Houston, &c., but not growing together with 
KRAMERIA. Professor A. Braun, after examining the flowers of species of this genus, has suggested that [4] 
the natural affinity of Krameria is with Leguminose, rather than Polygalacee. And, indeed, at least in K. lanceo- 
lata, the two lateral glandulous petals cover in estivation the stamens; they cannot therefore belong to an interior 
circle, as Bentham supposes. The ovary is one-carpellary (against the type of Polygalacee) and irregularly one-sided, 
like the ovary of Leguminose ; it is imperfectly bilocular, by the inflection of the placenta, as in some Leguminose ; 
but in both cases the cells are always side by side ; on the contrary, in Polygalacee one is before the other. Krameria 
may, then, be considered a pentandrous Lequminosa, where one or two stamina are abortive. In K. lanceolata, it is 
the lowest stamen, opposite the three connected petals, which is wanting; but, in some flowers, a sterile filament 
occupies this place; it corresponds with the free 10th stamen of most sapitiondaaots flowers, as the four others, which 
An account of the region in which Lindheimer collected, being by Gray, they are indicated by name only. As in 
contributed by Dr. Engelmann to Part Il. pp. 234-240, is the remainder of this part of the reprint, new Cactacee, 
omitted as of little botanical interest. Besides the species Cuscute, Euphorbiacee, Alismacee, Graminew, Asclepiader, 
here redescribed, the paper contains a number for which the and Loranthacee are omitted, the Souestpisens referring to 
authors are jointly responsible; the descriptions of these these orders having been brought together elsewhere. — Eps.
