Question: Which has more species, Hedysarum or Hyophorbe?

Context paragraphs:
Hyophorbe: Hyophorbe is a genus of five known species of flowering plants in the Arecaceae family, native to the Mascarene Islands in the Indian Ocean.

Hedysarum: Hedysarum (sweetvetch) is a genus of the botanical family Fabaceae, consisting of about 200 species of annual or perennial herbs in Asia, Europe, North Africa, and North America.

Hedysarum alpinum: Hedysarum alpinum is a species of flowering plant in the legume family known by the common name alpine sweetvetch.  It has a circumpolar distribution, occurring throughout the northern latitudes of the Northern Hemisphere.  In North America it is widespread in Canada and the northernmost United States, including Alaska.

Hyophorbe verschaffeltii: Hyophorbe verschaffeltii (the palmiste marron or spindle palm) is a critically endangered species of flowering plant in the Arecaceae family.  It is endemic to Rodrigues island, Mauritius, but is widely grown in cultivation.

Hedysarum boreale: Hedysarum boreale is a species of flowering plant in the Fabaceae, or legume family, and is known by the common names Utah sweetvetch, boreal sweet-vetch, northern sweetvetch, and plains sweet-broom.  It is native to North America, where it is widespread in northern and western regions of Canada and the United States.  The ssp.  "mackenziei" can even be found in the Canadian Arctic Archipelago.

Eskimo potato: The Eskimo potato is a type of edible plant that grows in the northern areas of Canada and Alaska.  It can be used in the state's famous Alaskan potato and egg breakfast tacos.  The plant's scientific name is variously attributed as either "Claytonia tuberosa" (Inuit: "oatkuk") or "Hedysarum alpinum" (Inuit: "mashu").  Both species have a range in the northern area of North America, have edible roots, and have been documented to have been used as a food source by Inuit peoples.  Due to its nutritional qualities, the eskimo potato is one of many edible foods listed in survival guides, such as the US Army's field manual "Survival", and is used in modern times to subsist in nature; for instance, Christopher McCandless used the plant as a food source while he survived in the Alaska wilderness.  However, while the tubers are edible, it is suspected that the ingestion of seeds from this plant caused McCandless' death.

Hyophorbe vaughanii: Hyophorbe vaughanii is a species of flowering plant in the Arecaceae family that is endemic to Mauritius.  Its natural habitat is subtropical or tropical dry forests.

Hyophorbe lagenicaulis: Hyophorbe lagenicaulis, the bottle palm or palmiste gargoulette, is a species of flowering plant in the Arecaceae family.

Hyophorbe amaricaulis: Hyophorbe amaricaulis (also known as Loneliest palm) is a species of palm tree of the order "Arecales", family Arecaceae, subfamily Arecoideae, tribe Hyophorbeae.  It is found exclusively on the island of Mauritius, and only a single surviving specimen has been documented in the Curepipe Botanic Gardens in Curepipe.  Thus, this is the most gravely threatened species there is, in any kingdom.

Hedysarum sulphurescens: Hedysarum sulphurescens, the yellow sweetvetch or white sweetvetch, is a perennial herb species.
