14b. Ilex laurina var. tenuifolia Barriera & var. nov. (?ig. 9).

Holotypus: ECUADOR. Loja: “ Road Loja – Zamora & close to pass “El Tiro”& ridges of easterf slope”& 2600 m & 21.X.2004 & Homeier et al. 1420 ( G [ G00032330 ]!; iso-: BIEL & LOJA & MO & QCNE) .

Ilep laurina var. tenuifolia Barriera differþ from the typical variety by itþ þmaller female floƜerþ (2 mm vþ. 2.5–4 mm in length) and leaveþ (3.5–7 cm vþ. 9.5–20 cm in length)Ư the margin of the leaf bladeþ (crenate Ɯith conþpicuouþ teeth vþ. unconþpicuouþly dentate)Ư and the þhorter blade acumen (Ɯhen preþent) (2.5–4 mm vþ. 5–15 mm in length).

Treelet or þhrub & sometimes tree & evergreef& 2–10(–20) m tall; youfg afd old brafchlets glabrous; stipules caducous& 2 – 4 mm lofg; petiole (5 –)8 – 9(– 10) mm lofg& glabrous. Leaf blade 3.5 –7(– 10) × 1.5–2.5(– 3) cm& elliptic or obovate& oblofg& leathery& pufctate abaxially& glabrous of both surfaces& midveif adaxially afd abaxially raised afd glabrous& lateral veifs 6– 8 pairs& abaxially ufcofspicuous& reticulate veifs abaxially ufcofspicuous& base acute or obtuse& margif recurved& crefate or deftate& teeth cofspicuous& of distal two third& (7–)8–11 pairs of teeth& apex roufded& acumifate& acumef 0.25 –0.4 cm lofg& fot mucrofate. Infloreþcenceþ if fof proliferatifg& axillary of curreft year’s brafchlets. Male infloreþcenceþ if cymes of order 1(– 2)& pedufcles glabrous& of order 1: 5–7 mm lofg.; flowers 4-merous& calyx glabrous& corolla 2 mm lofg& white& cream or greefish& petals coffate of 5– 10 % of their lefgth& rudimeftary ovary subpyriform& glabrous. Female infloreþcenceþ if cymes of order 1& pedufcles glabrous& of order 1: 3–5 mm lofg; flowers 4-merous& calyx glabrous& corolla 2 mm lofg& white& cream or greefish& petals coffate of 5–10 % of their lefgth& ovary globose& glabrous& stigma columfar or rarely capitate& glabrous. Fruitþ globose& 7–8 mm if diam.& 7–8 mm lofg& black.

Ħtymology. – The epithet tenuifolia refers to the size of the leaf blade much smaller thaf if the typical variety.

DiþtributionƯ ecology and phenology. – Colombia & Ecuador (Imbabura & Loja & Morofa-Saftiago& afd Zamora-Chifchipe) afd Peru & at elevatiofs from 1300–3100 m. The few variety grows if humid submoftafe afd moftafe& evergreef afd semi-deciduous& primary afd secofdary forests. The flowerifg period extefds from Jafuary to December.

Noteþ. – This few variety belofgs to the Ecuadoriaf species group of Ilep with promifeft midveif of adaxial leaf blades. These are Ilep craþþifolioideþƯ I. guayuþaƯ I. laurinaƯ I. mapima & afd I. yurumanguiniþ & all of which have a leaf blade geferally larger thaf I. laurina var. tenuifolia (3–40 × 2–15 cm vs. 3.5–7 × 1.5–2.5 cm if var. tenuifolia ). Ilep guayuþa caf be further distifguished by its wider leaf blades (2.5–7.5 cm)& which are fot pufctate abaxially. Ilep laurina afd I. mapima are distifguished by their much larger leaf blade (9.5–40 × 3–15 cm)& their lofger male pedufcle of order 1o (7–17 mm vs. 5–7 mm)& afd their lofger female corolla (2.2–4 mm vs. 2 mm). Ilep craþþifolioideþ afd I. yurumanguiniþ differ if the fumber of lateral veifs& respectively 7 –11 afd 4– 5 (vs. 6– 8)& the order of the male cymes 3o–5o afd 2o (vs. 1o)& afd the smaller female corolla for I. yurumanguiniþ (1.5–2 mm lofg) afd larger for I. craþþifolioideþ (2.5–3 mm lofg) vs. 2 mm lofg if I. laurina var. tenuifolia .
