schiedener Hinsicht unzureichend ist, so gebe ich im folgenden eine ein- 

 gehendere Neubeschreibung dieser interessanten Varietät. 



Discopodium penninervium Höchst, in Flora 1844, 22 var. Holstii

 Solanum Albej'si Damm. mscr. in herb. Berol. — Fruticosum, i — 2 m 

 altum; rami superiores er. 3 — 6 mm crassi, rimosi-angulati, angulis rotun- 

 datis, in statu novello pilis patentibus pluricellularibus acutis tenuimembra- 

 naceis satis longis sordide ochracei-albidis vel flavidi-albidis densis tomen- 

 tosi, serius it ve calvescentes, cortice viridi-fuscescente levi obtecti; inter- 

 nodia in partibus inferioribus longiora, er. 4,5 cm longa, in partibus su- 

 perioribus breviora, er. i— 3 cm longa; folia inferiora solitaria, superiora 

 saepe geminata inaequaha; petioli in foliis majoribus inferioribus er. 2 — 4,5 cm 

 longi, in foliis superioribus 1 — 2,5 cm longi, eodem indumento quo rami 

 novelli induti; laminae late lanceolatae, utrinque sensim angustatae, basi 

 in petiolum superne alatum abeuntes, apice acutae vel acuminatae, margine 

 integro vel undulati-repando, inferiores er. 14,5:7 — 21,5:8,5 cm^ superiores 

 majores er. 12:5 — 15:6cm, minores er. 9:4 cm, supra in statu novello 

 non jam satis evoluto pilis simplicibus pallide ochracei-albidis tenuiter ara- 

 neosi-tomentosulae, mox tomento fere evanido glabrescentes, sordide virides, 

 subtus tomento ochracei-albido denso e pilis longis simplicibus pluricellu- 

 laribus tenui-membranaceis dense araneoso obtectae; tomentum secundum 

 venam mediam venasque laterales primarias densissimum; vena media et 

 venae laterales primariae in utroque latere er. 12 subparallelae curvatim 

 ascendentes et venae later. secund. illas reticulatim conjungentes subtus 

 manifeste prominentes; inflorescentiae sessiles in axillis foliorum, 6 — 10- 

 florae; pedicelli 10 — 13 mm longi; calyx cupulatus, er. 4 mm longus, 6 mm 

 diam., fere truncatus, indistincte 5- lobus, lobis parum prominentibus ob- 

 tusiusculis, extus sicut pedicelli pilis simplicibus pluricellularibus acutis 

 (brevioribus quam in ramis novellis et in laminae superficie inferiore) ara- 

 neose puberulus; corolla campanulata, er. 9 — 10 mm longa, 8 mm diam._, 

 in parte apicali in lobos 5 lanceolatos acutos er. 3: 1 — 1,5 mm primo rectos 

 tandem recurvatos partita, in parte basilari glabra, supra medium extus 

 et in lobis quoque intus pilis subochraceis densis brevioribus obtecta; fila- 

 menta glabra, corollae fere tota longiludine (er. 1,5 — 2 mm) adnata, quam 

 ob rem antherae sessiles in media fere altitudine tubi; antherae breviter 

 ovoidei-ellipsoideae, er. 2:1 mm, basi cordatae; ovarium glabrum^ sub- 

 globosum; Stylus rectus, brevis, er. 3 mm longus, glaber; stigma crassum, 

 subglobosum, depressum; calyx in statu fructifero non ampliatus; bacca 

 globosa rubra (sec. cl. Albers, maturam non vidi).
