Bcccari and Rock — PritcJiardia. 63 



calyx; anthers sagittate; ovary turbinate, conically narrowing into a sulcate 

 style. Fruit subspherical, glossy, yellowish to grayish brown when mature, 22 mm. 

 long, 20 mm. broad, somewhat truncate at the base, with one or two more or less 

 pronounced ridges; mesocarp deep black, nearly 3 mm. in diameter, grumose and 

 accompanied by several strong stiff fibers ; endocarp hard woody 0.5 mm. in diam. 

 Seed ovoid, the apex slightly pointed with wart-like protuberance, otherwise 

 rounded, yellowish brown in color and marked with paler streaks, about 13 mm. 

 long, 10 to II mm. in diameter. Hilum large, oblong; embryo not far from the 

 upper raphe margin. Fniitiug perianth missing. 



Habitat. — Molokai, leeward side, at an elevation of 2000 ft. above Kamalo 

 and near or at Puakoolau, in a dry gulch, associated with Xantho.vvliiui uiaiiicnse, 

 Dodonaea stenoptera. D. viscosa, Sida, Maha sandivicensis, Dracaena aiirea, etc. 



Observations. — A very remarkable species, easily distinguished by the very 

 small panicles which are densely covered with dirty grayish brown hair and by 

 the small subglobose fruits which resemble those of Pritchardia rcniota Becc. 

 The leaves of Pritchardia Miinroii Rock are covered in the lower portion, especially 

 on the costae of the under surface, with large and broad translucent paleae which 

 are larger than in any other species known. It is the onh^ species with globose 

 to subglobose fruits and densely woolly panicles ; the fruits alone resemble those 

 of the PritcJiardia reinota, or Pr. atfinis. The species is named for Mr. James 

 Munro, manager of the Molokai Ranch, who is an ardent and keen supporter of 

 the natural sciences, and to whom the writer is indebted for many kindnesses. 

 The species was discovered Februarj^ 20, 1920, Mr. Munro and Mrs. L. M. Dunbar 

 being present: Rock Xo. 17342, type in the College of Hawaii Herbarium. The 

 species has also been under cultivation on Molokai at the home of Mr. O. Meyer 

 at Kalae; here a plant from which specimens were collected has been growing 

 for many years, but has a trunk only about 2 feet in height: Rock No. 17341 in 

 the College of Hawaii Herbarium.

(Plates X\;, A; XX, D) 



Description. — One of the largest. Stem 10-12 m. high and 50 cm. (or 

 less ?) in diam. Leaf blade 1.30 m. long from the ligula to apex, and parted to 

 above the middle into about 60 segments; the lower surface is entirely clothed 

 with a light yellow, nearly golden adherent tomentum, composed of hyaline, scale- 

 like, much fringed and felt'ed lepidia; the segments are very deeply parted into 

 two very long laciniae which taper very gradually to filiform apices ; the central 

 segments are 5-6 cm. broad at their disjunction places. Petioles stout and broad 

 (4.5 -q cm. broad at apex), covered on the lower surface with a fulvous, more or 

 less removable tomentum, which extends to the dorsum of the costae; ligula 

 short, crescent like, distinctly apiculate. Spadices elongate, composed of an ovate 

 thyrsoid panicle, about 20 cm. long, borne on a very long terete peduncular part,
