Cyanea Wailauensis Rock Coll. ?Iaw. Publ. Bull. 2:43. 1913. 



(Plate 87.) 

 The plant erect, 1.5 m hi^h, not branching', stem tleshy. but woody at the 

 base, unarmed and covered in its upper portion with leaf-scars, with a crown of 

 leaves at the apex; leaves chartaceous when dry, somewhat tleshy when fresh, 

 pale green, dull and glabrous above, with prominent veins and imj)ressed mid- 

 rib, obovate-oblong, cuspidate to acute at the apex, gradually narrowing at the 

 base, somewhat wavy and eroso-dentate at the margin, puberulous underneath, 

 30-4:0 cm long, 10-18 cm wide on petioles of 4-8 cm, young leaves hispid ; racemes 

 arranged along the upper jiortion of the stem, somewhat similar to Cyanea acu- 

 nihtata. peduncle thick about 4 cm long, densely studded almost from the base 

 with large close knobby sears of a pale color. 6-8 tiowered at the ajiex. peduncle 

 hirsute as are the linear bracts; pedicels 1 cm long, hispid; calyx hisitidulous to 

 hirsute, the ovarian ]iortiou 10 mm, the linear oblong lobes 15-18 mm. free to 

 the base: corolla of a dirty wliite, the tube 22-25 mm, hirsute as are the unequal 

 lobes, the dorsal slit extending 2/5 its length; staminal column dark purple, 

 glabrous, the lower anthers bearded, stigma surrounded at its base by a tuft of 

 small, white hairs; fruit unknown; but calyx-lobes persistent with fruit as is 

 evidenced from very young fruits. 



MOLOKAI: Valley of Wailau, elevation 1000 feet, ah)ng streambed at the 

 head of the valley in company with ('i/anea Griinesiana. flowering April 1910, 

 Rock no. 8812 type in the herbarium of the College of Hawaii and cotype in 

 Gray Herbarium; — ^Majiulehu, ilay 1915, Rock in herl)arium College of Ha- 

 waii; — Pukoo, llr. Conradt's place, rain forest flowering October 8, 1916, A. S. 

 Hitchcock no. 15008 in IT. S. National Herbarium and part in herbarium 

 College of Hawaii: — perhaps also a plant from the same locality, A. S. Hitch- 

 cock no. 1507.S in U. S. National Herbarium. 



The plant differs from ('ijaiua xolcnocahjr. to which it is closely related, 

 luainly in the thick peduncle with closely set knobby scars, the very short M-hite 

 flowei's which are almost hidden in the calyx. The species is single-stemmed 

 and unarmed. 



Hitchcock's specimens have not the knobby peduncles as in the type; perhaps 

 it is only a very variable species and identical with Cyanea solenocaly.r. 



Cyanea procera llillebr. M.ira Haw. Isl. 262. 1888. 



(I 'late s,s. ) 

 Trunk and leaves as in Cyaiica arhorca, the leaves broader ll)-15 cm, closely 

 denticulate, pubescent undei-neath ; peduncle short, thick and fleshy, 2.5-3.75 cm 

 long with many (10-20) flowers near the apex, the pedicels 6-10 mm, bracteolate 

 at the base; bracts 10 mm, bracteoles 4 mm; calycine tube glabrous, cylindrical, 

 10-14 mm in length, with triangular lobes of 3-4 mm; corolla (undeveloped) 

 glalirous, over 6 mm broad, bluish below, greenish-yellow above, thick fleshy. 



ilOLOKAI: Kamolo, 2000 feet elevation, Hillebrand; type in Herbarium 

 Berlin, and co-type in the Gray Herbarium. 



Nearly related to Cijanca arborea (Mann) Hillebr. In both the trunk has a 

 thick woody zone which includes a narrow cavity septate by niuuerous paper\- 

 diaphragms. 



To the writer the species is only known from the material in the Berlin 

 Herbarium : co-type in Gray Herbarium, labeled Dellssea procera sp. n. iMolokai, 

 Kamolo.
