uses both. Winter uses eighteenth century forms as a rule, 
but his lacrymans is a hybrid. 
Saccardo (Syl. Fung.) uses classical forms as a rule, but, 
probably from carelessness, is very inconsistent. He writes 
Piri, Pirolae, campester, paluster, Silvester. But sylvatica and 
sylvana ! He has sometimes lacrymans, and sometimes lacri- 
French authors usually prefer Pirus — but sylvestris and syl- 
vatica. Vesque, however, has Pyrus. 
Of American authors. Gray always consistently uses eight- 
eenth century forms. Watson (Index and Botany of Cal.) 
writes Pirus ; but sylvestris and sylvatica, and, curiously 
enough, the diminutive Pyrola. Coulter uses eighteenth cen- 
tury forms as a rule, but has the hybrid Sylvester. Britton 
uses eighteenth century forms consistently. 
It will be noticed that those who retain the eighteenth cen- 
tury Latin do so consistently, while those who attempt to sub- 
stitute classical forms do it capriciously and without system. 
There seems no good reason for this, and it is probably large- 
ly due to carelessness. At any rate, if Pyrus is to be spelled 
with an i, so should sylvaticus, sylvanus, and sylvestris, and 
the latter should have the termination ter. If eighteenth cen- 
tury forms are to be retained we should write lachrymans ; 
otherwise lacrimans. We cannot split the difference in this 
matter. — Roscoe Pound. 
The Pronunciation of Scientific Names. — The follow- 
ing are the rules for the pronunciation of scientific names, 
adopted by the Botanical Seminary of the University of Ne- 
braska. 
I- In general, all names of the branches, classses, orders, and 
families of the vegetable kingdom, and their subdivisions, and 
the names of all genera and species shall be pronounced ac- 
cording to the " Roman Method." 
n. Generic and specific names derived from un-Latinized 
personal names may, if difficult to pronounce as Latin, be pro- 
nounced according to the rules of the language from which 
they are derived. But even in these cases the Roman pronun- 
ciation is recommended if it can be used. 
ni. Latin \vords which have become Anglicized shall be 
pronounced as English. 
IV. The following is a conspectus of the Roman Method :
