50 PROCEEDINGS OF THE AMERICAN ACADEMY 



breviter bifido brevioribus ; antheris superioribus sajpe (non semper) 

 6 connective glanduloso-appendiculatis. — Rio Negro, North Patago- 

 nia, on the upland plain. This, I believe, occurs in the Hookerian 

 herbarium, in the collections of Tweedie and of Gillies, and was by 

 the latter called Verbena ruhiginoscr, a name never published, and now 

 preoccupied in Lippia. 



Clerodendron inerme, R. Br,, var. /3. Oceanicum: foliis majori- 

 bus (2J--5-pollicaribus) magis acuminatis ; calyce truncato denticulis 

 5 minutis ; cymis nunc 5 - 7-floris. — Samoan, Tonga, and Feejee 

 Islands. This must be Forster's Volkameria inermis, and perhaps 

 Sprengel's Clerodendron Commersonii. I have seen no intermediate 

 forms (though they probably occur) between this and the true G. 

 inerme of India, &c., which has smaller and blunter leaves, and, as 

 described by Schauer, a distinctly 5-toothed calyx, " dentibus lato-tri- 

 angularibus acutis." 



Clerodendron, sect. Tetrathtranthus. Limbus calycis et co- 

 rollas quadrilobus, fere regularis. 



Clerodendron (Tetrathtranthus) ovalifolium (sp. nov.) : 

 foliis ovalibus obtuse acuminulatis integerrimis basi subangustatis (cum 

 petiolo ramisque teretibus) glabris ; cymis plurifloris corymboso-pani- 

 culatis canescenti-puberulis ; corolla hypocraterimorpha, tubo (ultra- 

 poUicari) calycem obtuse 4-lobum pluries excedentibus, lobis 4 rotun- 

 datis inter se tequalibus stamina adsequantibus. — Feejee Islands. 

 Differs from the next somewhat in the foliage, but strikingly in the 

 shape of the corolla. 



Clerodendron (Tetrathtranthus) Amicoru^h {Clerodendron 

 Amicorum, Seem, in Bonplandia, 10, p. 249) : foliis ovali- seu cune- 

 ato-obovatis (9 - 11-pollicaribus) in petiolum brevem attenuatis inte- 

 gerrimis cum ramis subteretibus glabris ; cymis multifloris corymboso- 

 paniculatis canescenti-puberulis ; corollte tubo subinfujidibuliformi ca- 

 lyce 4-lobo quadruplo lobis ipsis duplo triplove longiori ; staminibus 

 modice exsertis. — Samoan and Friendly Islands. Corolla stouter, its 

 tube shorter (at most an inch long) and enlarging iipwax'ds, and the 

 limb larger than in the preceding. The tetramerous flowers remind 

 ns of Labillardiere's genus Oxera, of New Caledonia, but in all other 

 particulars it is a Clerodendron. Since the above character was drawn 

 up, Dr. Seemann has published the species as a new one, under the 

 same name, comparing it with C. inerme, but without noticing the 

 tetramerous character.
