C{ ,i plant I have seen uo specimen, but from the description it seems related to the preceding species. 

 f - ( bubnum urceolatum, Siebold & Zuccarini. See p. 87, t. 141. 



ntimetres long and from 1.5 to 4 ceutimetres broad, with from seven to ten pairs of veins curving and 



storoosing before reaching the margins and slightly impressed above and elevated beneath; petioles grooved, about 1 o.nti- 

 metre in length, densely stellate-tomentose. Corymbs terminal, from 4 to 5.5 centimetres in diameter, densely itellate-tomentoee, 

 on a peduncle about 2.5 centimetres long; rays usually seven, of nearly equal length; flowers short-pedicellate, with linear-lance- 

 olate bractlets at the base, on rays of the second and third order; ovary oblong-ovoid, nearly 3 millimetres long, sparingly stellate 

 like the broadly ovate calyx-lobes; corolla rotate-campanulate, nearly 5 millimetres high, sparingly stellate outside, the lobe* 

 orbicular, shorter than the tube; stamens exceeding the lobes; anthers oval, yellow; style slightly exceeding the calyx-lobe*. 

 Drupe oblong-ovoid, crowned by the persistent calyx; stone much compressed, 8 millimetres high and 5 millimetres broad, with 

 three ventral and two dorsal grooves. 



A shrub, about 1 metre high, with terete branches, loosely stellate-tomentose while young, soon becoming glabrous, and light 

 yellowish brown and marked by scattered small lenticels. Winter-buds naked. 



China: banks of the Yang-tse-kiang River, Kiu Fu, E.H. Wilson (No. 3726 in Herb. Arnold Arboretum). 



Viburnum hypoleucum is most closely related to Viburnum Bockii, Gnibner, but is easily distinguished from that species by the 

 pure white tomentum on the under surface of the much larger leaves.

30. \ iburnum congestum, n. sp. 



Leaves coriaceous, oval to ell lptic-ovate, obtuse or acutish, rounded or narrowed at the base, entire, dark ><•!]„« is!, gr, <-n, 

 furnished while very young with scattered stellate hairs but soon becoming glabrous on the upper .urface, r.ivered <"> the lower 

 surface with grayish white or yellowish white stellate tomentum, from 2 to 4 centimetres long, with only ^ K i,tly impressed veins; 

 petioles densely tomentose, from 0.5 to 1 centimetre in length. Corymbs terminal and lateral, small and den*.-, b 

 centimetres in diameter, on peduncles from 5 to 10 millimetres long and like the rays stellate-tomentose; rays five, short and 



angular; flowers sessile on rays of the first and second order; ovary and the broadly ovate short calyx-lobee gla r lis 



eampanulate-infundibuliform, 5 millimetres high, glabrous, the lobes orbicular-ovate, about half as long as the tube; stamens 

 about as long as the lobes; anthers oval, yellow; style exceeding the calyx-lobes. Fruit unknown. 



A shrub, about 1.30 metres high (according to A. Henry), with branchlets densely covered with grayish white stellate tomentum, 

 more or less persistent until their third year. Winter-buds naked. 



China: Yunnan, Mengtze, woods, altitude 1600 metres, A. Henry (No. 9 683 A in Herb. Kew, type); Tapin-tze, Dehway — 

 (No. 929 in Herb. Kew). 



Viburnum congestum is most closely related to Viburnum utile, Hemsley, differing chiefly from that species in its smaller infun- 

 dibuliform corolla, the dense and small inflorescence, and the absence of fulvous scales in the tomentum. It seems a rather 

 variable species: Henry's specimen No. 9683 A in the herbarium of the Arnold Arboretum differs from the type at Kew in its 

 larger leaves only thinly covered with stellate tomentum on the lower surface, while Delavay's specimen has larger acutisb leaves 

 covered beneath with a close yellowish or grayish white tomentum, and a somewhat less dense corymb.
