Nine species of mosses are reported as new to the flora of Haiti. In 1958 Crum and Steere published an annotated list of the mosses known to occur in Haiti, in all 261 species. Since that time I have discovered nine species new to the flora, most of them collected by Henry A. Imshaug and C. M. Wetmore in the D6partement de l'Ouest in July, 1958. The specimens cited below are in the herbarium of the National Museum of Canada. Leucobryum crispum C. Miill. On tree in ravine, northwest of For~t des Pins, Imshaug 22950. Widely distributed in the West Indies, northern South America, and Costa Rica. Encalypta vulgaris Hedw. On soil and limestone in burned-over pine forest, ca 8,800 ft, near summit of Pic La Selle, Imshaug 22999, Wetmore 1 National Museum of Canada, Ottawa, Ontario.

Greenland; arctic and western North America; Europe, Asia, North Africa, New Zealand. Leptodontium excelsum ( Sull.) Britt. On bark in burned-over forest, ca 8,800 ft, near summit of Pic La Selle, Wetmore 3087.-Virginia, North Carolina, Tennessee, Georgia; Mexico and Guatemala; Haiti. Although somewhat more robust than any North American specimens seen, these plants compare well in all structural details with authentic material and are also similar in having many leaves radiculose at their tips. Barbula purpuripes C. Miill. On clay of roadbank in open pine forest, ca 5,300 ft, between Fordt des Pins and Savane Zombie, Imshaug 2281.Previously known only from Jamaica, this species is related to the widespread B. cruegeri Sond. ex C. Miill. but has rather well differentiated, somewhat sheathing perichaetial leaves. Leptobryum pyriforme (Hedw.) Schimp. On soil in open, burned-over pine forest, ca 8,800 ft, near summit of Pic La Selle, Imshaug 22966.Greenland to Alaska and southward to the Gulf of Mexico and Arizona; Mexico to South America; Haiti; Europe and Asia; New Zealand. Bryum sawyeri Ren. & Card. Chardonette, Arrondissement de J6r6mie, 2,000 m, Bartlett 17627.-This specimen was named B. capillare Hedw. by A. LeRoy Andrews and reported as such (Crum & Steere 1958). It is very similar to B. capillare v. flaccidum (Brid.) B.S.CG., which is distributed almost all over the world and also occurs in Haiti. It also has axillary brood filaments, but it is easily distinguished by its firmer, less contorted leaves with broader tips. I have seen specimens from Florida, Louisiana, Cuba, and Haiti. Brachymenium speciosum (Hook. f. & Wils.) Steere. On branch in mist forest, 5,800-5,900 ft, summit of small peak at N end of Fort Venezuela, Ecuador, and Peru. Macrocoma hymenostomum (Mont.) Grout. On branch of shrub in open, burned-over pine forest, ca 8,800 ft, near summit of Pic La Selle, Imshaug 22961. North Carolina and Georgia; Mexico; Central America; Jamaica and Haiti; northern South America. Hookeriopsis falcata (Hook.) Jaeg. In mist forest, 5,800-5,900 ft, summit of small peak at N end of ridge above Fort northern South America.
