species as Cyanea solanacea. The variety qucrcifolia still bears in his hand- 

 writing the name Cyanea armata sp. u. var .qucrcifolia. It is the variety querci- 

 folia of Cyanea solanacea from Ulupalakua, Maui. All four specimens are here 

 published ; the first is considered as the type, the second is a mature form of the 

 species. The type shows a young plant and a portion of a mature plant and 

 an inflorescence. Young plants of this species are densely spinose when young 

 but lose them when they become mature; the leaves in old plants also become less 

 lobed than in young plants. This accounts for the specimen represented on the 

 second plate being without spines and having sinuate leaves only. 



There is another specimen in IIillel)vand's herliariuni in Berlin, consisting of 

 three ditt'erent types of leaves: one very young one, almost bipiiniate; a large 

 pinnate one representing a leaf of a young plant and a subentire or notched 

 smaller leaf from a mature plant. These three leaves belong to Cyanea solanacea. 

 They are labeled in a heavy handwriting, "Jlolokai, ins. sandvic. W. Hillebrand, 

 1870."

(Plate Hfl.) 



Leaves laruer ST.o-.lO cm long, 7.75-15 cm wide, thicker scabrous on the upper, 

 hispid on the lower face, with prominent nerves, the lobes deeper and rounded, 

 cut to the rhaehis at the narrow base; calyx glabrous, the lobes 4 mm; corolla as 

 above, but glabrous; the staminal column and anthers pubescent; berry 16 mm.

 Herbarium Berlin; — Hamakua, Hillebrand, not in Herbarium Berlin. 



According to Hillebrand this variety attains the size of a .small tree fifteen 

 feet (five meters) high. The writer has not collected this variety and knows it 

 only from Hillebrand 's material in the Berlin Herbarium. At Ulupalakua the 

 plant has become extinct; there is not a vestige of forest left in that district. 

 The only remaining sif':n of a forest is here and there a tree of Pterotropia 

 dipyrcna; the rest is grazing land and planted Eucalyi)ti. 



From the description it would appear that this supposed variety is a distinct 

 species referable to the section palniaeformcs, but owing to the scanty material 

 the writer thought it best to follow Hillebrand.
