NOTES ON HALORRHAGACEiE 135 



the field, duly represents the natural state of things, but that its 

 relationship to nitidits and affinis is the most frequent. When its 

 petals have a tint of lilac, as mentioned by Mr. Rogers, it has been 

 noticed by me to have also other signs of a connection with Bal- 

 fouriamis — a very common Ritbus here. 



R. affinis is abundant here, and a very distinct species, R. 

 holerythros Focke I have not been able to make out as a distinct 

 species. The name seems to have been applied to luxuriant 

 specimens of affinis, and to intermediates (hybrids?) occasionally 

 occurring between affinis and some Ehamnifolian. R. affinis x 

 dumnoniensis and x carpinifolixis may, I believe, be occasionally 

 found upon our common. 



Mr. Eogers says that R. rhombifolius Weihe, which includes, so 

 Dr. Focke states, R. carpinifolius /3 roseus, cannot always be dis- 

 tinguished from R. holerythros. It seems to me that there is good 

 reason to think this is because they are both hybrids of affinis 

 with the same or different Rhamnifolians ; and that some of 

 these hybrids are as much like one as the other, holerythros and 

 rlwmbifolius — that they are a hybrid, variable as hybrids always 

 must be. 



It will thus be seen that the reputed rarity of a Rubns runs 

 very much with its thinness of distribution and its indefiniteness 

 of distinction.

NOTES ON HALORRHAGACE^l. 



By James Britten, F.L.S. 



Last autumn Dr. A. K. Schindler visited the National Her- 

 barium and went through our Ilalorrhagacece, making interesting 

 notes upon the sheets. He had not seen the Herbarium before 

 publishing his monograph of the order (Das Pflanzenreich 3 23 Heft 

 (iv. 225)), and it may be worth while to print certain of his 

 determinations, especially of Robert Brown's Australian plants, 

 which supplement the information therein given. The notes 

 follow the order of the monograph. 



Haloragis scabra Benth. The type of the species — Ooniocarpus 

 scaber Koenig in Ann. Bot. i. 547 (1805) {Ludiciffia octandra Banks 

 Herb. !) from Macao, D. Nelson, 1780— is referred by Dr. Schindler 

 to his var. a elongata. 



H. Meziana Schindler. B. Brown, Iter Austral, no. 4554. 



H. rubra Schindler. Walter's plant, on which this is based, 

 was distributed by Mueller as H. tetragyna. 



H. tetragyna Hook. f. No. 4416 of Brown's collection (from 

 Port Jackson) consists of three plants, named by Schindler respec- 

 tively H. tetragyna var. genuina, H. tetragyna var. bicallosa, and //. 

 teitcrioides. No. 4115, from "perforated granitic mountain, Bay I.
