla seemingly pale; 

 fruitlets oti the inner side with shallow excavations from the base to beyond 

 the middle. — This genus mediates the transit from Verbenaceae to Labiatae ; 

 it diifers from Teucridium , to which it is nearest allied , in the bristly and 

 hooked calyx-lobes, in the not long exserted stamens and in the very short 

 style. . . The character of the calyx-lobes is almost unprecedented both in 

 Verbenaceae and Labiatae, although some approach to it is offered by the 

 genera Phryma and Notochaete. In some respects Oncinocalyx is allied to 

 Hyptis, which includes also a few species with similar calyces. — 0. Betchei,
