Grevillea Rogersi, nova species. — In capite Borda, insula 

 Kangaroo Island, in solo arenoso crescens. 



Fiutex iiumilis intricate ramosus. Folia in brevissimis late- 

 ralibus ramulis conferta, similia fasciculo 4-5 mm. longa, 

 angusto-lanceolata dense revolutis marginibus, saepe 

 curvata, durae texturse et dense tecta brevibus et conicis 

 asperitatibus subtns lanata. Flores solitarii, vel in um- 

 bellis paucissimis floribus in brevibus foliosis lateralibus 

 ramulis; pedicelli circiter 7-8 mm. longa. Corollse tubus 

 12-13 mm. longus, pars inferior leviter dilatata, glaber 

 in exteriore parte, intus inferne barbatus ad fundum 

 puniceus, obtusi et revoluti lobuli subflavi. Torus 

 obliquus. Hypogyna glandula semi-annulata. Ovarium 

 dense villosum, breviter stipulatum. Styla erecta quum 

 flores decidissent, circiter 2\ cm. longa; stigma lateralis. 



A low, dense, intricately-branched shrub about 18 to 30 

 in. high as seen, with terete rather thick branches covered 

 when young with crisp white hairs. Leaves densely crowded 

 on very short lateral shoots so as to appear clustered, rarely 

 alternate, and more distant on some elongated shoots, 4 to 

 5 mm. long, narrow-lanceolate, acute, with margins so closely 

 revolute that the under-side is mostly concealed, often 

 curved, of hard texture and densely covered on the upper 

 side with short conical asperities : woolly-hairy on the under- 

 side. Flowers solitary, in pairs or in very few-flowered um- 

 bels, terminal on the short lateral shoots, the pedicels slender, 

 about 7 to 8 mm. long, sparingly hairy. CoroUa-Uihe 12 to 

 13 mm. long, the lower part slightly dilated, pink to scarlet, 

 6-veined, glabrous outside, with a tuft of hairs inside near the 

 base, the upper part of the tube with the short obtuse lobes 

 revolute and of yellowish colour. Torus oblique. Hypogynious 

 gland semi-annular. Ovary densely villous, shortly stipitate. 

 Style straight after flowering, about 2 J cm. long, sparingly 

 hairy in the lower half ; stigmatic disk lateral. Fruit ovate- 

 oblong, about 13 mm. long, glabrous when old. Seed scarcely 

 winged. 



This interesting new species belongs to Section iii., 

 Plagiopoda, but is not closely allied to any described species 

 known to me. The peculiar clustered, hard and rough leaves 

 are unique in the genus : they remind somewhat of the leaves 

 of Dendrohiuni cucumerinum. It seems strange that such 

 a remarkable species should have remained undiscovered until 

 now, but Dr. Rogers writes that this part of Kangaroo Island 

 has been little visited by collectors on account of the diffi- 

 culty of reaching the place by water or by land. Dedicated
