Ill. Syringa Sweginzowii Koehne et Lingelsheim nov. spec. 
(Originaldiagnose.) 
Ramuli griseo-vel fusco-brunnei, sparse lenticellati lenticellis orbi- 
culatis, glaberrimi. Gemmae c. 3 mm longae, ovato-conicae, fuscae, 
glabrae. Folia papyracea ambitu oblonga vel ovata, basi paullo attenuata, 
apice saepius abrupte caudato-acuminata, 5—7 cm longa, 2—3,5 cm 
lata, supra fusco-viridia, glaberrima, subtus pallidiora, secus nervos 
primarios albido-pilosa, margine ciliolata, petiolo 0,75 —1 cm longo-fus- 
cescenti instructa. Paniculae terminales vel laterales effusae. elongatae, 
15—25 cm longae, paucibracteatae. Flores flavido-rubelli. Calyx cam- 
panulatus, subtruneatus, 0,2 em longus. Corollae tubus anguste cylin- 
dricus, 0,8 cm longus, 0,2 cm dimetiens: lobi oblongo-ovati, subacuti. 
Stamina corolla inclusa. Fructus laevis. longitudinaliter striatus, acutus, 
1 cm longus, 0,3 cm dimetiens. 
Die Beschreibung dieser neuen Syringa bezieht sich auf Kulturexem- 
plare, die aus dem Arboretum des Herrn Max von Sivers in Roemers- 
hof bei Riga stammen. Sie ist ein hoher, in Roemershof winterharter 
Strauch, wahrscheinlich aus Ostasien. 
Nahe verwandt mit S. rosea (Cornu) Lingelsh., weicht jedoch durch 
die Blütenfarbe und die glatten, spitzen Früchte genügend ab. 
Die Neueinführung dieser Pflanze in die gärtnerische Kultur ist des- 
halb besonders wertvoll, da die Farbe der sehr grossen und reichlich 
auftretenden Rispen nach Angabe des Herrn von Sivers ein prachtvolles 
Hellachsfarben darstellt.
