NOTES ON NEW AND NOTEWORTHY PLANTS. CLVI Harold N. lloldenke LANTRNA PASTAZENSIS Hold . , sp. nov. Frutex, ramulls obtuse tetragonis sulcatls antrorse adpresso-strigulosis; follls decussato-oppositis breviter petiolatis; petiolls dense adpresso-strigulosis; laminis foliorxim tenuiter membranaceis late ovatis usque ad 18 cm. longis 10 cm. latis apicaliter abrupte subacurainatis marginaliter antrorse-serratis basaliter truncatis vel in petiolura coarctatis utrinque minu-tissime puberulis; inflorescentiis axillaribus solltarlis; pedun-culo elongate petiolum longe excedente ca. 8 cm. longo denslus-cule adpresso-striguloso; capitulo parvo ca. 1 cm. longo latoque; bracteis magnis late ovatis vel elliptico-ovatis ca. 8 mm. latis 10 mm. longis apicaliter abrupte acuminatis vel subcaudatis utrin-que adpresso-puberulis. A shrub, 0.4 — 0.7 m. tall; branchlets apparently slender, light or the younger parts darkening in drying, very medullose, obtusely tetragonal with rounded angles, deeply canaliculate, densely and antrorsely appressed-strigulose throughout, more densely so at the nodes; principal internodes apparently much elongate on floriferous branchlets, to 10 cm. long; leaves decus-sate-opposite; petioles relatively short, about 1 cm. long, dense-ly and antrorsely appressed-strigulose, apically merging into the leaf-base; leaf-blades thinly membranous, bright-green on both surfaces, not blackening in drying, broadly ovate, 12 — 18 cm. long, 7 — 10 cm. wide, apically rather abruptly short-acuminate, marginally serrate with rather uniform, antrorse, broad-based, a-cute or subacute teeth to below the widest part from the very a-pex, the teeth somewhat more appressed as the leaf-apex is ap-proached, basally truncate and usually extending into the petiole, very minutely puberulent on both surfaces under a handlens; in-florescence axillary, solitary, surpassing the subtending petiole but not surpassing the leaf-blade; peduncles slender, much elon-gate, about 8 cm. long, rather densely and antrorsely appressed-strigulose throughout; heads relatively small and relatively few-flowered, about 1 cm. long and wide; bracts rather foliose, large, broadly ovate or elliptic-ovate, about 10 mm. long and 8 mm. v^ide, often undate or somewhat conduplicate, apically abruptly acumin-ate to subcaudate, minutely appressed-puberulent on both surfaces; corolla hypocraterlform, pale reddish-violet, with a yellow center. The type of this species was collected by B. L«5jtnant and U. Molau (no. 13421) in "fields, hedgerows, and loans [ sic ; =lawns?] with small ditches" within the military camp at Montalvo, in Pastaza province, Ecuador, at about 250 m. altitude, between May 17 and 22, 1979, and is deposited in the Herbarium Jutlandicum at Aarhus University. 468 I
