摘要:

Gahnia gahniaeformis(Gaud.) Heller of Hawaii andG. affinis(Brongn.) Steud. of New Zealand have long been, and are still considered by the monographer BENL (1940), to be synonyms. They have constant, diagnostic differences in stature, and in structure of leaves, bracts, spikelet color, inner glumes, achene size, shape, color, and epidermal cells. The only reason for confusing the two seems to have been that on the holotype sheet ofG. affinisis a pocket which includes some achenes taken from the holotype ofG. gahniaeformis.Also the holotype sheet ofG. gahniaeformisfrom Hawaii bears a second old pocket marked by BRONGNIART « Lampocarya. N. Zeel. » containing spikelets and half of a sectioned achene from the holotype ofG. affinis.The achenes of both species were illustrated by BRONGNIART. It is clear that he left some achenes of each upon the holotype sheet of the other. No other evidence of overlap of characters is known. Hence,G. gahniaeformisis known only from the Hawaiian Islands, andG. afjinisis reestablished as a distinct species, restricted to New Zealand.

摘要:

Questa è la seconda parte della flora sinotticaPrima Flora Colombiana.Essa segue il medesimo modello della prima parte (Burseraceaein Webbia12: 375–441, 1957) ma per leMalpighiaceaele chiavi delle specie sono di tipo dicotonico. Corne nelleBurseraceaevengono dati i sinonimi, la distribuzione basata sulle raccolte, osservazioni tassonomiche, nomi vernacolari ed usi; vengono anche aggiunte considerazioni circa le proprietà narcotiche di alcune specie diMalpighiaceae(per esempioyagé, caapi).
