(Lobelia Family) 
LOBELIA CARDINALIS L. Cardinal flower. 
LOBELIA INFLATA L. Indian-tobacco. 
Extracts were not repellent to the Japanese beetle. — lietager and 
Grant (277). 
L. inflate contains the alkaloid lobeline, the physiological effects 
of which closely resemble those of'nicotine. A 0.5- and a 0.25-percent 
solution of lobeline killed 100 and 70 percent of bean aphids, respec- 
tively, but a 5-percent crude alcoholic extract of the leaves and seeds 
proved only slightly toxic. — Tattersfield and coworkers (593 ) , 
LOGANIACEAE 
(Logania Family) 
GELSEMIUM ELEGANS Benth.

Scarone (353 ). 
GELSEMIUM SEMPERVIRENS (L.) Ait. Yellow jessamine. 
Honeybees visiting the flowers are poisoned, but only the young 
workers were affected.— Burns ide end Vansell (72) . 
SPIGELIA MARILANDICA L. Maryland pink. 
Extracts of the roots killed only 30 percent of the mosquito 
larvae tested.— Hart tell and Wilcoxon ( 188 ). 
STRYCHNOS IGNATII Bergius. Ignatia. 
Extracts from the dry beans were not repellent to Japanese 
beetle.— Metsger and Grant (277 ) . 
A mothproofing composition, containing an alkaloid or alkaloids 
from the seeds of this species, was claimed in a British patent by 
Ritter (No. 327,009) .— Roark (335 , p. 82). 
STRYCHNOS NUX-YOMICA L. Nux vomica. Strychnine tree. 
An extract was tested against four species of caterpillars. A 
5-percent spray killed on an average only 21 percent of the insects 
tested within 7 days, and a 1-percent spray killed only 12 percent.— 
Duke of Bedford and Pickering (53, p. 84).
