which is rosy red. It grows rapidly in the open air even 

 in the northern part of the state. C. Siphonanthus, of India, 

 is one of the most common plants in the gardens of Florida. 

 It grows eight to ten feet high, without branching, and, 

 though not very beautiful, is always conspicuous, especially 

 when covered with its dark bluish terminal clusters of 

 berries.

 Lonicera Korolkowii. 



THIS handsome plant, which is conspicuous throughout 

 the summer from the color of the pale glaucous green 

 foliage, quite unlike that of the leaves of any other Honey- 

 suckle in the collection, was sent to the Arboretum in 18S1 

 by the late Alphonse Lavallee, of Segrez, in France, who 

 had obtained it through Colonel Korolkow, of Moscow. 

 Being unable to refer it here to any described species, it 

 was sent to the Herbarium at Kew for determination, 

 and, at our request, Dr. Stapf, finding it undescribed, has 

 prepared the following description to accompany the illus- 

 tration on page 35 of this issue, taken from a drawing made 

 by Mr. Faxon in the Arboretum. 



Lonicera Korolkowii has grown here into a stout spread- 

 ing bush six or eight feet tall ; here it flowers about the 1st 

 of June and ripens its fruit early in the autumn. _ _

Turkestan, Koralkow. 



I have indicated above the differences between L. Korol- 

 kowii and L. Xylosteum and L. Tatarica v. puberula, and need 

 not repeat them. The typical L. Tatarica, L., is, of course, 

 still more distinct in its being perfectly glabrous in all its 

 parts. On the other hand, L. Korolkowii is very probably 

 identical with the plant which was described by H. Zabel under 

 the name of Lonicera floribunda Boiss. et Buhse in Gartenflora, 

 1889, p. 525, and figured by A. Rehder in Gartenflora, 1893, 

 p. 103. Zabel's description especially fits L. Korolkowii, as 

 represented by the specimens grown in the Arboretum of 

 Harvard University. Rehder quotes Zabel's article and evi- 

 dently intends to represent the same plant by his figure, and 

 the only difference I find in comparing this with the specimens 

 from which my description of L. Korolkowii was drawn, is 

 that the corolla lobes are rather broader and the corolla alto- 



gether a trifle shorter in the former. But this may certainly 

 be considered as insignificant, and we may sately assume the 

 identity of L. Korolkowii and L. floribunda of Zabel and of 

 Rehder. But Zabel as well as Rehder, and evidently also 

 Dippel in " Handbuch der Laubholzkunde," were mistaken 

 in referring this plant, winch was introduced from Turkestan 

 through the Botanic Garden at St. Petersburg, to L. floribunda, 

 Boiss. et Buhse. Zabel, who first made this suggestion, states 

 himself that he had not seen any authentic specimen of L. 

 floribunda, Boiss. et Buhse, but had to rely on the plate, pub- 

 lished in " Boissier und Buhse Aufzahlungder in Transkau- 

 kasien und Persien gesammeltau Pflanzeu," p. 107, t. 8. Buhse 

 collected L. floribunda in two localities in the province of 

 Mazanderan, on the Caspian Sea, at Warahusol and at Radkan, 

 the latter south-east of Asterabad, in June and July respectively 

 of 1848, both times in fruit only. From these specimens the 

 original description and the figure were drawn. Ten years 

 later the same plant was collected by Dr. Bunge early in 

 March and a few miles northwest of Radkan, at Alfresh, not 

 far from the lagoon of Asterabad. His specimens were in 

 blossom, and it was from them that Boissier added the de- 

 scription of the flower in the " Flora Orientalis." One of 

 Bunge's specimens is preserved in the Kew Herbarium. It is 

 quite different from what was described and figured by Zabel 

 and Rehder respectively under the name of L. floribunda, and 

 approaches, in fact, so very much L. Tatarica that it is not easily 

 distinguished. From L. Korolkowii it differs in the leaves, 

 which are more rounded and almost truncate at the base, and 

 hairy only beneath along the midrib, in the glabrous bracts, 

 bracteoles and calyx lobes, which are quite those of typical 

 L. Tatarica, and in the shorter corolla with broader lobes and 

 a more pronounced gibbosity at the base of the tube. Rehder 

 quotes also L. Tatarica, L. B. micrantha, Trautv., L. micrantha, 

 Regel, as a synonym of his L. floribunda. If that be the case, 

 the species described here would not be new. I have not 

 seen authentic specimens of L. micrantha, Reg., but the de- 

 scriptions of this plant by Trautvetter, as well as by Regel, and 

 the description and figure of it in Dippel's " Handbuch der 

 Laubholzkunde," pp. 232, 233, represent a plant with flowers 

 only half the size of those ot L. Tatarica (vig. 33^2 lin., while 

 they are 6 7 lin. in L. Korolkowii).

Acacia Baileyana. — This is a distinct and beautiful spe- 

 cies which has recently been introduced into English gar- 

 dens by means of seeds sent by Baron Sir F. von Mueller, 

 the eminent Australian botanist. There are several good 

 bushes of it in the Kew collection, and it is also grown in 

 the Cambridge Botanic Garden, where it has lately flow- 

 ered. It is of close, bushy habit, with stiff twiggy branches, 

 thickly clothed with short, bipinnate, short-stalked leaves, 

 as glaucous as those of A. dealbata, and with remarkably 

 large glandules on the midrib. The flowers are in small- 

 stalked, spherical heads, deep yellow, fragrant, and pro- 

 duced in large, elegant panicles on the ends of the branches. 

 In Australia this species is said to form a small tree, fifteen 

 feet high, of particularly graceful aspect, the gray bark of the 

 trunk and branches and the silvery hue of the leaves being 

 an excellent foil to the numerous panicles of golden yellow 

 flowers. I have had a spray of flowers in water a week, 

 and they are still fresh. 



Graderia subintegra. — This is a new 

 which has lately been found in south 

 are now offered by Mr. W. Nelson, a nurseryman in 

 Johannesburg, who describes it as "a very handsome and 

 uncommon-looking plant — a trailer, herbaceous, three inches 

 high, producing Gloxinia-like pink flowers, with lighter 

 shade in the interior of the flower." A botanical description 

 by Dr. Masters and an excellent figure of the plant are pub- 

 lished in the Gardeners' Chronicle for December 30th. From 

 these it is clear that this Graderia is a beautiful little plant, 

 with an erect spike six inches long, closely packed with 

 Pentstemon-like flowers, and very attractive in appearance 

 at any rate. There is, however, the suspicion that this plant 

 is one of many very beautiful Scrophulariads found in south 

 Africa which have never, so far, been successfully cul- 

 tivated because of their semi-parasitical habit. Such plants
