General Information

Shrubs or trees, deciduous or evergreen, often from underground woody burl or producing thickened horizontal underground rhizomes. Buds flattened, conical or ovoid, usually with 2 large imbricate glabrous scales. Leaves spirally arranged, petiolate; leaf blade entire [toothed in United States]. Inflorescences axillary, racemose. Flowers [4- or]5[–8]-merous. Calyx with variously estivated lobes, usually valvate in bud. Corolla white [to red], tubular or urceolate; lobes short. Filaments flattened, geniculate, with or without 1 pair of spurs at anther-filament junction; anthers dehiscing by introrse-terminal elliptic pores. Ovary superior, with many ovules per locule; stigma truncate. Capsule loculicidal, with pale ± thickened sutures sometimes separating from valves in dehiscence. Seeds oblong-ovoid or spindle-shaped to shortly linear, minute, ends often truncated.

    Xolisma Raf.

    Por J.L. Luteyn.

    Arbustos o árboles, frecuentemente brotando de nudos subterráneos, u ocasionalmente formando matorrales con rizomas subterráneos. Hojas alternas, perennes o deciduas, pecioladas, la nervadura broquidódroma a eucamptódroma, los márgenes enteros a irregular e inconspicuamente dentados, fuertemente dentados, o serrulados. Inflorescencias axilares, racemosas, fasciculadas, o paniculadas; brácteas florales 1, pequeñas a grandes; pedicelos articulados con el cáliz; bractéolas 2, frecuentemente caducas, en la base de los pedicelos o cerca de ella. Flores 4-7(-0 8)-meras, generalmente fragante, la estivación valvada a imbricada; cáliz generalmente persistente en el fruto; corola simpétala, cilíndrica a urceolada, campanulada, o cilíndrica con bases hinchadas; estambres 8-14(-16), iguales, incluidos; filamentos distintos, iguales, geniculados, papilosos o con pelos largos, unicelulares, con o sin un par de apéndices cortos espoloniformes por debajo de la unión antera-filamento; anteras diminutamente papilosas, sin aristas apicales, dehiscentes por poros elípticos, introrso-terminales, siempre con tejido de desintegración blanco por detrás de cada lobo extendiéndose a lo largo del ápice de los filamentos y a lo largo del borde superior de los espolones, cuando presentes; polen sin hilos de viscina; disco nectarífero formado de un agrandamiento de la base de la pared del ovario, variadamente desarrollado y lobado; ovario súpero; estilo columnar, por lo general, cuando menos ligeramente hinchado cerca de la base, impreso hacia el ápice del ovario, incluido a ligeramente exerto, el estigma truncado a capitado. Frutos en cápsulas erectas, con suturas pálidas engrosadas, generalmente separándose de las valvas durante la dehiscencia; semillas pequeñas, los extremos a veces truncados o con extensiones o caudas estériles. 2 n =24. 36 spp. (52 taxa).

    Shrubs or trees, (sometimes with woody burl, resprouting after fire). Stems erect to arching; twigs hairy, sometimes glabrescent (sometimes also lepidote). Leaves deciduous or persistent; blade elliptic, obovate, or ovate, membranous to coriaceous, margins entire, undulate, or serrulate [irregularly serrate], plane or revolute, surfaces multicellular, peltate-scaled or short-stalked stipitate-glandular-hairy, often unicellular-hairy on major veins or abaxial surface; venation brochidodromous (or reticulodromous). Inflorescences axillary fascicles, panicles, or racemes, (2-)5-8(-12)-flowered, sometimes flowers solitary, (produced just before flowering). Pedicels: bracteoles 2, at or near base. Flowers: sepals usually [4-]5[-8], slightly connate, ovate-deltate to lanceolate; petals usually [4-]5[-8], connate nearly their entire lengths, white to red, corolla cylindric to urceolate, lobes much shorter than tube, (sparsely stipitate-glandular-hairy or peltate-scaled); stamens usually [8-]10[-16], included; filaments geniculate, flattened, roughened or hairy, with or without spurs; anthers without awns, dehiscent by elliptic pores; pistil usually [4-]5[-8]-carpellate; ovary [4-]5[-8]-locular; (style slightly longer than stamens); stigma capitate-truncate. Fruits capsular, globose to ovoid or ellipsoid, dry, (with [4-]5[-8] pale, decidedly thickened, whitish sutures). Seeds ca. 100-300, ellipsoidal, narrowly oblong, obovoid to angular-obovoid or narrowly conic, (sometimes tailed); testa cells elongate. x = 12.

    "Fls 5-merous; cal saucer-shaped to campanulate, deeply divided, the lobes valvate; cor globose to tubular or ovoid, the lobes short; stamens well included; filaments basally dilated, geniculate above; anthers ovate, dorsifixed, spurred but awnless, opening by 2 terminal pores; style columnar to fusiform; stigma truncate; capsule globose to truncate-ovoid, loculicidal, the sutures thickened and appearing as 5 rounded ribs; deciduous or evergreen shrubs with alternate, entire or minutely serrulate lvs; fls white to rose, on long pedicels in umbelliform lateral clusters that may be borne in the axils of the lvs or may be distributed along lfless branches to form a compound, racemiform to paniculiform infl. 35, N.
