Navarretia, R. & P. (1794)= Gilia, R. & P. (1794) = Collomia, 
Nutt. 
The first of Ruiz and Pavon’s names has priority of place over 
the second, and should be used if the genera are united. 
Macrocalyx, Trew. (1761) = Ellisia, L. (1763). 
Marilaunidium, Kuntze = Nama, L. (1759), not L. 1747. 
Nama, L. (1747) = Hydrolea, L. (1762). 
Cerinthodes, Ludw. (1737) =Mertensia, Roth. (1797). 
Cynoglossospermum, Sieg. (1736) = Lappula, Hall. (1745) = LEchi- 
nospermum, Lehm. 
Haller’s name is in my opinion the first available. 
Lithocardium, L. (1735) = Cordia, L. (1737). 
A Systema name. 
Morelosia, Liav. & Lex. (1824)=Bourreria, P. Br. (1756), not 
Beurera, Ehret. (1755). Bourreria and Beurera are named 
for the same man. 
Volvulus, Med. (1791) = Calystegia, R. Br. (1810). 
Physalodes, Beehm. (1760) = Pentagonia, Fabr. (1759) = Nicandra, 
Adans. (1763). 
Dr. Kuntze does not use Fabricius’ name here because Meehr- 
ing employed Pentagonia for a different plant in 1730." This is, 
however, a year ahead of the Genera Plantarum and in my view 
leaves Pentagonia, Fabr. free for this genus. 
Adenostegia, Benth. (1836) = Cordylanthes, Nutt. (1846). 
Afzelia, Gmel. (1791) = Seymeria, Pursh. (1814). 
Capraria, L. (1737)=Scoparia, L. (1753)- 
Conradia, Nutt. (1834) = Macranthera, Torr. (1835). 
Name not available on the principle ‘‘ once a ince uss always 
a synonym,” for Conradia was employed by Martius in 1829 for 
another plant. 
Fistularia, L. (1735) = Rhinanthus, L. (1737). 
A Systema name. 
Globifera, Gmel. (1791) = Micranthemum, Michx. (1803). 
Monniera, P. Br. (1756) = Herpestis, Gaertn. (1805). 
Stemodiacra, P. Br. (1756) = Stemodia, L. (1759). 
NXuarezia, R. & P. (1794) = Capraria, L. (175 3), not L. 1737. 
Gelseminum,Weinm. (1742) = Tecoma, Juss. (1 789). Not to be con- 
founded with Gelsemium, Juss., which is a Loganiaceous genus,
