DRAGON’S BLOOD TREE OF SOCOTRA. 623 
These have been turned to good account, but much still remains to be cleared 
up. Certain it is that red resins of different composition, and therefore 
probably derived from different sources, are in commerce, at least have found 
their way into our Museums, under the name dragon’s blood, and do not appear 
to be distinguished from one another. But I must leave Dr Doppre and Mr 
HeEnpeErson to tell their own story, and conclude this brief note with a technical 
description of the Socotran tree. 
Draceena Cinnabari, Balf fil. Arbor 25—pedalis trunco crassitiem 3 ped. 
attingente apice copiose ramoso ; foliis 1-2 ped. longis 1-14 poll. latis +4 poll. 
crassis sessilibus in apicem ramorum validorum confertis patenti-erectis firmis 
sed in juvenilibus seepe subrecurvis basi amplexicaulibus ad similitudinem piscis 
caudee expansis ibique 4 poll. latis rubescentibus, versus apicem gradatim 
attenuatis, supra concavis infra jugo medio prominulo convexo extremitate 
trigonis obtuse punctatis, ecostatis, glauco-viridibus margine concoloribus ; 
paniculis glabris pseudo-terminalibus multiramosis 1-24 ped. longis, ramis 
ramulisque divaricatis strictis, antepenultimis 9-12 poll. longis, penultimis con- 
tractis 2-4—floris, pedicellis validis 4 poll. longis supra medium articulatis ; 
bracteolis membranaceis longis acuminatis; perianthio sordido + poll. longo, 
segmentis oblongis vix. connatis, apice uncinatis ; genitalibus inclusis, filamentis 
subulatis antheris oblongis duplo-longioribus ; ovario oblongo stylum eequanti, 
stigmate trilobato ; baccis aurantiacis 4 poll. diam. nitidis, 
Nom. Vern. Arboris—Kharya ; Resinee draconis—Edah. 
Socotra, per insulam totam in montibus ultra 1000 ped. alt. crescens. B.C.S. 
No. 80. Schweinf. No. 550. Perry. 
The Nubian D. Ombet is separated from the Socotran plant by its less robust 
habit, more slender and shorter antepenultimate branches of the panicle, longer 
pedicels, non-acuminate bracteoles, and more delicate perianth, with commonly 
a stipitate ovary. 
D. Schizantha, from Somali Land, is easily diagnosed by its downy panicles. 
D. Draco, from the Canary Islands, differs in having compressed ensiform 
leaves, smaller bracteoles, greenish perianth, the segments of which are not 
uncinate at the apex, anthers relatively to the filament shorter, ovary commonly 
stipitate, and stigma capitate.
