Seeds very unripe. The sepals are, as in several species of Byschoriste, united into 

 a tube by a scarious membrane one cell thick, which disrupts at a touch when the 

 fruit is formed. Botanists who have boiled the calyx or applied a reagent find it 

 5-6epalou8 nearly or quite to the base.

I do not feel sure that this is other than S.fellatensis, with the corolla-tube not 

 yet fully elongated. 



20. LANKESTEBIA, Lindl.; Benth, et Hook. f. Gen. PI. ii. 1083. 



Calyx divided nearly to the base; segments 5, subequal, linear. 

 Corolla (in African species) orange, withering off* dull red ; tube long, 

 linear, hardly dilated even at the top ; lobes 5, subequal, obovate, more 

 or less oblique, contorted in bud. Stamens 2, with 2 small rudi- 

 ments often added ; anther-cells muticous ; pollen short, elhpsoid, 

 reticulated ; stopples 3. Ovary glabrous or nearly so, covered with dis- 

 coid glands ; ovules 2 or 1 in each cell ; style thinly hairy ; stigma 

 capitate or short-oblong, more or less 2-lobed. Capsule 2-seeded (where 

 seen), ellipsoid, fiattened, base contracted, solid ; seeds covered by 

 hygroscopic hair. — Shrubs 1-3 ft. high. Leaves entire. Flowers in 

 subglobose heads, or in long strobilate spikes or panicles ; bract long, 

 ovate or linear ; bracteole linear, hardly as long as the calyx. 



Species 3-4 in Africa, 17 in Asia {Dcedalacanthus, T. Anders.). This genus is that 

 part of JErantliemum, Linn., separated off generically by R. Brown, and superficially 

 so resembles Eranthemum that it was retained in Eranthemum by Nees. It is 

 distinguished Istly by the contorted corolla-lobes, 2ndly by the reticulated pollen, 

 3rdly by the hygroscopic hairs on the seeds. Dcedalacantkus h said by Bentham to 

 differ from Lankesteria by having included stamens ; but in Dcedalacantkus 

 splendens, T. Anders., the anthers are exserted h-^ in., very much more eiserted than 

 in any Lankesteria. Lindau separates these genera by the pollen, which he says is 

 round in Dcedalacantkus, 3-winged in Lankesteria. But in the type species, 

 L. jparv^ora, the pollen is only slightly trigonous.
