Ca Jills inferne radicans, procumbens, dein erectus, dichotomus, spitha- 

 mreus, penna corvlna parum crassior, ramis elongatis apice acutis. Folia 

 quadrifariam arete imbricata, erecta, rigida, ovata, acuminata, paululum 

 incurva, rigida, glabra, subnilida, plerumque rufa, rarius pallide viridia, basi 

 paululum producta, dorso carinata, marginibus subinflexis, obsolete lacero- 

 ciliatis. Capsules axillares, majusculse, folio paulo latiores, reniformes, bi- 

 valves flavae. Spondee minutre, flavce. 



As a species this may be considered allied to my L. rufes- 

 cens (Icones Plantarum, vol. i. tab. 36) from the same coun- 

 try, but it is quite distinct. The leaves are erect and closely 

 imbricated in four ranks, and with such regularity that the 

 keels of the leaves . form four continued lines or angles, and 

 between these are four flat sides, so that the stems and 

 branches have a perfectly square appearance.
