HAWAII : Forests of Puna in dense woods along the Kalapana road not far 

 from Pahoa, flowering September 3, 1917, Rock & Newell (type) no. 12S31 in the 

 herbarium of the College of Hawaii. 



This rather variable species is renuirkably like a ItiiUaiidia. The plant varies 

 considerably in the spinosity of the leaves, petioles and stems ; some of the speci- 

 mens almost approach Cyanca noU-inc-Uinyrrc Rock in spinosity, while others are 

 only muricate. The color of flowers is also variable, ranging from pale yellowish 

 white with deep purplish streaks to entire dark purple. In haltit it approaches 

 RoUandin lanccohtta. but actually seems to come close to Cijaiica iioU-)nc-tangere; 

 from the latter it differs in the long-petioled leaves, which are much larger, and 

 in the longer naked peduncles which are not spinose. The plant as a whole is 

 much larger in every way, the flowers are purple, as are the veins and midrib of 

 the leaves; the whole inflorescence is glabrous. Cyanca noli-ine-tangere is very 

 loosely foliate, while C. rdllaiidloides is simple-stemmed and has at its ape.x a 

 dense crown of leaves. It seems that its closest congener may be looked for in 

 Cyanca pInfyphyUa, and it is on that account that it is placed into this section, 

 rather than in section palmaeformcs. 



The plants grow in the wet forests of Puna, on Hawaii, a little explored dis- 

 trict and one of the most primitive regions on the island of Hawaii. A stalwart 

 Hawaiian gave the writer the native name Aku-aku for the species in question, of 

 which he said the leaves were cooked with meat and eaten like cabbage. The 

 name Akti alone is applied to Cyanca tritoniantha, to which our plant has no 

 resemblance. The species was collected in company with Brother Matthias 

 Newell of Ililo, an ardent naturalist.

"Size and habit of Cyanea solonacea Hillebr., the branches bristling with 

 thorns; leaves of young plants bipinnatisect, to the rhachis in the lower portion, 

 and covered with spines; those of the adult plant oblanceolate in outline 2-5-30 em

 depth which shorten to auricles at the base, on petioles of 3.75-5 cm, papilloso- 

 hispid on the upper, scabro-hispid on the lower face, thick chartaceous, with 

 prominent nerves, not aculeate; peduncle (with buds) 2.5 em long, floriferous at 

 the end ; calyx muricato-hispid, the lobes one-nerved, oblong, ol^tuse, apiculate,

Hillebrand evidently did not label his specimens with the flual name under 

 which he published his species, or tlie authorities of the Berlin Herbarium were 

 not at all careful in the distribution of the duplicates of his Hawaiian plants. 

 Hillebrand 's material should have been kept together, but as it is, his collection 

 is now scattered to the four winds; even types are missing, and Hillebrand 's 

 original labels have been discarded and replaced by Berlin Herbarium labels;
