3. Names borrowed from other languages than Latin or Greek 
and more or less Latinized: BERBERIS, TECOMA, CABOMBA, YUCCA, 
MAYACA. 
4. Plants named for persons, either by the addition to the per- 
son's name (often modified) of -a, -a, or by some such suffixed word 
as -anthus. 
5. Artificial compounds, invented by the authors, generally from 
Greek component parts, because of the ease of compounding in 
Greek, e. g., SERICOCARPUS, CAULOPHYLLUM. These are often care- 
lessly and incorrectly formed. In this sin Linnaeus and Rafinesque 
are among the chief offenders. Of about nineteen names ascribed 
by the sixth edition of the Manual to Rafinesque, three are formed 
from names of persons, one is unexplained, and fifteen are of his 
own concoction. Of these fifteen, ten are incorrectly formed! 
6. Names derived from those of other genera, including ana- 
grams: TriLisa (Ziatris), VERBESINA (Verbena), VALERIANELLA, 
CROTONOPSIS. 
All these names are by common convention put into a form more 
or less closely approximating to Latin, and are accompanied by adjec- 
tives in agreement with them according to Latin rules of gender. 
From the unity afforded by this thin veneer of Latinity any uniform 
system of accentuation must take its start. We should therefore 
enquire upon what principle Latin words are accented. For those 
whose recollection of Latin accent is less vivid than it once was I 
will summarize its principal rules. 
1. The penultimate syllable of a word if long is accented ; if not, 
the antepenult receives the accent. 
2. A syllable is long if it contains a long vowel or a diphthong, or 
a short vowel followed by x, z, or two consonants (except a mute or 
f followed by a liquid). Examples: 
a) vowel long: CaLopocon. 
b) diphthong: SUAÉDA. 
c) before x: Hypoxis. 
d) before z: I have noted no instance of this in the Manual. 
e) before two consonants: LITTORÉLLa, SvNÁNDRa, EPIPÁCTIS. 
Note that the combinations ch, ph, th (Greek x, q, 0) each 
count as a single consonant. 
f) before a mute or f + a liquid = BRACHYÉLYTRUM. 
As in all these cases except a) the length of the syllables is at
