It is rare in a moist limestone forest at 100–600 feet altitude on north coast of Puerto Rico.[3][4] This plant can also be found on islands such as St. Thomas and St. John in the United States Virgin Islands and in Tortola and Virgin Gorda of the British Virgin Islands.[5][6][7] DescriptionMountain guava is a wild relative of guayaba, commonly known as guava (Psidium guajava). It can be distinguished by opposite and nearly round thick and leathery leaves that are 1½ -2¾ inches in diameter. They are thick/leathery and almost stalkless. Smaller flowers are located at the ends or at the sides of the twigs that are about ½ inch across. Their round fruit is about ¾ inch in diameter, with calyx lobes at their apex. The mountain guava flower color is green and white and blooms in the spring and summertime. The plant is evergreen and can grow in height approximately 2.4 to 3.7 meters (8–12 ft) tall. It was denoted in 1976 as a small tree that is capable of growing to 20 feet tall.[7] References1. ^{{cite web|url=http://www.ipni.org/ipni/idPlantNameSearch.do?id=600710-1 |title=IPNI Plant Name Details |publisher=Ipni.org |date= |accessdate=2017-04-27}} 2. ^{{cite web | title=Psidium amplexicaule Pers. | publisher=USDA PLANTS | url=https://plants.usda.gov/core/profile?symbol=PSAM | access-date=December 12, 2017}} 3. ^{{cite book | last=Sciences | first=New York Academy of | title=Scientific Survey of Porto Rico and the Virgin Islands | publisher=The Academy | issue=v. 6 | year=1930 | url=https://books.google.com/books?id=ZfEeAQAAIAAJ | access-date=December 12, 2017 | page=26}} 4. ^{{cite book | last=Liogier | first=A.H. | last2=Martorell | first2=L.F. | title=Flora of Puerto Rico and Adjacent Islands: A Systematic Synopsis | publisher=Ed. de la Univ. | year=2000 | isbn=978-0-8477-0369-2 | url=https://books.google.com/books?id=ISlUCW8p5GcC&pg=PA143 | access-date=December 12, 2017 | page=143}} 5. ^{{cite book | last=Britton | first=N.L. | title=The Flora of the American Virgin Islands | publisher=New York Botanical Garden | series=Contributions from the New York Botanical Garden | year=1918 | url=https://books.google.com/books?id=EJMYAAAAYAAJ&pg=PA74 | access-date=December 12, 2017 | page=74}} 6. ^{{cite book | last=International | first=Rare Fruit Council | title=Tropical Fruit News | publisher=The Council | issue=v. 27-29 | year=1993 | url=https://books.google.com/books?id=fEVMAAAAYAAJ | access-date=December 12, 2017 | page=24}} 7. ^1 {{cite book | last=Little | first=E.L. | last2=Woodbury | first2=R.O. | last3=Wadsworth | first3=F.H. | last4=Service | first4=United States.
