PHANEROGAMS — PROFESSOR BAYLEY BALFOUR. 205 



but in Kew Herbarium there is a second species, undescribed, found by 

 Welwitsch in Angola, and we have now a third from Socotra. The discovery 

 of our Socotran species necessitates slight emendations in the generic character 

 as given by Bentham and Hooker, to wit,— the habit is shrubby as well as 

 herbaceous, and the stamens may be glabrous as well as villous, with ciliate 

 anthers.

Nom. Vern. 'Ouhereteh (B.C.S.). 



Socotra. Rare on the slopes of the Haghier hills, at an elevation of 

 about 3000 feet. B.C.S. n. 398. Schweinf. n. 634. 



Distrib. Endemic. 



In this handsome shrub we have another plant of this family, interesting 

 from the point of view of distribution, and affording further striking proof 

 of the close affinity of the south African and this northern flora. The fruit 

 in our plant is much larger and more obliquely acuminate than in the south 

 African species, and the loculi are nearly equal at the base, but towards the 

 apex one rapidly aborts. 



We found this on the top of Sicante peaks behind Tamarida. Schweinfurth 

 has it from Kischen. It appears to be rather uncommon. 



12. XYLOCALYX. 



Xylocalyx, Balf. fil. in Proc. Roy. Soc. Edin. xii. (1883), 84. 



Calyx campanulatus, ad medium v. altius 5-fidus, fructifer accrescens lignascens, laciniis 

 angustis. Corollte tubus vix exsertus, superne ampliatus, paulum incurvus ; limbus patens, 

 lobis 5 latis integris subaequalibus 2 posticis interioribus. Stamina 4, didynama, exserta ; 

 antbera; liberae, glabra, per paria approximate, loculis distinctis parallelis rectis, altero 

 cujusque antbera? tenuiore. Stylus filiformis, apice stigmatoso leviter incrassato obtuso ; 

 ovula in loculis numerosa. Capsula basi globosa, apice compressa, calyce aucto inclusa, 

 loculicide debiscens, valvis integris medio septiferis. Semina numerosa, obcuneata, testa 

 foveolata. — Suffrutex rigidus, lignosus. nanus, minute aculeolatus, siccitate nigricans.
