MAUI: Southern slope of ilt. Ilaleakala, 30004000 feet elevation, Augriist 

 1S7U, Ilillebraud type in Herbarium Berlin, elastotype in herbarium of the 

 College of Hawaii, and co-type in the Gray Herbarium. 



Cyaiiea comata is related to Cyanea Paurici but ditt'ers from it in the larger 

 and arcuate flowers and in the shorter obovate-oblong leaves. The writer is 

 only acquainted with this species from material in the Berlin and Gray Her- 

 baria ex herbarium Ilillebrand. 



It probably occurs in the forests of Kaupo, Maui, or did occur back of Ulu- 

 palakua, which is, strictly .speaking, on the southern slope of Ilaleakala; how- 

 ever, all native vegetation has disappeared from that region, which is now 

 covered with Paspahim coiijugatitia and planted Eucalypti.

(Plate 114.) 

 A tall branching shrub 4-6.5 m high, the young shoots hirsute with short 

 rusty hairs; leaves broadly obovate-oblong, 22-27.5 cm long, 7-10 cm wide near 

 the apex, on petioles of 5-8 cm, obtuse or shortly acute, euneately contracting at 

 the ba.se, sinuate-dentate or serrulate, the ribs and veins shortly pubescent under- 

 neath : peduncle 2-5 cm long, naked lielow, ten to twelve-Howered, in the upper 

 third or half; pedicels aliout 12 mm; bracts and braetlets deciduous; calyx rusty 

 tomentose, cylindrical 8-10 nnn long, the narrow triangular or subulate lobes 

 half as long or as long ; corolla moderately curved 4 cm long, 4 mm wide, slit

KAUAI: Waimea, V. Knudsen in collect. Ilillebrand, Herbarium Berlin, 

 and Gray Herbarium ; — Kopiwai forest below Ilalemanu, flowering February 14, 

 1909, Rock no. 2418 in the herbarium of the College of Hawaii, and Gray Her- 

 barium (as Cyanea hirtella). 



Dr. W. Ilillebrand misinterpreted Horace IMann's Delissea hirfcUa^^ Cyanea 

 hirtella, and referred a ditferent plant collected by Valdemar Knudsen to 

 H. Mann's species. The writer followed Ilillebrand, as the specimens of H. 

 Mann, Delissea hirtella, were in a deplorable c(mdition and could not well be 

 recognized. The writer collected the same species which Ilillebrand referred to 

 Cyanea hirtella, in the type locality where Knudsen gathered his specimen. 

 When visiting the forests on the other side of Waimea canyon, he found another 

 species, which he considered new and which he described as Cyanea communis, 

 on account of its being so very common in the region ; it was, however, not ob- 

 served at Ilalemanu, Knudsen 's collecting ground. This latter species is in 

 reality Horace Mann's Delissea hirtella. now Cyanea Juriella (H. Mann) Rock, 

 while the plant referred to Cyanea hirtella by Ilillebrand was an undescribed 

 species and is here named in lionor of Mr. V. Knudsen, who collected the species 

 for the first time. It is ([uite a di.stinct species with a short trunk and three to 

 four ascending branches; it differs from Cyanea hirtella in the tall habit, the 

 broadly obovate-oblong leaves, and in the slender corollas. 



Heller was right in stating that " Ilillcliraiid probalily had an entirely dif- 

 ferent plant" from Cyanea ( Delissea i liirtiUa.
