The Kew Herbarium contaius a suite of specimens of this. species, 
collected in Arabia Felix by Schweinfurth himself. | Two of these bear 
the vernacular name ** Chaddasch” or * Chaddesch.” I presume that 
this is the plant identified as B. abyssinicum " Deflers. The identity 
of Schweinfurth’s with the Abyssinian plant is not obvious, and it 
may conveniently be maintained as a distinct species. Sehweinfurth 
remarks that myrrh is not collected from B. abyssinicum in Abyssinia, 
and tbe only evidence that I have scen that it yields "Kj produet of the . 
`~ sort is the label of a specimen collected by Speke and ^r EE which | 
bears the remark “ Frankincense shrub, fencing’ by gar 
A specimen of a plant stated to yield myrrh i by Captain 
Hunter in the neighbourhood of Aden seems to me also identical with 
Schweinfurth’s. ‘The evidence appears to point to the conclusion that 
in the Fadhli district myrrh may be yielded by both Balsamodendron 
Myrrha and B. simplicifolium, while the latter may be accepted as the 
source of Yemen myrr 
to Hadramaut m yrrh; we have the evidence of the specimens 
ciliated in 1893-4 by Mr. Theodore Bent, who was asked to give 
particular attention to the subject. It can har rdly be doubted that they 
are referable to B. Opobalsamum (Kew Bulletin, 1894, p. 330). 
AFRICAN BDELLIUM. 
This drug, which is associated with myrrh, but, as fur as East Africa 
appears to have been generally identified with the drug to whieh 
MIT originally gave the name, and which was derived from West 
Royle (Mat. Med., ne d. 387) says Dor te cose afri- 
canum, Arnott “ found ici west of Afica , occurs also in Abyssinia, 
having been found in the flat country of the "Adel It yields African 
bdellium, or that impo into France from Guinea and Sen ‘ 
cor M. Perottet. M. Adanson, raat in his travels in 
the Senegal, mentions it by the name of Niotout, as producing

Guibourt (Hist. Nat. des drogues simples, 4e ed. iii, 472) says 
that *ilen vient aussi d'Arabie qui parait ótre de méme nature." 
With regard to Balsamodendron iru the plant producing it, he 
adds “ilest probable qu'il traverse l'Afrique. de part en part, et rien 
n'empéche de penser qu'il ne eroisse i ay en Arabie.' 
Dymock (Pharmacogr. Ind. i, p. 310) says:—'*to a sn extent 
resembles myrrh, but is of a darker colour, less oily, and has 
odour destitute of the aroma of myrrh;” an ' further hanana 
bdellium is strongly bitter and has hardly. any aroma.’ 
The most detailed description is, however, nm by Parker (Pharm. 
Journ., 3vd ser, x., p. 82) :—'* African .Bdellium is met with in large 
tears like Opaque Bdellium, but the granulation is "m coarse, and t 
surface is traversed by deep cracks. It is very hard ; the conchoidal 
fracture appears slightly opaque, of a dull bluish stony hue, with a
