peduncle. Calyx 5—8-parted. Ovary globose. Style very short. Stigmas 3—4, spreading andrecurved. A native of New Spain, between Venta de Acaguisocla and Mojonera, on the road fromAcapulco to Mexico . Nee states that it is considered one of the largest oaks in New Spain; and thatit has a-dense head of innumerable branches. The acorns are s arcely bigger than a pea, and nearlycovered by the cup, which is clothed with blackish scales. (Ace, as quotef in Rees’s Cycl.) Hum-boldt calls it. one of the most majestic trees of New Spain; and it is as remarkable for thebeauty and singularity of its leaves, as it is for the grandeur and nobleness of its general appearance.
