I have some different descriptions, this time they are about plants. Also, do you think that could be possible for an antilopine-like descendant of the goat or of the sheep to live in the Andean plateau?
Atlantic cherry (Eugenia atlantica) In South America, the genus Eugenia survived the Holocene and a new species appeared, the Atlantic cherry. This species is native to the forests of the Atlantic coast of South America. Being a common component of the Atlantic forests, they provide food to many species.
is a large shrub or small tree with a conical form, growing slowly to 8 m high. When bruised, crushed or cut, the leaves and branches have a spicy resinous fragrance, which can cause respiratory discomfort in susceptible individuals. The leaves are without stipules, ovate, glossy and held in opposite pairs. New leaves are bronze in color, maturing to a deep glossy green, up to 4 cm long. During dry season the leaves turn red.
Flowers have four pale pink petals and are borne on slender long stalks, with a conspicuous central cluster of white stamens ending in yellow anthers. Flowers develop into rounded fruits 3 cm long, starting out as green, then ranging through orange, scarlet and finally dark red as they ripen. Its seeds are dispersed mostly by fruit eating birds and bats.
Montane jamelan (Neosygyzium montano) During the Holocene, the man introduced many species, animal and vegetal. The tree Sygyzium cumini was one of these introduced species. In the Neocene, this species give rise to the genus Neosygyzium with the type species being the montane jamelan. The word jamelan (jamelão) is a common name used to its ancestor in Brazil. The montane jamelan is native to the montane forests of the Atlantic Coast of South America. Their fruits are consumed by many species of these areas.
Montane jamelan is a large tree, typically reaching 30 m of high and can live more than 100 years. Its leaves and twigs are glabrous and the bark is dark brown and fairly smooth, with little relief or texture. The leaves are lanceolate, 2 cm to 4 cm broad, 10 cm to 20 cm long, pointed, base cuneate with hardly any petiole, lively red when growing, but glossy green on attaining full size. The flowers are in small terminal clusters, white or greenish white, the long, numerous stamens giving them a diameter of 8 cm. The flowering period of this tree is in the end of the spring.
Its fruits develop during the summer and resemble large berries, being 15 cm long; the fruit of the genus Neosyzygium are drupaceous. The fruit is oblong, ovoid. Unripe fruit looks green. As it matures, its color changes to pink, then to shining crimson red and finally to black color.
Other species in this genus:
Lowland jamelan (Neosygyzium esculentus) This species reach the same high of the montane jamelan, however is native to the lowland forests of the Atlantic coast of South America. Its fruits are also large, being 27 cm long and magenta colored.
Aromatic guava (Psidium aromatica) In South America, the guavas (Psidium) survived the Holocene and a new species appeared, the red guava. This species is native to the tropical regions of South America. Across its occurrence areas, the fruits are used as food by many species.
The aromatic guava is a large tree, being capable to reach 28 m of high. The tortuous trunk has a smooth shell that peels off thin plates. The leaves are coriaceous and glabrous, up to 10 cm in length. The flowers are axillary, solitary and white. The flowering period occurs during the start of spring. The fruits mature when the first rains of summer start to fall.
The fruit consists of fleshy green colored berries which turn yellow when ripe. The surface is irregular, with 10 cm of diameter. Inside, there is a red pulp, containing dozens of small hard seeds. The four sepals of the flower are usually present at one end of the fruit. When the fruits are ripen, they exhale a strong sweet aroma which attract many animals to consume it, such as the puraheikai.

I was thinking if the soybean and wheat could have descendants in the Neocene. They are cultivated in South America and perhaps some wild descendants could exist in the savannas.
JOrnitho Wheat does have a descendant - the hamster's wheat in the chapter 87 "Adopted in Eden" (only Russian so far, sorry). But it is in Asia, though. As for the soybean, it seems to have no descendants.

I was thinking about some plants for Easter Island and I think that most of the species here would be introduced or were transported from South America. I thought about a species of giant banana tree. Do you have more ideas for plants in the island?
I have little knowledge about indigenous flora of Easter Island, but a descendant of pineapple would be great, if pineapple is introduced there by humans.

Yes, there is farms that produce pineapple in the island. Other introduced plants are the sweet potato, yam, paper mulberry and sugar cane. The surroundings of the lakes of the island are covered in totora reed.

So we can make a descendant there!

So, descendants of sweet potato and yam are quite plausible.

I was thinking that since these plants are in an island, they could be different than their ancestors. The benana tree would be high like a palm tree, but with smaller fruits, while the pineapple could produce two or three fruits. Any ideas for the descendants of the sweet potato and yam?

This only show how I'm terrible in botanic hahahaha. It wasn’t my favorite subject in college, where I stayed only with what the professors taught. I greatly prefer zoology of vertebrates. My idea about the banana was that it would be similar to the Musa ingens from Indonesia. It have the longest petioles of any tree, with 15 meters. In Neocene Easter Island, this giant herbaceous plant would be part an important part of the forests. Regarding the pineaple, maybe it could develop two structures wit multiple fruits on it, with each fruit being more protuding and colorful when ripe.

My mind was crossed with an idea of a large (about 5 m tall) pineapple bush with numerous, but small fruit, maybe also simplified in structure
I like that idea! Maybe the flowers are disperse in the bush and, rather than fusing in one single structure, becme each one a small fruit. I wonder which type of polinization this species could have. Another idea that I had for the island is the presence of descendants of the cocconut tree. These palms would also have developed smaller fruits.

JOrnitho Well, the pineapple blossom and fruit are too far specialized to become absolutely simple. They would rather remain complex, as they are now. Pollination by insects, surely.

descendants of the cocconut tree
Descendants of coconut palm are already present in neocene. But there can be more in other regions, as the coconut palm is widespread.

I see, but could they still have a reduced size and more than one structure in the bush? The small size could allow the pineapple to develop four structures with multiple fruits in its middle.

The isolation in Easter Island could allow them to become different from their relatives in other areas.

I do not quite understand. What do you mean by "structures"? Four fruit on one stalk? It's OK, but why four? Pineapple fruit are berries that merge into a large multiple fruit.

Yes, sure. The already existing coconut descendants I mentioned are on Hawaii, described in chapter 46 "The Green Pearl of the Pacific" (only Russian so far, sorry).

I wasn’t sure to how to explain it. I mean that this descendant of the pineapple could develop more stalks where the multiple fruits would appear after the merging of the berries. Or instead the plant could develop a branched central stalk where the flowers would appear and eventually merge in the multiple fruit. They could be small like that of the Ananas comosus var. microstachys.

Then, we have these plants in Easter Island: Rapa Nui coconut Giant banana Rapa Nui pineapple Yam (native name uhi) Sweet Potato (native name kumara) Totora reed (native name nga'atu) They will need some better names. Do you have suggestions? Also, I was reading that the island have Melia trees and guavas. They could also have descendants.
