EXPLANATION OF PLATE 168.
1. Ipomaa racemosa (Roth, Choisy. J. staphylina
Roem. and Sch. and Choisy formerly), flowering branch,
natural size.
2. Detached corolla split open.
3. Calyx and ovary.
4. Ovary cut transversely, 2-celled with 2 ovules was made,
in each.
5. Mature capsule.
6. Capsule in state of dehiscence, 2-valved.
Obs. As this species rarely perfects its fruit those
shown figs. 5 and 6 are taken from another species, none
