Cyanea acuminata (Gaud.) Hillebr. variety calycina Hosaka, new variety (fig. 2).

FIGURE 2. — a, Cyanea acuminata variety calycina, b, Cyanea acuminata, calyx.

Plant stricta 1-1.5 metra alta, labis calycis 4-5 mm. longis, corolla subpuberula, columna staminea glabra.

Plant erect with simple stem, 1-1.5 m. tall; leaves broad-oblong, acuminate at both ends, glabrous above, sparsely puberulous below; peduncles sparsely puberulous; calyx lobes 4-5 mm. long, lance-acuminate; corolla faintly puberulous; staminal column glabrous.

Oahu, Koolau Range, Waipio, Kipapa Gulch, altitude 1,700 feet along stream bed, August 7, 1933, E. Y. Hosaka 1185 (type in Bishop Museum).

This variety closely resembles Cyanea acuminata (Gaud.) Hillebr. but differs in having glabrous upper leaf surface, calyx lobes 4-5 mm. long, corolla faintly puberulous, staminal column glabrous. Cyanea acuminata has puberulous upper surface of leaf, calyx lobes 2 mm. long, corolla conspicuously puberulous, staminal column puberulous.

Cyanea Grimesiana Gaud. variety Munroi Hosaka, new variety.

Labis calycis 10-13 mm. longis.

Plant simple to branching, 1-3 m. tall; leaves 30-65 cm. long, 15-25 cm. wide, laciniate; calyx tube 7-10 mm. long, cylindrical, glabrous, lobes 10-13 mm. long, 4-6 mm. wide, broadly lanceolate; corolla (measured along curve) 4.5-5.5 cm. long, about 5 mm. wide, curved, glabrous; anther hirsute at base.

Lanai: Mts. E. end, June 1913, C. N. Forbes 266L.; August 23, 1919, G. C. Munro 673; Mahana, August 23, 1919, G. C. Munro 276; Ravine in Mt., moist woods, September 22, 1916, A. S. Hitchcock 14703; Kaiholena, November 3, 1913, G. C. Munro 166 (type in Bishop Museum).

This new variety closely resembles Cyanea Grimesiana Gaud. variety mauiensis Rock, but differs from it in having calyx lobes 10-13 mm. long, whereas variety mauiensis has calyx lobes 24-36 mm. long.

Rock [B.P.Bishop Mus., Mem. 7(2):251,1919] cites Hitchcock's specimen no. 14703 under variety mauiensis and says that this variety had not been reported previously from Lanai. Hitchcock's specimen is distinctly different from the type of variety mauiensis and is similar to the new variety Munroi, known only from the island of Lanai.

This variety is named for Mr. George C. Munro who has made the largest collection of Lanai plants during his long residence on the island.
