MOLOKAI : In the deep ravine of Wailianau, in shade aking streambed, 

 elevation 3000 feet, tlowering August 13, 1918, L. jM. Dunbar type no. 13119 in 

 herbarium of the College of Hawaii. 



This interesting species conies close to Cijcuua sdhiinicra llillclii'., but differs 

 from it in the smaller thinner leaves and the spineless character of the plant; 

 the pedicels are longer, and the staminal column glabrous. 



The species is somewhat variable, especially the color of the tiower. which is 

 sometimes not pure white but has lilac to bluish stripes; the ape.x: of the corolla 

 is then warty instead of ridged. The species is named in honor of Mrs. L. M. 

 Dunbar, who collected the type material. The writer collected sterile specimens 

 of this species during the month of ^lay in the type locality.

(Plates 47, 1.50.) 



A branching shrub 1.3-2 m high, sparsely aculeate: leaves obovate-oblong in 

 outline, 32-1-2 cm long. 10-25 em wide, on prickly petioles of 7.5-10 cm. deeply 

 cut into connected segments or pinuatisect to the rhachis with or without inter- 

 vening lobules, or pinnate, the segments contracted at the base, almost stipitate, 

 gradually or suddenly decreasing in size toward the base, all bluntly acuminate, 

 entire or sinuate, membranous, glabrate sparsely murieate on ribs and nerves; 

 peduncles 5 em long, slender, naked or distantly bracteate below, 10-15-rtowered 

 near the apex; pedicels 8-12 mm; bracts setaceous. 3 mm. but sometimes folia- 

 ceous; calyx glaliroiis. the tube obconical, 4-6 nun, its lobes as long or shorter, 

 linear lanceolate, acute; corolla semierect, 38 mm or more in length, sparingly

MAUI: AA^aihee Valley, ilaun and Brigliam no. JiHl in herliarium Cornell 

 T"ni versify and Gray Herbarium; — Kaanapali, August 1870 (flowering speci- 

 men), Hillebrand in Herbarium Berlin, and Gray Herbarium; — Waihee Valley, 

 tlowerbuds, September 5, 1918, Rock & Hashimoto, no. 13134 in herbarium College 

 of Hawaii. 



According to Hillebrand the leaves in specimens from Kaanapali are pin- 

 natisect, and those from Waihee and Waiehu pinnate. The jdant resembles 

 greatly C. Gn'nwsiana outwardly, luit is related to ('. sohnidcdi and belongs to 

 the group of ('. .icnbra Hillelir. 



The writer has collected this species in the type locality and has examined 

 ilann's type no. 464 in the herbarium of Cornell University. Hillebrand 's 

 specimen in the Gray Herbarium has nnich larger leaves and longer pinnae than 

 those in the Berlin Herbarium. 



The jnurication of the corolla is better visible when the flowers are not yet 

 oi^en. In II. Alaun's type the murication of the corolla is less pronounced than 

 in Hillebrand 's plant, on account of the open, mature flowers.
