| Hi, I took these on the Big Island of Hawaii, and I suspect this is an invasive species from the mainland. Thought it might be Ailanthus (which thankfully, I don't have growing in my back yard), but it doesn't look like it from the web. Anybody know?
PS The plant with the grassy plumes in the background is definitely an invasive, probably Phragmites australis, which is invading wetlands in the neighborhood! |

| I'm not an expert on tropical flora but I expect that you have taken a photo of a Black Wattle (Acacia mearnsii). |

| Looks similar to a Albizia, or silk tree.. Not certain though. : ) J |

| Smivies, this tree is not necessarily tropical. One thing that surprised me about Hawaii, was that there are plenty of temperate species from the mainland that are growing there (including the Phragmites in the background). At the top of the Mt. Kilauea caldera, there are open plateaus of very lean and acidic soil, which are being colonized by broom sedge - Andropogon virginicus. It is indigenous here and grows in the little meadow in my back yard! What an adaptable species, growing quite happily in zone 5 (or colder) and zone 11-ish. |

| Don't know about the plumes but the foliage looks like that of sugar cane and not common reed. The tree seedling might be the same as the trees behind. As elsewhere in the tropics Hawaii has numbers of different kinds of pea family trees and shrubs present, most of them not native. |
Here is a link that might be useful: Mimosoideae - Wikipedia, the free encyclopedia

| I don't think it's possible to ID it with any certainty from only the pictures provided. Most possibilities fall within the Mimosoideae subfamily, but I can also think of some that, although still in the Fabales order, don't. A picture of it in bloom would help narrow down the possibilities. |
|
| Thanks for the approximate id! Yes I think that these are seedlings of larger trees in the back ground. Perhaps some flowers would be needed to make an exact id? As for the plumes, that probably is sugar cane, as that land is abandoned sugar cane fields. The sugar cane industry on the big island was largely shut down by the mid 1990's. |
