Ipomoea tiliacea var. smithii Fosberg

Ipomoea tiliacea var. smithii Fosberg

Herba scandens foliis orbiculari-cordatis saepe grandi-dentatis vel lobatis longi petiolatis, cymis pedunculatis congestis, sepalis orbicularibus caudato-aristatis inaequalibus, corollis 4–5 cm longis limbo expanso.

Differs from var. merremioides in the usually larger, more orbicular, less long-acuminate, usually remotely coarsely dentate or at least somewhat irregularly margined, rarely lobed leaves, up to 10 × 12 cm, usually much smaller, pilose beneath on lower parts of main veins, petioles much longer; peduncles strong, 2–6 cm long, pedicels 3–5 in a crowded cyme or pseudo-umbel; sepals somewhat unequal, orbicular, gradually caudate-aristate, tending to be very sparsely pilose or long ciliate, corolla 4–5 cm long, white, or “pink-lavender” or “red-pink” with darker center.

The specimens cited below are not very uniform. The Tongan ones have larger leaves and the U. S. Exploring Expedition one has notably lobed leaves. The Tongan ones have colored flowers, the Fijian white; however, they seem to belong together. The U. S. Exploring Expedition collection shows that the plant is probably indigenous, at least not a recent arrival, in the Pacific Islands.

The variety is named for Professor A. C. Smith, collector of the type.

5. Annotations to the Hawaiian Flora

Over the past 35 years the senior author has published several series of miscellaneous notes, which either have dealt exclusively with Hawaiian plants (Fosberg, 1936, 1937, 1942, 1948, 1962, 1966b, 1969), or have contained some material on Hawaiian plants along with notes on other Pacific island groups (Fosberg, 1943, 1966a, 1968).

This is essentially a continuation of these observations on the flora of the Hawaiian Islands. Included are distributional records, field and herbarium observations, comments directing attention to items of interest to Hawaiian botany published in literature not primarily concerning Hawaii, and taxonomic and nomenclatural notes and keys to certain groups adventive in Hawaii. The genera included are Adiantum, Carex, Cyperus, Salicornia, Dianthus, Bocconia, Rubus, Crotalaria, Lotus, Polygala, Melochia, Waltheria, Frankenia, Dissotis, Thevetia, Heliotropium, Stenogyne, Solarium, Parentucellia, Tetranema, Plantago, and Hedyotis.

Since the greater part of this paper was written, Professor Harold St. John’s magnificent List and Summary of the Flowering Plants in the Hawaiian Islands (1973) has appeared. Certain of the new records appeared there, but since no details of occurrence are given it seems desirable to give these here, also, to provide verified references to the places of publication and certain subsequent papers of interest.
