224 THE JOUBNAL OF BOTANY 



exactly as regards leaves with Nees's Balsamodendron Myrrha. 

 Moreover, " Mol-mol " is the Somali name for the gum-resin from 

 myrrh, so that apparently Engler makes the true myrrh plant a 

 variety of his G. Myrrha, vJiich yields no resin, has no aroma, 

 and possesses trifoliate leaves with much larger lateral leaflets 

 than the myrrh plant. This I explained in the Pharmaceutical 

 Journal for Jan. 14th, 1899, pp. 26, 27, giving illustrations of the 

 plants, and pointing out that Nees's specific name should be 

 retained, and that the plant which yields myrrh should be called 

 Commiphora Myrrha (Nees). As it is now necessary to introduce 

 correct nomenclature into the forthcoming new edition of the 

 British Pharmacopoeia, I venture to suggest that to save further 

 confusion the name Commiphora Myrrha Holmes should be 

 adopted as the name of the tree yielding Somali myrrh with the 

 synonyms Commiphora Myrrha var. "Mol-mol" Engl., excl. type; 

 Balsamodendron Myrrha Nees. It may be noted that the Somali 

 name " Mol-mol " is only applied to the gum-resin myrrh, but the 

 tree is called "Didin," pronounced "Didthin." An excellent 

 account of the myrrh tree and the allied species is given in N. E. 

 Drake-Brockinan's Somali-land, 1912. The Somalis distinguish 

 the myrrh produced near the coast-line on lower rocky ground as 

 Guban myrrh, and that produced on the inland range of mountains 

 as Ogo myrrh, but there seems to be little difference in the two 

 trees except in size. — E. M. Holmes. 



Authorship in the « Amo^nitates Academic js ' (p. 101). — A 

 note from W. Coxe's Literary Life and Select Works of Benjamin 

 Stilling fleet, ii. 185 (184) may be added to Dr. Jackson's paper : 

 it is appended to the opening sentence in the " Preface to the 

 Miscellaneous Tracts," which runs : — 



" The following pieces were selected from many others pub- 

 lished by several ingenious members of that great and hitherto 

 unrivalled school of Natural History, the University of Upsal in 

 Sweden, under the presidence of Linnaeus." 



The note is as follows : — 



" Linnaeus, Phil. Bot. p. 9, has these words, ' vid. dissert, 

 nostra de ficu." Now there is a piece in Amcenitates Academics, 

 vol. 1, on this subject, in which the matter referred to is contained. 

 This piece goes under the name of Cornelius Hegardt, though 

 Linnaeus plainly quotes it as his own. How far that may be the 

 case of all the other pieces in the Amcen. Acad. I cannot pretend 

 to say. But it is most likely from the practice in foreign univer- 

 sities, in relation to theses held for degrees, that they must, in 

 great part, be attributed to him at present. Mr. Stillingfleet after- 

 wards learnt from Dr. Solander that the materials of these pieces 

 were furnished by Linnaeus. He adds that the President 

 employed each of his disciples in studying and investigating the 

 nature of a plant, particularly in relation to soil, site, and aspect, 

 time of flowering and foliation, and to what insects it furnished 

 food. The result of these observations he threw into the form of 

 Essays, which were communicated to those who were to read disser- 

 tations on taking degrees, or on other occasions." — James Britten.
