ALABASTRA DIVERSA.— Part VIII. 



By Spencer Le M. Moore, F.L.S. 



(Plate 421.) 



Leurocline, 



Borraginearum e subtribu Lithospermear am genns novum (tab. 424 A). 



Calyx alte 5-pai-titus, segmentis liberis angustis inter se in- 

 asqualibus postico revera minore persistentibus. CorollaB tubus 

 cylindraceus, faucibus ampliatis intus nudis ; limbus 2-labiatus, 

 labio superiore erecto breviter 2-lobo, labio iuferiore breviter 3-lobo 

 patente. Stamina 5, faucibus iuserta, inclusa ; filamenta brevis- 

 sima; anthersB oblongs, obtascTe. Ovarii lobi 4, gynobasi planae 

 insert! ; stylus filiformis ; stigma breviter 2-lobum. Nucul^e 

 saepissime 4, trigonse, tuberculat^, areola plana basilari gynobasi 

 planas affixae. Fruticuli parvi, ramosi, liispidi vel verrucati. Folia 

 alterna. Flores mediocres, ex axillis superioribus solitatim 

 oriundi. 



This genus has all the characters oi Ecldocldlon, except that the 

 stamens are inserted in the throat of the corolla, and, its principal 

 raison d'etre, that the nutlets are fixed by a flat base to a flat (not 

 conical) gynobase. In this latter character, as also somewhat in 

 habit, it resembles Lobostemon, from which it differs in having an 

 irregular calyx with small posticous lobe, a distinctly zygomorphic 

 corolla, included stamens and bilobed stigma. Its position in the 

 order, as understood by Bentham in the Genera Plan ta rum, seems 

 to be next Sericosto)tia, from which, however, it is separated by 

 several important characters. 



Leurocline lithospermoides, sp. nov. Caule stricto mox 

 ramoso, ramis foliosis erectis rigidis glabris, foliis sessilibus lineari- 

 oblongis obtusis vel obtusissimis supra glabris subtus marginibusque 

 pilis brevibus hispidis basi albo-verrucatis obsitis, pedicellis sub- 

 nullis, calycis ampli segmentis a corolhe tubo superatis linearibus 

 vel lineari-lanceolatis acutis hispidis segmento postico nunquam 

 evanido, corollas tubo juxta medium coartato limbi dilatati lobis 

 rotundatis undulatis, stylo incluso, nuculis obtusis.
