Soeotra. On the Haghier hills at a considerable elevation. B.C.S. n. 

 509. Schweinf. n. 612. 



A small and very distinct species. 



Order LV. SELAGINEiE. 



A small family of nine genera of herbaceous or shrubby plants, chiefly of 

 old world extra-tropical distribution, having their headquarters in south Africa, 

 but some occur in tropical Africa, Europe, and Asia. Represented in Soeotra 

 by one endemic genus. 



COCKBUENIA. 



Cockburnia, Balf. fil. in Proc. Roy. Soc. Edin. xii. (1883), 90. 



Calyx 5-fidus, tubulosus, lobis angustis acutis requalibus. Corollse tubus brevis, superne 

 ampliatus ; limbus 2-labiatus, patens, labio postico 2-lobato, antico parum longiore 

 3-lobato lobis subrequalibus. Stamina 4, didynama, supra medium tubum affixa, exserta ; 

 antberte versatiles, cunfluentes uniloculars, medio vix constricts. Ovarium 1-loculare, 

 1-ovulatum ; stylus apice minute bilobatus. Fruct. ignot. — Frutex incanus, ramis diffusis, 

 virgatus. Folia alterna, obovata, integerrima. Flores caesii, parvuli, in spicas breves 

 terminales srepe compositas dense conferti, singuli in axilla bractere sessiles, ebracteolati. 

 Bractere non involucratre, auguste lanceolate, calyce parum breviores, cum calyce hirtae. 



An interesting monotypic genus of this small family, distinguished from all 

 other genera except Globularia by its one-celled ovary. 



With this latter genus it has its nearest alliance in the order, and forms a 

 second member of the section which has hitherto embraced Globularia alone. 

 From Globularia itself it is excluded by many characters. Notably there is a 

 difference in habit and in the fibrous texture of our plants ; then the flowers are 

 arranged in spikes to which there are no involucrate bracts. The corolla is 

 unlike the corolla of the majority of species of Globularia-, being bilabiate with 

 a short tube and short limb, there are, however, sometimes corollas in 

 Globularia approaching it in form. Lastly, the anthers are hardly so con- 

 stricted as in Globularia, though there is a distinct grooving of the surface. 



Etym. After Lieut. J. G. Cockburn, 6th Royal Regiment, a member of our 

 expedition.
