General Information
Psychotria hobdyi, a tree in the coffee family (Rubiaceae), can reach up to 8 m (26 ft) tall and has grayish brown branches. Leaves are membranous to leathery, oblanceolate (rounded apex and tapering base), and pink or rose-colored on the lower surface. The lower leaf surface is glabrous to somewhat pubescent with small or absent domatia. Flowers are functionally unisexual.» Range Information

Habitat Requirements
Psychotria hobdyi typically occurs in lowland Acacia koa (koa) Metrosideros polymorpha (ohia) diverse mesic forest in the lowland mesic ecosystem at elevations between 1,700 and 2,700 fet (520 and 825 m). Associated native plant species include Alphitonia ponderosa (kauila), Alyxia stellata (maile), Antidesma platyphyllum (hame), Bobea brevipes (ahakea lau lii), Carex meyenii, Charpentiera elliptica (papala), Cheirodendron trigynum (olapa), Chrysodracon spp. (hala pepe), Diospyros sandwicensis (lama), Diplazium sandwichianum (hoio), Dodonaea viscosa (aalii), Doodia kunthiana (okupukupu), Dryopteris unidentata (akole), Elaeocarpus bifidus (kalia), Euphorbia spp. (akoko), Gahnia beecheyi, Isodendrion laurifolium (aupaka), Kadua affinis (manono), Lepisorus thunbergianus (pakahakaha), Leptecophylla tamaeiameiae (pukiawe), Microlepia speluncae, Nestigis sandwicensis (olopua), Peperomia spp. (ala ala wai nui), Perrottetia sandwicensis (olomea), Peucedanum sandwicense (makou), Pisonia spp. (papala kepau), Pittosporum kauaiense (hoawa), Planchonella sandwicensis (alaa), Polyscias spp. (ohe), Pritchardia minor (loulu), Psychotria spp. (kopiko), Psydrax odorata (alahee), Remya kauaiensis, Scaevola procera (naupaka kuahiwi), Smilax melastomifolia (hoi kuahiwi),Streblus pendulinus (aiai), Vaccinium dentatum (ohelo), Syzygium sandwicensis (ohia ha), and Xylosma hawaiiense (maua).
Movement / Home Range
Historically, Psychotria hobdyi occurred in Mahanaloa Valley on Kauai. Currently, it occurs in Kawaiula Valley, Kuia Valley, Mahanaloa Valley, Paaiki Valley, Poopooiki Valley, and Kalalau Valley.
Reproductive Strategy
Psychotria grandiflora and P. hobdyi were the only two Hawaiian Psychotria taxa that exhibited floral monomorphy (two sexes are phenotypically indistinguishable). The restricted distribution of the P. grandiflora and P. hobdyi clade to the oldest part of the oldest island in the Hawaiian chain provides two equally likely hypotheses of breeding system evolution. One implies ancestral floral monomorphy and two transitions to gynodioecy (male sterile individuals (i.e., females) coexist with hermaphroditic individuals in populations) and the other assumes ancestral gynodioecy with a single reversal to homomorphy (all flowers have exactly the same structure). Nepokroeff et al. (2003) investigated the systematic and biogeographical relationships within the Hawaiian Psychotria (Rubiaceae) using ribosaomal DNA. Phylogenetic analyses strongly suggest that the Hawaiian Psychotria are monophyletic and the result of a single introduction to the Hawaiian islands with a pattern of colonization from oldest to youngest islands. Additionally, a much higher incidence of intraisland versus interisland speciation was inferred. Its flowering cycles, pollination vectors, seed dispersal agents, longevity, specific environmental requirements, and limiting factors are unknown.
Other
This species is distinguishable from P. grandiflora, to which it is closely related, by the nature of the inflorescence and leaves. The inflorescence of P. hobdyi has a very small peduncle compared to that of P. grandiflora, and the leaves are membranous and much larger than those usually found in the latter. Psychotria hobdyi was first described by St. John (1975) as Psychotria rosacea from a specimen collected by Hobdy in 1970 at Mahanaloa Valley on Kauai. The species was later renamed by Sohmer (1977) as Psychotria hobdyi in reference to the collector.
